Hi all, I want to start a discussion to cherry-pick #21816[0] to release branches. This PR added the metrics for the time-based backlog, which is introduced in 2.8.0 [1]. However, there has always been a lack of relevant indicators to assist users in daily monitoring work. It becomes a blocker for users to use the time-based backlog on production, and it is hard to add alerts and dashboards.
Since #21816 is not a BUG fix, it hasn't been cherry-picked to release branches. But now, I believe having it in the release branches is worth it. The target branches: - branch-3.2 - branch-3.0 - branch-2.11 - branch-2.10 [0] https://github.com/apache/pulsar/pull/21816 [1] https://github.com/apache/pulsar/pull/10093 I will keep the discussion open for at least 48 hours. If there is no objections, I will perform the cherry-picking. Regards, Penghui
