This metric shows RAM usage statistics.
This scope has no labels.
Metrics:
| Metric | Dimensions | Unit |
|---|---|---|
| system.ram | free, active, inactive, wired, cache, laundry, buffers | MiB |
| mem.available | avail | MiB |
Alerts
The following alerts are available:
| Alert name | On metric | Description |
|---|---|---|
| ram_in_use | system.ram | system memory utilization |
| ram_in_use | system.ram | system memory utilization |
| ram_available | mem.available | percentage of estimated amount of RAM available for userspace processes, without causing swapping |
| ram_available | mem.available | percentage of estimated amount of RAM available for userspace processes, without causing swapping |
