HOW TO DISABLE CPU UTILIZATION (%), MEMORY UTILIZATION (%) AND SWAP UTILIZATION (%) METRICS IN ENTERPRISE MANAGER CLOUD CONTROL (12c, 13c)
ISSUE
A message looks like:
Host=dbpilot.net
Target type=Host
Target name=dbpilot.net
Categories=Capacity
Message=Memory Utilization is 95.145%, crossed warning (80) or critical (95) threshold.
Severity=Critical
Event reported time=Jul 24, 2018 8:21:22 PM NOVT
Operating System=Linux
Platform=x86_64
Associated Incident Id=58720
Associated Incident Status=New
Associated Incident Owner=
Associated Incident Acknowledged By Owner=No
Associated Incident Priority=None
Associated Incident Escalation Level=0
Event Type=Metric Alert
Event name=Load:memUsedPct
Metric Group=Load
Metric=Memory Utilization (%)
Metric value=95.145
Key Value=
Rule Name=PRODGROUP,EVENTS
Rule Owner=SYSMAN
Update Details:
Memory Utilization is 95.145%, crossed warning (80) or critical (95) threshold.
Incident created by rule (Name = Incident management rule set for all targets, Create incident for critical metric alerts [System generated rule]).
REASON
SOLUTION
There are 2 options to stop generating this type of the alert, either by increasing a threshold value for a metric or by disabling the load metric collection.
Option 1: Increase the “Warning Threshold” and the “Critical Threshold” on the “Metric and Collection Settings” page for the “Memory Utilization (%)” metric
Navigate to Targets => Hosts
Query your host in “Search” text box => click on a host link
On a host page navigate to Hosts => Monitoring => Metric and Collection Settings
Set a value you want for the threshold and click “OK“. The Warning threshold must be less than the Critical threshold, they can’t have the same value.
Click “OK” on the confirmation page
NOTE: The same actions are used to modify others thresholds, like the CPU Utilization (%) or the Swap Utilization (%).
Option 2: Disable the CPU Utilization (%), the Memory Utilization (%) and the Swap Utilization (%) load metrics collection in Enterprise Manager Cloud Control
Open the “Metric and Collection Settings” page (see option 1 for details) and click the link at “Collection Schedule” column for the Load metric
On the opened page click the “Disable” button in the “Collection Schedule” section and than click the “Continue” button to modify settings
Click the “OK” button to receive confirmation of the update
Confirm that the “Collection Schedule” is disabled
