Generate sample Prometheus data Rake task

This command runs Prometheus queries for each of the metrics of a specific environment for a series of time intervals to now:

  • 30 minutes
  • 3 hours
  • 8 hours
  • 24 hours
  • 72 hours
  • 7 days

The results of each of query are stored under a sample_metrics directory as a YAML file named by the metric’s identifier. When the environmental variable USE_SAMPLE_METRICS is set, the Prometheus API query is re-routed to Projects::Environments::SampleMetricsController which loads the appropriate data set if it is present within the sample_metrics directory.

This command requires an ID from an environment with an available Prometheus installation.


The following example demonstrates how to run the Rake task:

bundle exec rake gitlab:generate_sample_prometheus_data[21]
