feat(obs): add bounded metrics dimensions (#5645)
* feat(obs): add drive topology detail metrics Expose additive drive info, topology, state, and per-drive API metrics while preserving the existing drive metric label sets. Backlog: rustfs/backlog#1655 Co-Authored-By: heihutu <heihutu@gmail.com> * fix(obs): preserve suspect drive runtime state Keep suspect as a bounded drive runtime state and avoid all-zero runtime_state samples for that storage health state. Co-Authored-By: heihutu <heihutu@gmail.com> * fix(obs): skip unknown drive inode samples Avoid exporting zero inode gauges for missing or stale drive snapshots and ignore zero-count API latency buckets. Co-Authored-By: heihutu <heihutu@gmail.com> * feat(obs): add scanner source work detail metrics Expose additive scanner source and cycle work metrics with bounded server/source/state labels while leaving the existing aggregate scanner metrics unchanged. Co-Authored-By: heihutu <heihutu@gmail.com> * feat(obs): add ilm action detail metrics Expose additive ILM action/state task metrics with a server label while preserving the existing aggregate ILM series. Co-Authored-By: heihutu <heihutu@gmail.com> * feat(obs): add delivery target server metrics Expose additive audit and notification delivery target metrics with server labels and extend removed-target tombstones for the server-aware series. Co-Authored-By: heihutu <heihutu@gmail.com> * feat(obs): add replication target flow metrics Expose additive bucket replication target sent and failed-flow metrics while preserving existing bucket aggregates and target backlog series. Co-Authored-By: heihutu <heihutu@gmail.com> * feat(obs): add request server metrics Expose additive API request metrics with server labels while preserving the existing request and traffic metric label sets. Co-Authored-By: heihutu <heihutu@gmail.com> * style(obs): apply rustfmt to metrics changes Apply rustfmt output to the metrics dimension changes without altering behavior. Co-Authored-By: heihutu <heihutu@gmail.com> * style(obs): reuse audit target label constant Use the exported audit target_id label constant for legacy audit target metrics. Co-Authored-By: heihutu <heihutu@gmail.com> * feat(obs): populate drive disk metrics Co-Authored-By: heihutu <heihutu@gmail.com> * feat(obs): add scanner bucket drive result metrics Co-Authored-By: heihutu <heihutu@gmail.com> * feat(obs): add replication proxy server metrics Co-Authored-By: heihutu <heihutu@gmail.com> * fix(obs): address metric liveness review Use checked division for drive API latency aggregation and keep recovered drive, scanner current-cycle, replication flow, audit target, and notification target series from retaining stale values. Co-Authored-By: heihutu <heihutu@gmail.com> * fix(obs): address metric dimension review Co-Authored-By: heihutu <heihutu@gmail.com> * fix(obs): address additional metric review Co-Authored-By: heihutu <heihutu@gmail.com> * fix(obs): count drive calls at start Co-Authored-By: heihutu <heihutu@gmail.com> * fix(obs): address metrics dimension review Co-Authored-By: heihutu <heihutu@gmail.com> * fix(metrics): address dimension review gaps Co-Authored-By: heihutu <heihutu@gmail.com> * fix(metrics): address scanner review follow-ups Co-Authored-By: heihutu <heihutu@gmail.com> * fix(metrics): address runtime review follow-ups Co-Authored-By: heihutu <heihutu@gmail.com> * fix(metrics): reduce disk metric contention Co-Authored-By: heihutu <heihutu@gmail.com> * fix(metrics): address runtime review follow-ups Co-Authored-By: heihutu <heihutu@gmail.com> * fix(metrics): retire stale dimension series Co-Authored-By: heihutu <heihutu@gmail.com> --------- Co-authored-by: heihutu <heihutu@gmail.com>
