functional-benchmarker

README

functional-benchmarker

This is an internal utility based on the project's functional test framework which allows benchmarking OpenShift Logging's efficiency in processing messages. The intention is to use this utility to assess changes to the processing pipelines.

Requirements

• gnuplot for reporting

Building

make bin/functional-benchmarker

Results

The benchmark utility will generate results in a directory prefixed with "benchmark" and write similiar results to stdout.

$ ./bin/functional-benchmarker

Platform notes

Running on crc requires enabling monitoring and adding more memory:

 crc config set enable-cluster-monitoring true
 crc start -m16384
