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_replica_status: Status of replication for each bucket.
• purefb_buckets_replica_backlog_size: Size of the backlog for each replicated bucket.
• purefb_buckets_replica_lag: Replication lag per bucket.
• purefb_buckets_replica_operations{type="put|delete|other"}: Number of operations per bucket, categorized by type.

Labels for each metric:

• bucket_name: Name of the replicated bucket.
• remote_host: Hostname of the remote destination.

General replication metrics:

• purefb_buckets_replica_backlog_size_total: Total backlog size across all replicated buckets.
• purefb_buckets_replica_operations_total{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
