The collector reads the SQL Server performance objects (`Access Methods`,

`Buffer Manager`, `Databases`, `Locks`, `Wait Statistics` and others) with

`pdh.CounterTypeRaw`, one PDH collector per SQL Server instance. It needs a

SQL Server Database Engine. CI provisions SQL Server Express (instance
|
||||
`CISQL`, database `CIWindowsExporter`) and lists `mssql` in
|
||||
`WINDOWS_EXPORTER_TEST_COLLECTORS`, so live tests must fail there instead of
|
||||
skipping. Express has no availability groups. These notes were

`Cumulative wait time (ms) per second`, `Waits in progress` and

`Waits started per second`. All counters are
|

`PERF_COUNTER_LARGE_RAWCOUNT`, so the meaning comes from the instance name.
|

All values stayed 0 over 10 seconds on this idle instance.
|

SQL Server recomputes every item about every 5 seconds over its last
|

interval. Under lock contention, `Waits started per second` showed 5 and
|
||||
then 0 while `sys.dm_os_wait_stats` kept growing, so all items are gauges.
|
||||
- `Buffer cache hit ratio` (`PERF_RAW_FRACTION`) is windowed as well: value
|
||||
and base are the page lookups of the last refresh, so it is a gauge.
|
||||
`Worktables From Cache Ratio` has a growing base and is a running total.
|
||||
- `TestMetricTypesMatchCounterTypes` compares the published types with

`pdh.Collector.MetricType` against a live instance; deliberate exceptions

(`Log Growths`, `Log Shrinks`, `Log Truncations`) are listed there.
