Foglight Agent Manager runs out of memory (4252696)

Foglight Agent Manager (FglAM) process stops with the following error message:

ERROR [HttpDownstream-67 - /catalyst-glue-service/message/message] com.quest.glue.core.util.CommonsLoggingToQuestBridge - Error for /catalyst-glue-service/message/message
java.lang.OutOfMemoryError: Java heap space

The Foglight Agent Manager does not have sufficient memory allocated to support the agents running on it.

If the error java.lang.OutOfMemoryError: Java heap space appears, memory allocation for the FglAM JVM may need to be increased. By default, the FglAM is configured to allow the JVM Heap minimum 22mb and maximum 256mb.

Please refer to specific cartridge documentation for a "Parameters Used for Hardware Sizing" section based on the particular FMS and cartridge version as recommendations can change. It is also recommended to allocate more heap memory to allow for future agent expansion and adding physical RAM to the FglAM host OS to allow for the allocation to successfully occur.

To increase the values, follow the steps below:

1. Go to the FglAM directory $FGLAM_HOME/state/default/config/
2. Make a backup copy of the file baseline.jvmargs.config
3. Now open it up for editing. At the end of the file, there are entries that are commented from use:

   #vmparameter.0 = "";
   #vmparameter.1 = "";

   Remove the comment # from each line and add the values between the quotation marks; this example sets the min=1024mb and max=1024mb.

   vmparameter.0 = "-Xms1024m";
   vmparameter.1 = "-Xmx1024m";

   NOTE: If the parameters are already in use for a different setting, use the next number in the sequence, for example vmparameter.2 and vmparameter.3

4. Save the file edits.
5. Delete directory $FGLAM_HOME/state/default/config/deployment as it may prevent new values to be used. This will be re-created once the FglAM is restarted.
6. Restart the FglAM.

To confirm changes, review the log file $FGLAM_HOME/state/default/logs/FglAM_YYYY-MM-DD_hhmmss_001.log and search for "VM options" to verify the new values; for example:

VM Options:
...
-Xmx1024m
-Xms1024m
