Observability

When running cluster mode the GMT execute automated processes through cron jobs but also through control workloads.

Nonetheless there is the basic operation of the webserver and database to have a central datastore and provide a dashboard.

GMT provides two approaches to get insights into the cluster operations.

Status Page

Under the /status.html page of your GMT installation you can find a status page that contains:

  • Currently configured machines in the cluster
  • Current temperature, installed GMT version and measurement configuration of the machines in the cluster
  • Waiting times for scheduling a jobs on the machines in the cluster
  • Current jobs in the queue for the cluster

Energy consumption & CO2 emissions

Measuring and deriving optimizations costs a lot of energy and it is crucial to understand how much you savings in energy and carbon emissions you gain.

To provide insights and execute net-gain analysis we provide an extension to the Green Metrics Tool called CarbonDB.

In essence it is an aggregate dashboard that gathers all energy and carbon data from our tools that submit their data to the GMT API.

In the CarbonDB Dashboard you can find:

  • CI/CD energy and carbon data from Eco-CI
  • Benchmarking energy and carbon data from Green Metrics Tool runs
  • Developer machine energy and carbon data from PowerHOG
  • Custom energy and carbon data from CarbonDB Agents configured
    • A typical setup for instance is to install a CarbonDB Agent on the database server as well as the Frontend / Dashboard server
