Resource Allocations

Allot CPU and RAM resources to services, per service, per server.

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 Packages section.

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.
