dynamics-ax (hourly) lists the monitored AX databases with version, schema,
companies and read access; discovery and the AX community rules (now marked
dynamicsAx) use the same detection. dynamics-ax-batch (5 min) reads BATCH
(3.0/4.0) or BATCHJOB/BATCHJOBHISTORY (2009+), keeps each job's own run
history; dynamics-ax-sequences (hourly) reads NUMBERSEQUENCETABLE and
SYSTEMSEQUENCES and forecasts from SQLInsight's own daily samples. All reads
run through [db].sys.sp_executesql under read committed with a 2 s lock
timeout (snapshot when allowed), bounded with TOP, never NOLOCK, never
written. Blocking now captures CONTEXT_INFO for the AX user mapping.

Collectors (SQL Server 2000+, version-specific SQL, least privilege):
server, configuration, trace flags, databases (settings, backups in UTC,
CHECKDB, VLFs, Query Store, files, tempdb), suspect pages, plan cache,
wait stats and file I/O as deltas with restart/clear detection,
performance counters, CPU from the scheduler monitor ring buffer,
blocking (sleeping head blockers with open transactions), and deadlocks
from system_health continuing from the last file offset.
Rules: configuration (memory, MAXDOP per Microsoft NUMA guidance, cost
threshold, ad hoc bloat, risky options, pending changes), databases
(state, settings, backups, log backups, CHECKDB, suspect pages, VLFs,
autogrowth, max size, Query Store, tempdb), waits (THREADPOOL, signal
waits, locks, I/O, WRITELOG, parallelism, PAGELATCH), I/O latency, CPU,
memory grants, blocking and deadlocks. Missing data makes a rule not
measurable with the collector's reason.
Integration tests run every collector as the least-privilege login and
reproduce real blocking and a real deadlock; green on 2017 and 2022.
