Last updated on JANUARY 30, 2020

Applies to:

APM - Application Performance Management - Version 12.1.0.7.0 to 13.2.3.0.0 [Release 12.1 to 13.2]
Information in this document applies to any platform.

Symptoms

Memory usage
In the linux process list it is seen that the process logr process consumes a lot of memory.
This varies from a few GB up to 8GB. An example ps command output of the logr process:

# ps auwx|head -n 1;ps auwx |grep logr|grep -v grep
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
501 17230 0.0 0.2 62616 11108 ? Ss Jan29 0:02 logr run
501 17234 0.1 1.5 3333560 65332 ? Sl Jan29 9:44 logr run

In the above example the logr process takes 3.3GB memory

Core dumps
When logr runs out of memory it will create core dumps. These are files which tell the last set of actions the process did before exiting. You will find mention of such an event in:

$RUEI_DATA/processor/log/_default/YYYYMMDD.log
$RUEI_DATA/processor/log/wg/YYYYMMDD.log

You can also find this even in the Event Log of the GUI
