Set the QuerySurge Agent Memory Allocation on Linux

Versions: 8.0+

Set the QuerySurge Agent Memory Allocation (Linux)

1. Make sure the Agent is not executing. You can do this by logging into QuerySurge and checking the Agent status.
   
   
2. Log into the QuerySurge Agent box either as root or as a sudoer (or equivalent).
   
   
3. On the QuerySurge Agent box, stop your QuerySurge Agent with following command:
   
   service QuerySurge stop agent
   
   
4. Navigate to the QuerySurge /agent/config directory, which is found at:
   /<QuerySurge Install Dir>/QuerySurge/agent/config  - with the default install location, this is in: /opt/QuerySurge/agent/config
   
   
5. Make a backup copy of the file agentconfig.xml using the following command:
   cp agentconfig.xml agentconfig.xml.bak
   
   
6. Edit the agentconfig.xml file with a text editor. Look for the <heap> tag, which by default looks like:
   <heap>1000</heap>
   
   This means 1000MB heap request for the Agent (this is the default size). Edit the heap size to change it to the desired value.
   
   Example: If you want to change the agentconfig.xml to set the Agent heap to 3000MB, the tag should look like: <heap>3000</heap>
   
   
7. Make sure that you have not accidentally changed the XML so that it is invalid. Save the file. Start the QuerySurge services using the following command:
   
   service QuerySurge start agent
   
   
8. If you have mis-edited the agentconfig.xml file, the Agent will most likely be unable to start. If it fails to start, check the file. (You can always revert to your backup copy.)
   
   
9. If you have other QuerySurge Agents deployed on other boxes, they should be configured with the same value, if possible.
