Generate Sample Prometheus Data

This command will run Prometheus queries for each of the metrics of a specific environment for a default time interval of 7 days ago to now. 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.

Example:

bundle exec rake gitlab:generate_sample_prometheus_data[21]
