0017_dynamics_ax adds insight.AxBatchRuns (completed batch runs, EventDays
retention) and insight.AxSequenceSamples (one NEXTREC/NEXTVAL sample per
sequence per day, HourlyDays retention). The agent reads them back after a
restart so job comparisons and forecasts continue, takes its thresholds from
SQLInsight:DynamicsAx, and only sends findings of the built-in SQLI-AX rules
to the hub for databases with the AX opt-in ticked; AX rule reasons (which
can name tables, logins and GRANT text) are replaced by a fixed text.

The agent mirrors SQLInsight:Instances into the repository at start (read-only
"fra konfigurationsfil" rows, every database monitored as before) and reads the
configuration on every tick: instances added, paused, removed or changed in
SQLInsight Web, and database choices, take effect without a restart. If the
repository cannot be read before the first load, the configuration file alone
is used.
AgentRequestService runs connection tests (with the permission check), database
discovery and instance discovery (SQL Server Browser, registry) as the agent's
own identity, and refreshes every instance's database list hourly. The agent
keeps an RSA key (DPAPI LocalMachine, restricted folder) and publishes its public
key and identity; SQL login passwords sealed by the web UI are opened only here.
Dynamics AX findings and AX rule outcomes are sent to SQLInsight Hub only for
databases where it is turned on (default off).

The index collector now sums index reads and writes between collections
across restarts of SQL Server (and of the agent, by seeding from the
stored snapshot) and keeps them per day in insight.IndexUsageDaily
(migration 0015, HourlyDays). SQLI-IDX-002 judges an index once it has
been followed for 7 days instead of needing 7 days of uptime.
GET /api/v1/instances/{name}/index-usage lists usage per index.
SQLI-STAT-001 also reports statistics that were never updated on tables
with rows; statistic rows now come from the table's heap or clustered
index, as a never-updated statistic has no row count of its own.

A five-minute collector reads tempdb space (free, version store, user and
internal objects, whether files can grow), the 'Version Store Size (KB)'
counter, the sessions using most tempdb, the oldest snapshot transaction
and, only when the version store is large, the databases generating
versions. Trend and heavy sessions survive restarts; used space and the
version store become metrics with explanation and assessment.
Rules SQLI-TEMP-001 (version store > 1 GB or steadily growing),
SQLI-TEMP-002 (nearly full and cannot grow) and SQLI-TEMP-003 (session
above 1 GB for 15 minutes), configurable under SQLInsight:Tempdb.
"tempdb lige nu" on the instance page; GET /api/v1/instances/{name}/tempdb.

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.

A new light collector samples sys.dm_exec_requests every 15 seconds:
waiting user sessions (not the agent's own) by wait type, database and
statement (same key as top SQL), with blocking. Sampling-only cycles
reuse the last probe and skip rule evaluation. Stored in
insight.ActiveWaitSamples (migration 0010) for RawDays.
Wait types on the instance page and in the analysis link to
/instanser/{navn}/ventetyper/{type}: Danish explanation from a new
knowledge base (shared with the SQLI-WAIT rules, with Dynamics AX notes),
trend over time, the statements that waited with share and estimated
wait, a link to the full text (/instanser/{navn}/sql) and, for lock
waits, to blocking in the same window. SQL Server 2005 compatible.

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

On SQL Server 2005 twenty rules stood as "not measurable" (Query Store,
system_health, memory columns …) between the real gaps, and counted in the
overview's "regler ikke målbare". They are not gaps: the version simply
lacks what they look at.
- New RuleOutcome.NotApplicable (last in the enum: outcomes are stored as
numbers, so existing rows keep their meaning).
- A rule or collector missing only capabilities inherent to the instance
(version-gated, plan cache memory columns, or Azure-managed) is not
applicable, with the version each needs: "Ikke relevant for SQL Server
2005: kræver QueryStore (fra SQL Server 2016)". Missing settings or rights
(HADR not enabled …), collector failures and permission errors stay
"not measurable". CollectedData.MarkNotApplicable carries this from
collectors to the rules that use their data; community rules below their
minimumVersion are not applicable too.
- Counts are unchanged in shape: the overview, KPI, JSON API and Prometheus
count outcomes 2 and 3 only. The instance page lists the rest in a
collapsed "Ikke relevant for SQL Server 2005 (n)" (details/summary, no
JS) after the real gaps. Report controls whose core rule does not apply
count neither as met nor as not measured.
Tests: engine (version vs. setting vs. collected data), inherent
capabilities, the existing version tests now expect not applicable, report
control status, and the web page and overview count.

- Evidence can be marked sensitive (query text, logins, hosts, programs,
job error messages); rules mark it. Sensitive values and the server
name are sent as [udeladt] unless the customer allows them.
- Full-state submission contract (all active findings and rule outcomes
per instance), idempotent by submission id
- Local outbound queue in the repository (migration 0002): newest state
per instance only, exponential backoff up to an hour, permanent
rejections (bad license, bad request) are given up, sent items purged
- Hub status (license state, last sent, last error) for the web UI
- Sync runs only with a valid license (or in grace); monitoring never
depends on it

- Repository reports which findings opened and resolved per evaluation
- Agent notifies on new and resolved findings and on instance
unreachable/recovered transitions, with links to the web UI
- Channels: e-mail (MailKit, HTML-encoded), Microsoft Teams Workflows
webhook (Adaptive Card), generic JSON webhook signed with HMAC-SHA256
- Per-channel minimum severity (outages always sent), one message per
batch, hourly cap per channel; a failing channel never stops monitoring
- Tested with a real SMTP server (Mailpit) and the real agent pipeline

Baselines per hour of the week (with neighbouring hours) from four weeks
of hourly aggregates, computed in C# (independent of DATEFIRST) and
refreshed by the agent each hour. SQLI-ANOM-001 compares current load
with what is normal at this time: CPU far above normal, batch requests
far above or collapsed (application down?), page life expectancy
collapse. Not measurable until enough history exists.

- ASP.NET Core Blazor static SSR: overview with KPI tiles, instance page
(findings, CPU/batch/PLE trends, top waits, file latency, blocking,
deadlocks with .xdl download, not-measurable rules, resolved), finding
detail with explanation, evidence, fix script and references
- Light-first design (sidebar, cards, self-hosted Inter, teal accent),
optional dark theme via toggle; strict CSP, no inline styles
- Windows authentication (Negotiate/IIS) with optional group restriction;
refuses to run without authentication outside Development
- Hosting: IIS (in-process ASP.NET Core Module), Windows service with
Kestrel, or systemd; web reads the repository with db_datareader only
- docs/installation.md for repository, permissions, agent and web
- Fix: CPU used by other processes is not derived on Linux (SystemIdle is
unreliable there); deadlocks are not re-reported or stored twice after
an agent restart; Dapper sends datetime2 so time comparisons are exact

Each instance runs its due collectors over one hardened connection per
cycle, keeps previous results for deltas, evaluates all rules and stores
findings, rule states and time series. Instances run in parallel with a
limit; a slow or failing instance never delays the others. The
repository is migrated at startup with retry, and maintenance runs hourly.
End-to-end test against SQL Server with the least-privilege login.
