Level: Critical

Purpose: Identify when one of the Errigal Grails Application is using an excessive amount of heap memory for a defined duration of time.

Scenario: ReportingManager on EXTApps2 used more than 90% of its Heap for 120s. Typical reason in this instance would be a rogue report run with very broad input variable e.g a trap report specifying range of over year.

Resolution: Monitor to see if heap usage is reducing. If not and it becomes evident that the application will run out of memory, perform a restart of the application.

Manual Action Steps:
Script Based Restart

cd /var/tomcat/ReportingManager/bin/
./shutdown.sh
ps aux | grep -i Reporting 
(Kill process if still running: kill $pid)
./startup.sh

Ansible Based Restart

ansible-playbook -i ../env-configuration/${env}/hosts.ini --diff --vault-id @prompt reportingmanager.yml -e "actions='stop,start'" --limit $appHandler

Auto Clear: Yes
