Issue: 

The tomcat probe is generating critical alarms similar to the following:

The probe internal used memory 169792KB (136%) is >= 100.0% of 124000KB

 

Environment:  

tomcat (seen in all versions)

 

Cause: 

Probe is running out of java memory.

 

Resolution:

Deactivate the probe, then use the Raw Configure GUI to add a new <java_options> section under the top-level <properties> section:

<properties>
.....
java_home = .....
<java_options>
1 = -Xmx256m
</java_options>
<properties>

Also, change the <janitor> memorylimit to match the -Xmx size, noting that memory limit is in KB. So, in this case change memorylimit to 256000.

Activate the probe.

 

Additional Information:

Set the -Xmx to a value which is higher than the number reported in the alarm.
