Benchmark Runner Tool

Benchmark-Runner

This tool provides a lightweight and flexible framework for running benchmark workloads on Kubernetes/OpenShift Pod or VM.

This tool support the following workloads:

• hammerdb: running hammerdb workload on the following databases: MSSQL, Mariadb, Postgresql on Pod and VM with Configuration
• stressng: running stressng workload on Pod or VM with Configuration
• uperf: running uperf workload on Pod or VM with Configuration
• vdbench: running vdbench workload in a pod with Configuration

Benchmark-runner grafana dashboard example:

Reference:

• The benchmark-runner package is located in PyPi
• The benchmark-runner container image is located in Quay.io

[TBD]

Grafana dashboards

There are 3 grafana dashboards templates:

1. benchmark-runner-ci-status-report.json
2. benchmark-runner-report.json

** After importing json in grafana, you need to configure elasticsearch data source. (for more details: see HOW_TO.md)

Inspect Prometheus Metrics

The CI jobs store snapshots of the Prometheus database for each run as part of the artifacts. Within the artifact directory is a Prometheus snapshot directory named:

promdb-YYYY_MM_DDTHH_mm_ss+0000_YYYY_MM_DDTHH_mm_ss+0000.tar

The timestamps are for the start and end of the metrics capture; they are stored in UTC time (+0000). It is possible to run containerized Prometheus on it to inspect the metrics. Note that Prometheus requires write access to its database, so it will actually write to the snapshot. So for example if you have downloaded artifacts for a run named hammerdb-vm-mariadb-2022-01-04-08-21-23 and the Prometheus snapshot within is named promdb_2022_01_04T08_21_52+0000_2022_01_04T08_45_47+0000, you could run as follows:

$ local_prometheus_snapshot=/hammerdb-vm-mariadb-2022-01-04-08-21-23/promdb_2022_01_04T08_21_52+0000_2022_01_04T08_45_47+0000
$ chmod -R g-s,a+rw "$local_prometheus_snapshot"
$ sudo podman run --rm -p 9090:9090 -uroot -v "$local_prometheus_snapshot:/prometheus" --privileged prom/prometheus --config.file=/etc/prometheus/prometheus.yml --storage.tsdb.path=/prometheus --storage.tsdb.retention.time=100000d --storage.tsdb.retention.size=1000PB

and point your browser at port 9090 on your local system, you can run queries against it, e. g.

sum(irate(node_cpu_seconds_total[2m])) by (mode,instance) > 0

It is important to use the --storage.tsdb.retention.time option to Prometheus, as otherwise Prometheus may discard the data in the snapshot. And note that you must set the time bounds on the Prometheus query to fit the start and end times as recorded in the name of the promdb snapshot.
