OpenHIM platform is an easy way to set up, manage and operate a Health Information Exchange (HIE). Specifically, it is the following:

• A toolbox of open-source tools, grouped into packages, that are used within an HIE.

• The glue that ties these tools together. These are often in the form of OpenHIM mediators which are just microservices that talk to OpenHIM.

• A CLI tool to deploy and manage these packages.

The Problem

We at Jembi want to stop rebuilding solutions from near scratch each time we need an HIE implementation. It would be beneficial to us and others doing the same work to focus more on the unique needs of a country rather than the intricacies of a production deployment of an HIE.

Operating production-grade HIE systems is hard, because of these issues:

• Need to support up to national scale

• An always-present need for high level of security

• Difficulty of deploying complex systems that have many components

The Solution

OpenHIM Platform provides an opinionated way to deploy, secure and scale highly-available services for an HIE environment. It provides a set of services to solve common HIE challenges:

• Patient matching

• FHIR support

• Reporting services

OpenHIM platform comes bundled with a set of generic packages that can be deployed and configured to support a number of different use cases. To help users of OpenHIM Platform get started with something they can make use of immediately, a number of default OpenHIM Platform recipes are provided. These help you get started with everything you need setup and configured for a particular use case.

These recipes combine and configure multiple packages together so that a functional HIE is stood up that is pre-configured to support a particular use case.

We currently support the following default recipes:

Package can be stood up individually using the instant package init -n <package_name> command, or they can be included in your own recipes. This can be accomplished by that includes the necessary packages and any custom configuration packages.

This recipe sets up an HIE that deploys JeMPI behind the OpenHIM with a mapping mediator configured to allow for FHIR-based communication with JeMPI. It also deploys Keycloak for user management and authentication.

To launch this package in dev mode copy and paste this into your terminal in a new folder (ensure you have the instant CLI installed):

wget https://github.com/jembi/platform/releases/latest/download/mpi.env && \
wget https://github.com/jembi/platform/releases/latest/download/config.yaml && \
instant package init -p mpi --dev

The monitoring package sets up services to monitor the entire deployed stack. This includes the state of the servers involved in the docker swarm, the docker containers themselves and particular applications such as Kafka. It also captures the logs from the various services.

This monitoring package uses:

• Grafana: for dashboards

• Prometheus: for recording metrics

• Cadvisor: for reading docker container metrics

• Loki: for storing logs

• Node Exporter: for monitoring host machine metrics like CPU, memory etc

To use the monitoring services, include the monitoring package id to your list of package ids when standing up the platform.

Adding application specific metrics

The monitoring service utilises service discovery to discover new metric endpoints to scrape.

To use custom metrics for an application, first configure that application to provide a . Then, let the monitoring service know about it by configuring specific docker service labels that tell the monitoring service to add a new endpoint to scrape. E.g. see lines 8-9:

prometheus-job-service lets Prometheus know to enable monitoring for this container and prometheus-address gives the endpoint that Prometheus can access the metrics on. By default this is assumed to be at the path /metrics by Prometheus.

By using the prometheus-job-service label prometheus will only create a single target for your application even if it is replicated via service config in docker swarm. If you would like to monitor each replica separately (i.e. if metrics are only captured for that replica and not shared to some central location in the application cluster) you can instead used the prometheus-job-task label and Prometheus will create a target for each replica.

A full list od supported labels are listed below:

• prometheus-job-service - indicates this service should be monitored

• prometheus-job-task - indicates each task in the replicated service should be monitored separately

• prometheus-address

All services must also be on the prometheus_public network to be able to be seen by Prometheus for metrics scraping.

Adding additional dashboards

To add additional dashboards simply use docker configs to add new Grafana dashboard json files into this directory in the Grafana container: /etc/grafana/provisioning/dashboards/

That directory will be scanned periodically and new dashboards will automatically be added to Grafana.

Grafana dashboard json file may be exported directly from the Grafana when saving dashboards or you may lookup the many existing dashboard in the .

