HMC Insights

HMCi is a small utility to fetch metrics from one or more HMC's and push those to an InfluxDB time-series database.

Usage Instructions

  • Ensure you have correct date/time and NTP running to keep it accurate!
  • Install HMCi .deb or .rpm file from downloads or compile from source
  • Copy the doc/hmci.groovy.tpl configuration template into /etc/hmci.groovy and edit the configuration to suit your environment
  • Configure Grafana to communicate with your InfluxDB and import dashboards from doc/ into Grafana (The dashboards are slightly modified versions of the dashboard provided by the nmon2influxdb tool)
  • Run the bin/hmci program in a shell, as a @reboot cron task or setup a proper service :)

Power Binaries

You can download Grafana and InfluxDB ppc64le packages for most Linux distributions and AIX from the Power DevOps site.

Notes

Examples on how to change the default InfluxDB retention policy:

 ALTER RETENTION POLICY "autogen" ON "hmci" DURATION 156w
 ALTER RETENTION POLICY "autogen" ON "hmci" DURATION 90d

InfluxDB and Grafana Packages

You can download Grafana ppc64le and InfluxDB ppc64le packages for most Linux distributions and AIX on the Power DevOps site.

Binaries for amd64/x86 are available from the Grafana website and InfluxDB website and also directly from your Linux distribution repository in some cases.

Development Information

You need JDK version 8 or later.

Build & Test

Use the gradle build tool, which will download all required dependencies.

./gradlew clean build

InfluxDB for local testing

Start the InfluxDB container

docker run --name=influxdb --rm -d -p 8086:8086 influxdb

To use the Influx client from the same container

docker exec -it influxdb influx

Grafana for local testing

Start the Grafana container, linking it to the InfluxDB container

docker run --name grafana --link influxdb:influxdb --rm -d -p 3000:3000 grafana/grafana:7.1.3

Configure a new InfluxDB datasource on http://influxdb:8086 named hmci to connect to the InfluxDB container. The database must be created beforehand, this can be done by running the hmci tool first. Grafana dashboards can be imported from the doc/ folder.
