ems probe creating very large log files

Products

• DX Unified Infrastructure Management (Nimsoft / UIM)

Issue/Introduction

The ems probe does not appear to be rolling log files correctly and is creating huge files.

Environment

• DX UIM - Any Version (see note regarding 23.4.6 and earlier below)
• ems probe

Resolution

1. Open the Raw Configure interface for the ems probe
2. inside the "setup" section, ensure that youhave the follwing key/value:
   
   key: log4j
   value: true
   
   
   
   
3. Navigate to the startup->opt section
4. Edit the "java_opts" key and ensure that it contains the following value:
   -server -Dlog4j.configurationFile=file:./log4j2.xml -XX:ErrorFile=./hs_err_pid.log
   
   
   
   
   Note for UIM 23.4.6 and earlier:
   In addition to the above steps,   edit the file (UIM_HOME)\Nimsoft\probes\service\ems\log4j2.xml using a text editor such as Notepad++ and find the value for "Root level" as seen in the below screenshot.  Make sure this is set to one of the following values:
   
   "all", "trace", or "debug" 
   
   Due to a defect, if you use the values "info", "warn", "error", "fatal", or "off" this will cause the log file to grow indefinitely.  (This will be resolved in DX UIM 23.4.7 - ETA March 2026)
