How to change FglAM baseline jvm (java virtual machine) config options (4227474)

The JVM options used when the FglAM when it starts up can be changed in the Foglight console user interface (UI) and directly in the baseline.jvmargs.config file on the FglAM server.

Each line added to the JVM options will be incremented by one higher than the previous line.

Changing the JVM options using the Foglight console

1. Navigate to Administration | Agents | Agent Managers
   
2. Click on the Show Columns icon to the right of the Search box to add hidden columns that may not be enabled by default
3. Scroll to the bottom of the panel and enable the JVM Config column, then click the Apply button
   
4. Click on the JVM Config icon for the FglAM
5. Click on the Add VM Parameter button 
   
6. Add the VM Parameter and click the Save & Restart button
   
7. Confirm the change by clicking the OK button
   
8. The FglAM will be restarted in the background with the new setting

Changing the JVM options directly in the baseline.jvmarg.config file

1. From a command line (in Linux/Unix) or using Windows Explorer, navigate {FglAM location}\state\default\config
2. Look for the file named baseline.jvmargs.config
3. Edit the config file in a text editor (e.g., Vim, Pico, Microsoft Wordpad).
   Note: On Windows servers this file will be locked while the FglAM is running. The FglAM must be deactivated to save the file back to the server.
4. Look for the commented line Memory Settings near the bottom of the file
5. Add the new entries below this line in the format vmparameter.X = ""; where X is the next highest number after the previous entry, and the flag is entered between the quotes.
   An example with previous entries might be 
   vmparameter.0="-Xms21g";
   vmparameter.1="-Xmx21g";
   vmparameter.2="-Dagent.collector.schedule.load.max.delay.millis=300000";
   vmparameter.3="-Dcom.quest.connection.regulator.maxActiveConnectionsCap=1024";
   vmparameter.4="-Dsqlserver.driver.class.name=com.dell.dsgi.jdbc.sqlserver.SQLServerDriver";
   
   Note: When adding, modifying or removing Memory settings (-Xmx or -Xms) below, the resource negotiated settings config under the '/config/deployment' directory should be deleted prior to restart. This will allow for the changes to the memory config here applied in parallel with the resource negotiated deployment settings
6. Restart the FglAM agent Manager

Confirming the JVM options

Users can confirm that the JVM options were used by the FglAM when starting up by opening the latest copy of the FglAM log file after the restart and searching for the words "Adding VM parameter" and "from config file" to confirm that the new VM option has been added
