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.

|
| 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](https://en.wikipedia.org/wiki/Context_switch) | 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](https://en.wikipedia.org/wiki/Thread_(computing)) | 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"}
|
|
```
|
|
|
|
## Useful queries
|
|
Find hosts that have rebooted in the last 24 hours
|
|
```
|
|
time() - windows_system_boot_time_timestamp < 86400
|
|
```
