A one-minute collector reads open user transactions (age, log bytes used
and reserved, database, session, login, program, statement) and user
requests running longer than the threshold, leaving out the agent's own
and system sessions, BACKUP/RESTORE/DBCC (long operations) and requests
waiting on purpose. Transactions open a minute or holding 100 MB are kept
in insight.LongTransactions (migration 0014, RawDays).
Rules SQLI-TRAN-001 (open > 10 min, High at 6x), SQLI-TRAN-002 (> 1 GB
log) and SQLI-REQ-001 (statement > 15 min), configurable under
SQLInsight:Activity. Shown "right now" on the instance page and in the
time window analysis and PDF; GET /api/v1/instances/{name}/activity and
the analysis JSON leave logins and statements out.

A five-minute collector reads important error log entries from the best
source the agent's rights allow: the error log itself (xp_readerrorlog,
only with securityadmin), the default trace's ErrorLog and Audit Login
Failed events (optional ALTER TRACE), or the exception and connectivity
ring buffers (VIEW SERVER STATE: numbers and severity, failed logins).
Repetitions are summed per error; the watermark is the newest entry
read, because the default trace is buffered. Stored in
insight.ErrorLogEvents (migration 0013, EventDays), resumed after restart.
Rules SQLI-LOG-001..006: corruption 823/824/825, I/O over 15 s (833),
severe errors (17+), login failure bursts (configurable), stack dumps and
AG errors; rules needing the log text are "not measurable" with the
right to grant. Page /instanser/{navn}/fejllog (menu Overvågning) and
GET /api/v1/instances/{name}/error-log with messages redacted.

- Long operations: a one-minute collector reads operations with progress
from sys.dm_exec_requests (BACKUP, RESTORE, DBCC, REORGANIZE, SHRINK,
ROLLBACK): command, database, start, percent, expected end, login.
Stored in insight.LongOperations (migration 0011, RawDays), shown on
the instance page, in the time window analysis and its PDF. The last
10 durations per command and database survive restarts; SQLI-OPS-001
flags a backup/restore running over twice the median.
- Full-text community rules COM-FT-001..005 (metadata only, 2005 syntax):
disk-full or paused/throttled catalogs, stale manual/off change
tracking indexes and disabled indexes.
- Statement activity (CPU time / time in plan cache): column in top SQL
and SQLI-CPU-002 when above SQLInsight:TopSql:ActivityThresholdPercent
(default 50) for at least an hour. Never clears the plan cache.
- BuiltInCollectors.Create takes a CollectorSettings record.

Collects members of the fixed server roles and CONTROL SERVER every 15
minutes with login type, disabled state and SQL login password policy.
Windows groups are unfolded recursively through Active Directory on a
Windows agent (cached, 20 s timeout, failures shown with the reason).
Changes since the previous collection are logged, and who/when is read
from the default trace (event 108) when the agent has the optional
ALTER TRACE; authors that only reach the buffered trace later are filled
in at the next collection. The first collection is the baseline.
New rules SQLI-SEC-001 (new privilege, High for sysadmin/securityadmin/
CONTROL SERVER) and SQLI-SEC-002 (more sysadmins than the limit, default
3). Names are sensitive evidence and never in titles or subjects.
Web: /instanser/{navn}/rettigheder and /rettigheder with change log by
period, alert banner on the instance page and overview, and an audit
PDF (/rapporter/rettigheder.pdf) linked from Rapporter.

- new collector instance-config: collation, edition, version, services and
accounts (sys.dm_server_services, 2008 R2 SP1+), Instant File
Initialization and Lock Pages in Memory (where the build has the
columns), tempdb files, default paths; plus a fingerprint of the whole
setup (sp_configure, trace flags, services, version, tempdb files)
- changes are computed against the previous collection, which the agent
restores from the repository after a restart; migration 0008 keeps them
in insight.ConfigurationChanges (as long as resolved findings)
- SQLI-CFG-013 "Konfiguration ændret": information for a day when
sp_configure, a trace flag or a service account changes (account names
are sensitive evidence)
- page /instanser/{navn}/konfiguration: instance, CPU and memory, services,
tempdb, trace flags, non-default sp_configure (default vs. in use vs.
configured) and the change log; linked from the instance page
- the management report lists configuration changes in the period
- trace flag reading shared by trace-flags and instance-config

- Managed Instance reports 12.0.2000.8 but is evergreen: treated as the
newest engine with all capabilities; new SelfManagedInfrastructure
capability so backup, CHECKDB, files, tempdb, memory, patch level and
lifecycle rules report 'handled by Azure' instead of false findings
- Microsoft Entra ID login (managed identity, service principal, default
credential chain) via SqlConnection.AccessTokenCallback
- Least-privilege script recognizes Managed Instance; deadlock collector
falls back to the ring buffer when event files cannot be read
- Web UI shows the right release for Managed Instance
- README and installation docs: notifications and Managed Instance
- Catalog test: 61 rules with unique, well-formed ids
Integration suite green on SQL Server 2017 and 2022.
