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

NodeStatusThresholds
MGMT and MDSWarning50% free swap space
Critical30% free swap space
OSSWarning99% swap space used
Critical50% 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
