service collector

The service collector exposes metrics about Windows Services

Metric name prefix	service
Classes	none
Enabled by default?	Yes

Flags

--collector.service.include

Regexp of service to exclude. Service name (not the display name!) must both match include and not match exclude to be included. Recommended to keep down number of returned metrics.

--collector.service.exclude

Regexp of service to include. Process name (not the display name!) must both match include and not match exclude to be included. Recommended to keep down number of returned metrics.

Metrics

Name	Description	Type	Labels
windows_service_info	Contains service information run as user in labels, constant 1	gauge	name, display_name, path_name, run_as
windows_service_start_mode	The start mode of the service, 1 if the current start mode, 0 otherwise	gauge	name, start_mode
windows_service_state	The state of the service, 1 if the current state, 0 otherwise	gauge	name, state
windows_service_process	Process of started service. The value is the creation time of the process as a unix timestamp	gauge	name, process_id

States

A service can be in the following states:

• stopped
• start pending
• stop pending
• running
• continue pending
• pause pending
• paused
• unknown

Start modes

A service can have the following start modes:

• boot
• system
• auto
• manual
• disabled

Note that there is some overlap with service state.

Run As

Account name under which a service runs. Depending on the service type, the account name may be in the form of "DomainName\Username" or UPN format ("Username@DomainName").

Alerting examples

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: windows_service_state{instance="SQL",name="sqlserveragent",state="running"} == 0
    for: 3m
    labels:
      severity: high
    annotations:
      summary: "Service {{ $labels.name }} down"
      description: "Service {{ $labels.name }} on instance {{ $labels.instance }} 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: windows_service_state{instance="SQL",name="mssqlserver",state="running"} == 0
    for: 3m
    labels:
      severity: high
    annotations:
      summary: "Service {{ $labels.name }} down"
      description: "Service {{ $labels.name }} on instance {{ $labels.instance }} has been down for more than 3 minutes."

In this example, instance is the target label of the host. So each alert will be processed per host, which is then used in the alert description.
