# 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]
```
