The Barman Cloud Plugin exposes the following metrics through the native Prometheus exporter of the instance manager:
-
barman_cloud_cloudnative_pg_io_last_failed_backup_timestamp: the UNIX timestamp of the most recent failed backup. -
barman_cloud_cloudnative_pg_io_last_available_backup_timestamp: the UNIX timestamp of the most recent successfully available backup. -
barman_cloud_cloudnative_pg_io_first_recoverability_point: the UNIX timestamp representing the earliest point in time from which the cluster can be recovered.
These metrics supersede the previously available in-core metrics that used the
cnpg_collector prefix. The new metrics are exposed under the
barman_cloud_cloudnative_pg_io prefix instead.