This recipe sets up an HIE that does the following:

• Accept FHIR bundles submitted securely through an IOL (OpenHIM)

• Stores Clinical FHIR data to a FHIR store (HAPI FHIR)

• Stores Patient Demographic data to an MPI (JeMPI)

• Pushes FHIR resources to Kafka for other external systems to use

To launch this package in dev mode copy and paste this into your terminal in a new folder (ensure you have the ):

Accessing the services

OpenHIM

• Console: http://127.0.0.1:9000

• Username: root@openhim.org

• Password: instant101

Testing the Interoperability Component

As part of the Interoperability Layer setup we also do some initial config import for connecting the services together.

• OpenHIM: Import a channel configuration that routes requests to the Data Store - HAPI FHIR service

This config importer will import channels and configuration according to the file openhim-import.json in the folder <path to project packages>/interoperability-layer-openhim/importer/volume.

Prerequisites

Before getting started with OpenHIM Platform you will need to have Instant OpenHIE tool installed and functional. .

Quick Start

Ensure Docker Swarm in initialised:

Download the latest OpenHIM Platform config file which configures Instant OpenHIE v2 to use OpenHIM Platform packages:

Download the latest environment variable file, which sets configuration options for OpenHIM Platform packages:

Launch some OpenHIM Platform packages, e.g.

This launches the OpenHIM and Kafka packages in dev mode (which exposes service ports for development purposes) using the config supplied in the env var file.

To destroy the setup packages and delete their data run:

Next, you might want to browse the available in OpenHIM Platform. Each recipe bundles a set of packages and configuration to setup an HIE for a particular purpose.

For example, this command allows the most to be deployed with one command:

Alternatively you can also browse the individual set of that OpenHIM Platform offers. Each package's documentation lists the environment variables used to configure them.

For more information on how to start stop and destroy packages using the command line, see the .

Please for support or to chat about new features or ideas.

Kafka-mapper-consumer

A Kafka processor that will consume messages from Kafka topics. This messages will be mapped according to the mapping defined in the file called fhir-mapping.json.

This flattened data will be then sent to Clickhouse DB to be stored.

Logstash provides a data transformation pipeline for analytics data. In the platform it is responsible for transforming FHIR messages into a flattened object that can be inserted into Elasticsearch.

Input

Logstash allows for different types of input to read the data: Kafka, HTTP ports, files, etc.

This recipe sets up an HIE that does the following:

Adding pipelines and configs

To add Logstash config files, you can add files into the <path to project packages>/data-mapper-logstash/pipeline.

Ofelia - Job Scheduler

The platform uses image: mcuadros/ofelia:v0.3.6 which has the following limitations:

The Ofelia service does not make use of any environment variables. However, when specifying jobs in the config.ini file(s) we can pass any environment variable in.

Example:

[job-run "mongo-backup"]
schedule= @daily
image= mongo:4.2
network= mongo_backup
volume= /backups:/tmp/backups
command= sh -c 'mongodump --uri=${OPENHIM_MONGO_URL} --gzip --archive=/tmp/backups/mongodump_$(date +%s).gz'
delete= true

This component consists of two services:

• Interoperability Layer - OpenHIM for routing the events

• Mongo DB for storing the transactions

It provides an interface for:

1. Checking the transactions logs

2. Configuring the channels to route the events

3. User authentication logs

OpenHIM is based on two 3 main services, openhim-core as a backend, openhim-console as a frontend and mongo as a database.

It is a mandatory component in the stack and the entry point for all incoming requests from the external systems.

Launching

Launching this package follows different steps:

• [Cluster mode] Creating certificates and configuring the nodes

• Running Elasticsearch

• Setting Elasticsearch passwords

• Importing Elasticsearch index

Importing

To initialize the index mapping in Elasticsearch, a helper container is launched to import a config file to Elasticsearch. The config importer looks for a field named fhir-enrich-report.json in <path to project packages>/analytics-datastore-elastic-search/importer.

