As described in Viewing cluster utilization, by default warning alerts are generated when the cluster utilization reaches 60% of capacity, and critical alerts are generated when the cluster utilization exceeds 85% of capacity.
You can change the levels at which warning and critical alerts will be generated. The warning level cannot be set to a higher value than the critical level.
To change the warning level:
Log in to the Central Management CLI.
Go to CLI configuration mode:
cm-hostname > enable cm-hostname # configure terminalSpecify the percentage:
cm-hostname (config) # cmc mvx status cluster-sizing threshold warning <percentage>where
percentagecan be a value from 10–90 and must be less than the "critical" percentage.Verify your change:
cm-hostname (config) # show cmc mvx status cluster-sizing configSave your change:
cm-hostname (config) # write memory
To change the critical level:
Log in to the Central Management CLI.
Go to CLI configuration mode:
cm-hostname > enable cm-hostname # configure terminalSpecify the percentage:
cm-hostname (config) # cmc mvx status cluster-sizing threshold critical <percentage>where
percentagecan be a value from 20–100 and must be a greater than the "warning" value.Verify your change:
cm-hostname (config) # show cmc mvx status cluster-sizing configSave your change:
cm-hostname (config) # write memory
Example
The following example changes the warning level to 75% of total capacity.
cm-1 (config) # cmc mvx status cluster-sizing threshold warning 75
cm-1 # show cmc mvx status cluster-sizing config
MVX Cluster Sizing Configurations:
Enabled : yes
Utilization Warning Threshold : 75%
Utilization Critical Threshold : 95%
