[PR] [docs] Document the OpenTelemetry metrics of the message position find by timestamp [pulsar-site]
KannarFr opened a new pull request, #1236:
URL: https://github.com/apache/pulsar-site/pull/1236
Documents the `pulsar.broker.message.find.*` OpenTelemetry metrics added in apache/pulsar#26751, as announced in that PR.
A new "Message Find Metrics" section at the end of the broker metrics describes:
- `pulsar.broker.message.find.duration`: the time taken to find the position of a message by timestamp, by reason (`seek`, `expiry`) and result (`found`, `not_found`, `failure`).
- `pulsar.broker.message.find.entry.read.count` and `pulsar.broker.message.find.entry.read.size`: the entries and bytes read by the search, by reason and by the storage the ledger of the entry is read from (`bookkeeper`, `offloaded`).
It also states what is measured (a cursor reset to a timestamp and the message TTL lookups, not the `get-message-id` admin operation), that the metrics are per broker rather than per topic, and that entries served from the broker entry cache are included.
The metrics ship in Pulsar 5.0, which is not released yet, so the same section is added to `docs/` and to `versioned_docs/version-5.0.x/`.