The file fhir-enrich-report.json will contain the mapping of the index fhir-enrich-reports.

Elasticsearch will create a dynamic mapping for the incoming data if we don't specify one, this dynamic mapping may cause issues when we start sending the data as it doesn't necessarily conform 100% to the data types that we're expecting when querying the data out of Elasticsearch again.

Therefore, the mapping should be initialized in Elasticsearch using the config importer.

The file fhir-enrich-report.json is just an example, the name and the mapping can be overridden.

Running in Dev Mode

When running in DEV mode, Elasticsearch is reachable at:

http://127.0.0.1:9201/

Elasticsearch Backups

For detailed steps about creating backups see: .

Elasticsearch offers the functionality to save a backup in different ways, for further understanding, you can use this link: .

Elasticsearch Restore

To see how to restore snapshots in Elasticsearch: .

This package consists of four services:

• Postgres Main DB

• Postgres Audit DB

• SanteMPI Web UI -

• SanteMPI API -

Pre-Deploy Configuration

If running in clustered mode, take note that each machine has to have the following vm.max_map_count setting:

sysctl -w vm.max_map_count=262144

Launching

Launching this package executes the following two steps:

• Running Clickhouse service

• Running config importer to run the initial SQL script

Initializing ClickHouse

The config importer will be launched to run a NodeJS script after ClickHouse has started.

It will run SQL queries to initialize the tables and the schema, and can also include initial seed data if required.

The config importer looks for two files clickhouseTables.js and clickhouseConfig.js found in <path to project packages>/analytics-datastore-clickhouse/importer/config.

For specific implementation, this folder can be overridden.

Note

The environment variable SANTEMPI_REPMGR_PARTNER_NODES will differ from cluster and single mode.

Default value for SANTEMPI_MAIN_CONNECTION_STRING:

Default value for SANTEMPI_AUDIT_CONNECTION_STRING:

Accessing the Service

Jsreport - http://127.0.0.1:5488/

Scripts/Templates Development

When seeking to make changes to the Jsreport scripts/templates without having to repeatedly start and stop the service, one can set the JS_REPORT_DEV_MOUNT environment variable in your .env file to true to attach the service's content files to those on your local machine.

Export & Import

After editing the templates in Jsreport, you will need to save these changes, it is advised to export a file containing all the changes named export.jsrexport and put it into the folder <path to project packages>/dashboard-visualiser-jsreport/importer.

The config importer of Jsreport will import the export.jsrexport and then all the templates, assets, and scripts will be loaded in Jsreport.

Accessing the Service

Kibana - http://127.0.0.1:5601/

Importing Saved Objects

The config importer will import the file kibana-export.ndjson that exists in the folder <path to project packages>/dashboard-visualiser-kibana/importer.

The saved objects that will be imported are the index patterns and dashboards. If you made any changes to these objects please don't forget to export them and save the file kibana-export.ndjson under the folder specified above.

Version upgrade process (with rollback capability)

By default if you simply update the image that the superset service uses to a later version, when the container is scheduled it will automatically run a database migration and the version of superset will be upgraded. The problem, however, is that if there is an issue with this newer version you cannot rollback the upgrade since the database migration that ran will cause the older version to throw an error and the container will no longer start. As such it is recommended to first create a postgres dump of the superset postgres database before attempting to upgrade superset's version.

1. Exec into the postgres container as the root user (otherwise you will get write permission issues)

1. Run the pg_dump command on the superset database. The database name is stored in SUPERSET_POSTGRESQL_DATABASE and defaults to superset

1. Copy that dumpped sql script outside the container

1. Update the superset version (either through a platform deploy or with a docker command on the server directly -- docker service update superset_dashboard-visualiser-superset --image apache/superset:tag)

Rolling back upgrade

In the event that something goes wrong you'll need to rollback the database changes too, i.e.: run the superset_backup.sql script we created before upgrading the superset version

1. Copy the superset_backup.sql script into the container

1. Exec into the postgres container

1. Run the sql script (where -d superset is the database name stored in SUPERSET_POSTGRESQL_DATABASE)

Accessing the Service

Superset - http://127.0.0.1:8089/

Using the superset_config.py file

The Superset package is configured to contain a superset_config.py file, which Superset looks for, and subsequently activates the contained feature flags. For more information on the allowed feature flags, visit .

