Buckets replication metrics

[maxkushnir]

We are requesting the addition of new metrics to track the replication of buckets. The proposed metrics would offer detailed insights on a per-replicated bucket basis and also provide general replication metrics at the device level.

Proposed Metrics:

Per-replicated bucket:

• _purefb_buckets_replicastatus: Status of replication for each bucket.
• _purefb_buckets_replica_backlogsize: Size of the backlog for each replicated bucket.
• _purefb_buckets_replicalag: Replication lag per bucket.
• _purefb_buckets_replicaoperations{type="put|delete|other"}: Number of operations per bucket, categorized by type.

Labels for each metric:

• _bucketname: Name of the replicated bucket.
• _remotehost: Hostname of the remote destination.

General replication metrics:

• _purefb_buckets_replica_backlog_sizetotal: Total backlog size across all replicated buckets.
• _purefb_buckets_replica_operationstotal{type="put|delete|other"}: Total replication operations, categorized by type.

These metrics will greatly improve visibility into the replication status and performance of buckets.

Thank you for considering this request!

Hi! Yes, I agree these metrics would be a great addition! Thank you for the feedback, i will keep this issue open as we develop this
