The Sensu System Check is a cross-platform Sensu Metrics Check that provides baseline system metrics in prometheus format.
| Name | Description |
|---|---|
| system_cpu_cores | Number of cpu cores on the system |
| system_cpu_idle | Percent of time cpu was idle1 |
| system_cpu_used | Percent of time cpu was used1 |
| system_cpu_user | Percent of time cpu was used by normal processes in user mode1 |
| system_cpu_system | Percent of time cpu used by processes executed in kernel mode1 |
| system_cpu_nice | Percent of time cpu used by niced processes in user mode1 |
| system_cpu_iowait | Percent of time cpu waiting for I/O to complete1 |
| system_cpu_irq | Percent of time cpu servicing interrupts1 |
| system_cpu_softirq | Percent of time cpu servicing software interrupts1 |
| system_cpu_stolen | Percent of time cpu serviced virtual hosts operating systems1 |
| system_cpu_guest | Percent of time cpu serviced guest operating system1 |
| system_cpu_guest_nice | Percent of time cpu serviced niced guest operating system1 |
Note 1: Metric tagged by cpu name with cpu-total meaning summed over all cpus on the system (Ex: cpu="cpu0", cpu="cpu-total")
| Name | Description |
|---|---|
| system_mem_used | Percent of memory used |
| system_mem_used_bytes | Used memory in bytes |
| system_mem_total_bytes | Total memory in bytes |
| Name | Description |
|---|---|
| system_swap_used | Percent of swap used |
| system_swap_used_bytes | Used swap in bytes |
| system_swap_total_bytes | Total swap in bytes |
| Name | Description |
|---|---|
| system_load_load1 | System load averaged over 1 minute, high load value dependant on number of cpus in system |
| system_load_load5 | System load averaged over 5 minute, high load value dependent on number of cpus in system |
| system_load_load15 | System load averaged over 15 minute, high load value dependent on number of cpus in system |
| system_load_load1_per_cpu | System load averaged over 1 minute normalized by cpu count, values > 1 means system may be overloaded |
| system_load_load5_per_cpu | System load averaged over 5 minute normalized by cpu count, values > 1 means system may be overloaded |
| system_load_load15_per_cpu | System load averaged over 15 minute normalized by cpu count, values > 1 means system may be overloaded |
| Name | Description |
|---|---|
| system_host_uptime | Host uptime in seconds |
| system_host_processes | Number of host processes |

Sensu Assets are the best way to make use of this plugin. If you're not using an asset, please consider doing so! If you're using sensuctl 5.13 with Sensu Backend 5.13 or later, you can use the following command to add the asset:
sensuctl asset add sensu/system-check
If you're using an earlier version of sensuctl, you can find the asset on the Bonsai Asset Index.
