…#325) Collectors that iterate databases and USE/query into them now exclude AG secondary replicas configured with READ_ONLY connections, which reject non-read-intent sessions with "not accessible for queries" errors. Filter uses sys.availability_replicas.secondary_role_allow_connections_desc to identify secondaries that won't accept our connection type. Databases on primaries, non-AG databases, and secondaries with ALL connections continue to be collected normally. Changed locations: - install/39_collect_database_configuration.sql (scoped config cursor) - install/09_collect_query_store.sql (QS discovery cursor) - Lite/RemoteCollectorService.ServerConfig.cs (scoped config db list) - Lite/RemoteCollectorService.QueryStore.cs (QS discovery cursor) Clean install verified on sql2016 with zero errors.
