Seen on a customer's SQL Server 2005 SP4 (legacy ODBC):
- agent-jobs declared @since with an initial value (2008+): "Incorrect syntax
near CONVERT" and SQLI-JOB-001/002 never ran. Now DECLARE; SET.
- plan-analysis used query_hash (2008+) and failed every 30 minutes for
SQLI-PLAN-001/002/003. On 2005 a statement is now identified by
sql_handle + offsets, as top SQL does. It needs sys.dm_exec_text_query_plan,
so the new capability TextQueryPlan (2005 SP2, 9.0.3042) is required.
- COM-DB-001 used OBJECT_SCHEMA_NAME (2005 SP2+); now joins sys.objects and
sys.schemas.
Audit of all collector SQL and community rules without minimumVersion 10.0:
the rest is 2005 syntax or behind a version/capability check.
Sql2005CompatibilityTests (2005 cannot run in CI): every collector that can
run on 2005 is scanned for 2008+ syntax in its SQL (inline DECLARE, +=,
MERGE, CONCAT/IIF/FORMAT/TRY_*, OFFSET/FETCH, date/time types, multi-row
VALUES), version-branched files listed explicitly; the same for community
rules; and the 2005 variants of plan analysis and top SQL must not use
query_hash. Verified to fail on the old agent-jobs SQL.

- Availability group collector (replica and database replica states,
queues, commit times) and rules: SQLI-AG-001 unhealthy/disconnected
replica or suspended data movement (scripts HADR RESUME), SQLI-AG-002
secondary behind (estimated data loss and redo time)
- SQL Agent collector using only granted msdb tables (no EXECUTE on msdb
functions): SQLI-JOB-001 failed job with the failing step's message
(backup/CHECKDB jobs are High), SQLI-JOB-002 SQL Agent not running
- Integration tests create a real availability group (CLUSTER_TYPE NONE)
and a failing job in the test container (HADR and Agent enabled)