Importing & Exporting Assets

The config importer written in JS will import the file superset-export.zip that exists in the folder <path to project packages>/dashboard-visualiser-superset/importer/config. The assets that will be imported to Superset are the following:

• The link to the Clickhouse database

• The dataset saved from Clickhouse DB

• The dashboards

If you made any changes to these objects please don't forget to export and save the file as superset-export.zip under the folder specified above. NB! It is not possible to export all these objects from the Superset UI, you can check the Postman collection: CARES DISI CDR -> Superset export assets and you will find two requests. To do the export, three steps are required:

1. Run the Get Token Superset request to get the token (please make sure that you are using the correct request URL). An example of a response from Superset that will be displayed: { "access_token": "eyJ0eXAiOiJKV1...." }

2. Copy the access token and put it into the second request Export superset assets in the Authorization section.

Your changes should then be saved.

The HAPI FHIR service will be used for two mandatory functionalities:

• A validator of FHIR messages

• A storage of FHIR message

A validator

Incoming messages from an EMR or Postman bundles are not always well structured and it may be missing required elements or be malformed.

HAPI FHIR will use a FHIR IG to validate these messages.

It will reject any invalid resources and it will return errors according to the IG.

HAPI FHIR is the first check to make sure the data injected in the rest of the system conforms to the requirements.

A storage

Backed by a PostgreSQL database, all the validated incoming messages will be stored.

This will allow HAPI FHIR to check for correct links and references between the resources, as well as another storage for backups in case the data is lost.

Instant OpenHIE FHIR Data Store Component

This component consists of two services:

• Postgres

• HAPI FHIR Server -

Accessing the services

HAPI FHIR

This service is accessible for testing via:

In a publicly accessible deployment this port should not be exposed. The OpenHIM should be used to access HAPI-FHIR.

Testing the HAPI FHIR Component

For testing this component we will be making use of curl for sending our request, but any client could be used to achieve the same result.

Execute the command below

Kafka Topics Configuration

Using a config importer, Kafka's topics are imported to Kafka. The topics are specified using the KAFKA_TOPICS environment variable, and must be of syntax:

topic or topic:partition:replicationFactor

Using topics 2xx, 3xx, and metrics (partition=3, replicationFactor=1) as an example, we would declare:

KAFKA_TOPICS=2xx,3xx,metrics:3:1

where topics are separated by commas.

Accessing Kafdrop

Kafdrop -

Components

The message-bus-kafka package consists of a few components, those being Kafka, Kafdrop, and Kminion.

Kafka

The core stream-processing element of the message-bus-kafka package.

Kafdrop

Kafdrop is a web user-interface for viewing Kafka topics and browsing consumer-groups.

Kminion

A prometheus exporter for Kafka.

A helper for Kafka message bus service, It sends data to the HAPI FHIR datastore and then to the Kafka message bus based on the response from HAPI FHIR.

More particularly:

1. It receives messages from OpenHIM

2. It sends the data to the HAPI FHIR server and waits for the response

3. It gets the response. According to the response status, it will send the message to the topic that corresponds to that status (2xx, 4xx, 5xx, ... )

4. It will send back the response from HAPI FHIR to OpenHIM as well

The kafka unbundler will consume resources of topix 2xx from Kafka, split them according to their resource type and send them again to Kafka to new topics.

Each resource type has its own topic.

Link for github repo: https://github.com/jembi/kafka-unbundler-consumer.

Nginx Reverse Proxy

This package can be used to secure all of the data transfered to and from services using SSL encryption and also to generate SSL certificates as well.

