The system collector exposes system-wide metrics of the System performance counter object, such as context switches, system calls, processes and threads, and the system boot time.

Metric name prefix	system
Data source	Performance Counters
Enabled by default?	Yes

Flags

None

Metrics

Name	Description	Type	Labels
windows_system_boot_time_timestamp	Unix timestamp of last system boot, in whole seconds. Follows clock corrections	gauge	None
windows_system_context_switches_total	Total number of context switches	counter	None
windows_system_exception_dispatches_total	Total exceptions dispatched by the system	counter	None
windows_system_processes	Number of process contexts currently loaded or running on the operating system	gauge	None
windows_system_processes_limit	Maximum number of processes. Windows has no defined limit, so this is always reported as 4294967295	gauge	None
windows_system_processor_queue_length	Number of threads in the processor queue. There is a single queue for processor time even on computers with multiple processors.	gauge	None
windows_system_system_calls_total	Total combined calls to Windows NT system service routines by all processes running on the computer	counter	None
windows_system_threads	Number of Windows system threads	gauge	None

Example metric

Show current number of system threads

windows_system_threads{instance="localhost"}

Show current number of processes

windows_system_processes{instance="localhost"}
