weblogic_server_reports_target_has_encountered_metric_evaluation_errors_in_grid
Problem
The WLS targets report having metric evaluation errors and the agent log files are full of errors (and filling up rapidly)
Diagnosis
- Check the logfiles:
In the $AGENT_HOME/sysman/log directory, check the file: emagent.trc
If you see this repeated 1000's of times, we can fix it!

Solution
- Backup emd.properties in $AGENT_HOME/sysman/config
- Stop the agent:
cd $AGENT_HOME/bin ./emctl stop agent
- Edit emd.properties to add these memory attributes to the agentJavaDefines line:
agentJavaDefines=-Xms256m -Xmx512m ...rest of original line
- Restart the agent:
./emctl start agent
- Force an upload to the Grid:
./emctl upload agent
Go back to the Grid homepage and admire more green!