Instead of configuring each package separately, we're using this package that will hold all of the Nginx configuration.

It will generate Staging or Production certificates from Let's Encrypt to ensure a secure connection (in case we require SSL to be enabled).

It is responsible for routing network traffic to the correct service.

Structure of Reverse Proxy Nginx package

The current package contains the following:

• config: A folder that contains the general Nginx config for secure and insecure mode.

• package-conf-insecure: A folder that contains all the insecure configs related to the services that need outside access.

A job using Ofelia exists to renew the certificates automatically based on the certificate renewal period.

OpenHIM Platform builds on Instant OpenHIE v2 as the deployment tool which provides the concepts of packages, profiles and the CLI utility that powers the ability to launch OpenHIM Platform packages and recipes. Please read the the for some foundational concepts about how packages are run.

On this page we will discuss the architecture of OpenHIM Platform which is a set of packages and recipes that use those packages that create a fully functional HIE from scratch.

Modularity and flexibility

OpenHIM Platform packages are able to stood up individually so that as much or as little of the package set that is necessary from an implementer can be utilised. However, OpenHIM Platform is designed with some key features that will only be available if a number of packages are setup together. Recipes group those sets of packages together so that it is easier to deploy all at once.

Component Architecture

The architecture is split into 3 distinct parts:

• Client: This section represents client systems that might want to interact with the HIE, they have a particular set of interactions that the core OpenHIM Platform packages enable support for.

• Platform core: These are a set of packages with instantiate applications and mediators that enable the core client workflows to be executed. This includes accepting FHIR bundles, splitting patient demographic data into an MPI and clinical data into a FHIR data store as well as managing the linkage from patient demographics to clinical data in a way that isn't affected by potencial linking and unlinking of patient records via the MPI. More on this later.

• Platform pluggable services: by design, once the core packages have processed FHIR request, they are pushed into Kafka for secondary use by other systems. Typically this includes data analytics pipelines and a default implementation is included in OpenHIM Platform, however, the data can be read an used for any purpose i.e. syncing to another HIE or sent to a national data warehouse.

Platform core wokflow

This is how the core packages interact to split the data into two separate stores, a clinical data store and a patient demographics store.

The reason for doing this are as follows:

• With the clinical and patient demographic data split it is easier to link and unlink patient identities as no data in the clinical store needs to change. They continue to reference the source patient ID and whatever happen to that patient, whether they are grouped together with other identities in the MPI or not, that ID remains constant.

• The split of data is a useful security feature as the clinical data and the Personal Identifiable Information (PII) or stored separately. An attacker would need to compromise both to relate clinical information to a particular person.

• It prevent duplicate information being stored in multiple places, a clear source of truth for each type of information is identified. This prevent data from getting out of sync when it is stored in multiple places.

Cloud Dev environments

To set up a developer's development environment in AWS, run this terraform project. The scripts will allow the joining of an existing VPC, the creation of a public subnet and a variable number of EC2 instances that the user will have SSH access to. Alarms have been created in the scripts which will auto-shutdown the instances after a configurable period, based on CPU metrics. A Lambda scheduled event can also be configured which can run at a regular interval to shut down any instances that may still be running.

Pre-requisites

Creating a VPC

This should only be done once per AWS account as there is a limit of 5 per region. Please check if this has already been run and use the existing VPC_ID and SUBNET_ID for the following section if it does and skips to the next section.

Navigate to the infrastructure/terraform/vpc directory

Initialize Terraform project:

Execute the following:

Copy the output for the next step, e.g for ICAP this has already been run and this is the result:

Creating EC2 instances

Navigate to the infrastructure/terraform directory

Initialize Terraform project:

The following properties have to be set:

The configuration can be done using an terraform variable file. Create a file called my.tfvars. Below is an example that illustrates the structure of the environment variables file. This example is of a configuration that you can use for the ICAP CDR. Please replace {user} with your own user.

