The memory usage collected by the CDM probe that is installed on Non-Global Solaris zones appear collect values from Global zone and need confirmation on how the memory usage is being calculated within Non-Global Solaris zones.
See example below:
Global Zone total memory used is approx 92%+
Non-Global zones:
Global zone memstats output
All Non-Global zones Solaris instances generate CDM Memory Usage alarms for 95% threshold violation when their percent usage should be cummulative values that should equal the Global zone value.
Here are the alarm details for two (other two also report 95%) of the Non-Global zones:
Release : 20.1
Component : UIM - CDM WITH IOSTAT
The CDM probe does not have full support for Solaris Non Global zones. The zone probe should be considered for monitoring Solaris Non Global zones
