Sample Prometheus data Rake task (FREE SELF)
The Rake task 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 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's present in the sample_metrics directory.
The Rake task requires an ID from an environment with an available Prometheus installation.
Example
The following example demonstrates how to run the Rake task:
bundle exec rake gitlab:generate_sample_prometheus_data[21]
