The following components of wildfly are monitored through this script collection:
- host controller
- process controller
- slave100
- slave200
where slave100 and slave200 are the names of the two servers configured on the monitored host. While a more generic approach to server monitoring would be certainly a good idea, I won't be able to provide it due to time constraints. I will happily accept patches that do though.
In order to work this collection of scripts require the use of a zabbix_agent.d configuration (/etc/zabbix/zabbix_agentd.d/userparameter_jvm.conf) as follows:
# JVM user parameter
UserParameter=jvm.processcontroller.running[*],/opt/jvm-monitor/monitor-jvm.sh "$1"
UserParameter=jvm.processcontroller.limittrapstarter[*],/opt/jvm-monitor/monitor-jvm-limits.sh "$1"
The script collection has been tested on CentOS 6, 7 and SmartOS using an Oracle 1.7 jdk and Oracle 1.8 jdk. Some script pathes are hardcoded due to timeconstraints which implies that the scripts in their current state have to be located in the folder /opt/jvm-monitor.
Look into the head section of both monitor scripts to find debug options.
The following execution will return the data that would be send to zabbix to the console for review:
./monitor-jvm.sh /etc/zabbix/zabbix_agentd.conf true
./monitor-jvm-limits.sh /etc/zabbix/zabbix_agentd.conf true
The following commands will generate data and send it to the zabbix trapper.
zabbix_get -s jvm.host.ip -k jvm.processcontroller.running["/etc/zabbix/zabbix_agentd.conf"]
zabbix_get -s jvm.host.ip -k jvm.processcontroller.limittrapstarter["/etc/zabbix/zabbix_agentd.conf"]
If the later doesn't yield any results despite not generating any error, set DEBUG=true in the head section of monitor-jvm.sh and monitor /tmp/jvm-monitor.log.
These scripts are provided as is and come with no warranty and no further documentation. They can't be deployed and run out-of-the-box. You will need to be familiar with wildfly, bash and zabbix to make use of it. They weren't intended for public release when written. I've published them upon request by: https://issues.jboss.org/browse/WFCORE-974#
