Swap Usage
More information about swap space usage thresholds
The Swap Usage service checks swap space usage on each node and generates an alert if:
- For MGMT and MDS nodes: free swap space is less than the threshold values
- For OSS nodes: used swap space is greater than the threshold values
Default Thresholds
| Node | Status | Thresholds |
|---|---|---|
| MGMT and MDS | Warning | 50% free swap space |
| Critical | 30% free swap space | |
| OSS | Warning | 99% swap space used |
| Critical | 50% swap space used |
Metrics: Used swap space in MB is returned.
Status Information Examples
Example for MGMT Node Where Status is OK
Status Information: SWAP OK - 100% free (36327 MB out of 36327 MB) Performance Data: swap=36327MB;18163;10898;0;36327
Example for OSS Node Where Status is OK
Status Information: SWAP OK - 100% free (16383 MB out of 16383 MB) Performance Data: swap=16383MB;16220;8191;0;16383
