@ -66,10 +66,42 @@ A service can have any of the following statuses:
Note that there is some overlap with service state.
### Example metric
_This collector does not yet have explained examples, we would appreciate your help adding them!_
Lists the services that have a 'disabled' start mode.
```
wmi_service_start_mode{exported_name=~"(mssqlserver|sqlserveragent)",start_mode="disabled"}
```
## Useful queries
_This collector does not yet have any useful queries added, we would appreciate your help adding them!_
Counts the number of Microsoft SQL Server/Agent Processes
```
count(wmi_service_state{exported_name=~"(sqlserveragent|mssqlserver)",state="running"})
```
## Alerting examples
_This collector does not yet have alerting examples, we would appreciate your help adding them!_
**prometheus.rules**
```
groups:
- name: Microsoft SQL Server Alerts
rules:
# Sends an alert when the 'sqlserveragent' service is not in the running state for 3 minutes.
- alert: SQL Server Agent DOWN
expr: wmi_service_state{name="SQL",exported_name="sqlserveragent",state="running"} == 0
for: 3m
labels:
severity: high
annotations:
summary: "Service {{ $labels.exported_name }} down"
description: "Service {{ $labels.exported_name }} on instance {{ $labels.name }} has been down for more than 3 minutes."
# Sends an alert when the 'mssqlserver' service is not in the running state for 3 minutes.
- alert: SQL Server DOWN
expr: wmi_service_state{name="SQL",exported_name="mssqlserver",state="running"} == 0
for: 3m
labels:
severity: high
annotations:
summary: "Service {{ $labels.exported_name }} down"
description: "Service {{ $labels.exported_name }} on instance {{ $labels.name }} has been down for more than 3 minutes."
```
In this example, `name` is the target label of the host. So each alert will be processed per host, which is then used in the alert description.
