### Example metric
|
||||
|
||||
@@ -288,16 +290,32 @@ windows_mssql_bufman_buffer_cache_hits{instance="host:9182", mssql_instance="MSS
|
||||
windows_mssql_bufman_buffer_cache_lookups{instance="host:9182", mssql_instance="MSSQLSERVER"}
|
||||
```
|
||||
|
||||
This principal can be used for following metrics too:
|
||||
- AccessMethodsWorktablesFromCacheHitRatio
|
||||
- accessmethods_worktables_from_cache_hits
|
||||
- accessmethods_worktables_from_cache_lookups
|
||||
- LogCacheHitRatio
|
||||
- databases_log_cache_hits
|
||||
- databases_log_cache_lookups
|
||||
- AverageLockWaitTime
|
||||
- locks_wait_time_seconds
|
||||
- locks_count
|
||||
SQL Server refreshes both values every few seconds with the hits and lookups of the last interval, so they are gauges and need no `rate()`.
|
||||
The same applies to `databases_log_cache_hits` and `databases_log_cache_lookups`.
|
||||
|
||||
### Ratios and averages of running totals
|
||||
|
||||
The Worktables From Cache Ratio, Average Wait Time (ms), XTP Controller DLC Latency/Fetch and Update conflict ratio counters are running totals.
|
||||
Divide the rates of numerator and base:
|
||||
|
||||
```
|
||||
# Worktables From Cache Ratio
|
||||
rate(windows_mssql_accessmethods_worktables_from_cache_hits[5m]) / rate(windows_mssql_accessmethods_worktables_from_cache_lookups[5m])
|
||||
|
||||
# Average lock wait time in seconds
|
||||
rate(windows_mssql_locks_wait_time_seconds_total[5m]) / rate(windows_mssql_locks_count_total[5m])
|
||||
|
||||
# Average XTP controller DLC latency per fetch in seconds
|
||||
rate(windows_mssql_databases_xtp_controller_dlc_fetch_latency_seconds_total[5m]) / rate(windows_mssql_databases_xtp_controller_dlc_fetches_total[5m])
|
||||
|
||||
# Update conflict ratio
|
||||
rate(windows_mssql_transactions_update_conflicts_total[5m]) / rate(windows_mssql_transactions_update_snapshot_transactions_total[5m])
|
||||
```
|
||||
|
||||
### Wait statistics
|
||||
|
||||
Each `windows_mssql_waitstats_*` metric is a wait type. The `item` label names the statistic: `Average wait time (ms)`, `Cumulative wait time (ms) per second`, `Waits in progress` and `Waits started per second`.
|
||||
SQL Server computes them over its most recent sampling interval, so they are gauges. Values of the `(ms)` items are in milliseconds.
