Chapter 14, Integrating Long-Term Storage with Prometheus
- The main advantages of basing the remote write feature on the WAL are: it makes streaming of metrics possible, has a much smaller memory footprint, and it’s more resilient to crashes.
- You can request Prometheus to produce a snapshot of the TSDB by using the /api/v1/admin/tsdb/snapshot API endpoint (only available when the --web.enable-admin-api flag is enabled), and then back up the snapshot.
- You can delete time series from the TSDB by using the /api/v1/admin/tsdb/delete_series API endpoint and then using the /api/v1/admin/tsdb/clean_tombstones to make Prometheus clean up the deleted series (these endpoints will only be available when the --web.enable-admin-api flag is enabled).
