Zabbix uses Jstat automatic discovery to monitor Tomcat multiple instances

Use the JSTAT-GC TOMCAT ID to reorder the data into the $tomcat file, looping through
But jstat this command requires the same privileges as Tomcat to start the user Zabbix, you can start the zabbix-agent using the same user as the Tomcat startup user, or you can Visudo

# Apply Zabbix version 2.4.x to 3.0.3
# Auto Search jmx pid

# Automatic Discovery jmx monitoring. It applies only to JSTAT-GC pid it
