The goal of this POC is to verify the SDK implemented in https://perconadev.atlassian.net/browse/PBM-780 to be used in PMM for monitoring.

Goal: present PBM metrics and backup information in PMM using the existing connection to MongoDB. This will let us cover a lot of “Backup Alerting“ requests from https://perconadev.atlassian.net/browse/PMM-12728 by using already monitored MongoDB and cover different PBM deployment scenarios (manual pdb, Everest) w/o the need for PMM to be the manager of the PBM.

Original idea: extend MongoDB exporter with a new collector and use the SDK to get data from MongoDB and convert them to logical information.

Metrics to expose:

• Is the backup configured for the cluster this instance belongs to?

• Is the PITR on for the backup?

• Existed backups and their size

• Currently running backups and their statuses
