* [MM-71058] Add the search health rules Ports the Elasticsearch / OpenSearch checks: localhost ConnectionURL in a cluster, a failed connection test, post-count scale thresholds, live indexing batch size, unsupported major version, missing analysis-icu plugin, and skipped TLS verification. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> Co-authored-by: Cursor <cursoragent@cursor.com> * [MM-71058] Cover the search rules in the packet fixtures The fixtures had no ElasticsearchSettings or search diagnostics, so the search rules could only report unknown offline. Standalone now runs with indexing off; HA runs OpenSearch with an upgraded LiveIndexingBatchSize of 1. The mmctl test packet gets the search data every real packet has. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> Co-authored-by: Cursor <cursoragent@cursor.com> * [MM-71058] Use the shared reasons in the search rules The post count and the leader's search diagnostics are plain missing sources, so they report the shared stats and diagnostics reasons instead of per-code strings. The version rule keeps its own reason, now only for an unrecognized backend or version, and the ICU rule keeps its reason for a plugin list skipped because the version could not be read. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> Co-authored-by: Cursor <cursoragent@cursor.com> * [MM-71058] Share the indexing gate across the search rules Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * [MM-71058] Tighten the search rule edge cases Report an uncollected cluster version as unavailable, mask passwords containing '@', treat batch sizes <= 1 as synchronous, and flag unspecified addresses as local. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * [MM-71058] Fire the search scale rules above the post thresholds Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com> * Add SEARCH_UNAVAILABLE rule and no-fallback ES_SERVER_ERROR message SEARCH_UNAVAILABLE fires when SqlSettings.DisableDatabaseSearch is on and Elasticsearch searching is off, so searches silently return nothing. ES_SERVER_ERROR now says search is fully down when there is no database fallback. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> * [MM-71058] Lower ES_MISSING_ICU to info and drop the batch size default The plugin list is advisory and cannot prove a plugin is absent, so the missing ICU finding is informational until per-node plugin data exists. * [MM-71058] Avoid duplicate search findings and simplify the search rules The scale rules resolve when database search is disabled, and ES_SERVER_ERROR uses the no-fallback message only while Elasticsearch serves search, so SEARCH_UNAVAILABLE alone reports a fully disabled search. The loopback check also matches localhost. and *.localhost. * [MM-71058] Split the unsupported search version message by direction Upgrading the search cluster is the wrong advice when it is newer than the supported range, so the finding message now says whether the cluster is too old or too new, and the remediation is direction-neutral. --------- Co-authored-by: Claude Opus 5.5 (1M context) <noreply@anthropic.com> Co-authored-by: Cursor <cursoragent@cursor.com>