The AWS account to be used is defined in the ~/.aws/credentials file. If you don't have file this make sure you have configured the AWS CLI.

The sample file above has access to 3 accounts and the options for <account_name> could be "default", "jembi-sandbox", "jembi-icap"

Optionally, add ACCOUNT = "<account_name>" to my.tfvars if you want to use something other than default.

The flag for specifying an environment variables file is -var-file, create the AWS stack by running:

Once the script has run successfully, the ip addresses and domains for the servers will be displayed:

SSH access should be now available - use the default 'ubuntu' user - ssh ubuntu@<ip_address>

Destroying the AWS stack - run:

Deploying from your local environment to a remote server or cluster is easy. All you have to do is ensure the remote servers are setup as a Docker Swarm cluster. Then, from your local environment you may target a remote environment by using the `DOCKER_HOST` env var. e.g.

DOCKER_HOST=ssh://ubuntu@<ip> instant package init ...

Setting up new servers

In addition, as part of the OpenHIM Platform Github repository we also provide scripts to easily setup new servers. The Terraform script are able to instantiate server in AWS and the Ansible script are able to configure those server to be ready to accept OpenHIM Platform packages.

Ansible

See .

It is used for:

• Adding users to the remote servers

• Provision of the remote servers in single and cluster mode: user and firewall configurations, docker installation, docker authentication and docker swarm provision.

All the passwords are saved securely using Keepass.

In the inventories, there is different environment configuration (development, production and staging) that contains: users and their ssh keys list, docker credentials and definition of the hosts.

Terraform

Is used to create and set AWS servers. See .

What it Means

CPU

CPU allocations are specified as a portion of the total number of cores on the host system, i.e., a CPU limit of 2 in a 6-core system is an effective limit of 33.33% of the CPU, and a CPU limit of 6 in a 6-core system is an effective limit of 100% of the CPU.

RAM

Memory allocations are specified as a number followed by their multiplier, i.e., 500M, 1G, 10G, etc.

Defaults

As a default, each package contained in Platform is allocated a maximum of 3 GB of RAM, and 100% CPU usage.

Allocating Resources per Package

The resource allocation can be set on a per-package basis, as specified by the relevant environment variables found in the relevant .

Notes

• Be wary of allocating CPU limits to ELK Stack services. These seem to fail with CPU limits and their already implemented health checks.

• Take note to not allocate less memory to ELK Stack services than their JVM heap sizes.

• Exit code 137 indicates an out-of-memory failure. When running into this, it means that the service has been allocated too little memory.

Platform Deploy

Prerequisites

Two major procedures should exist in order to recover lost data:

• Creating backups continuously

• Restoring the backups

This includes the different databases: MongoDB, PostgreSQL DB and Elasticsearch.

Elasticsearch Backups

For detailed steps about creating backups see: Snapshot filesystem repository docs.

Elasticsearch offers the functionality to save a backup in different ways, for further understanding, you can use this link: Register a snapshot repository docs.

Elasticsearch Restore

To see how to restore snapshots in Elasticsearch: .

Adding Packages

• The Go Cli runs all services from the jembi/platform docker image. When adding new packages or updating existing packages to Platform you will need to build/update your local jembi/platform image. How to build the image.

• As you add new packages to the platform remember to list them in the config.yml file - otherwise the added package will not be detected by the .

Overview

Certain packages in the Platform require configuration to enable their intended functionality in a stack. For instance, the OpenHIM package requires the setting of users, channels, roles, and so on. Other packages, such as JS Report or Kibana, require importing of pre-configured dashboards stored in compressed files.

Most services in the Platform can be configured by sending a request containing the required configuration files to the relevant service API. To achieve this, the Platform leverages a helper container to make that API call.

The Helper Container

The Process

As part of the package-launching process, the to-be-configured service is deployed, then awaits configuring. Before the configuration can take place, the relevant service is waited upon for joining to the Docker internal network. Once the service has joined the network, the helper container is launched and makes the API request to configure the service.
