NAME

zabbix-java-gateway.jar - Zabbix Java/JMX monitoring agent.

USAGE

/etc/init.d/zabbix-java-gateway [ start|stop|restart|status ]

DESCRIPTION

"Zabbix Java gateway" is a daemon to collect information from JMX agent. When Zabbix
server wants to know the value of a particular JMX counter on a host, it asks Zabbix Java
gateway, which uses the JMX management API to query the application of interest remotely.
The application does not need any additional software installed, it just has to be started
with "-Dcom.sun.management.jmxremote" option to Java on the command line.

Java gateway accepts incoming connection from Zabbix server or proxy and can only be used
as a "passive proxy". As opposed to Zabbix proxy, it may also be used from Zabbix proxy
(Zabbix proxies cannot be chained). Access to each Java gateway is configured directly in
Zabbix server or proxy configuration file, thus only one Java gateway may be configured
per Zabbix server or Zabbix proxy. If a host will have items of type JMX agent and items
of other type, only the JMX agent items will be passed to Java gateway for retrieval.

When an item has to be updated over Java gateway, Zabbix server or proxy will connect to
the Java gateway and request the value, which Java gateway in turn retrieves and passes
back to the server or proxy. As such, Java gateway does not cache any values.

Zabbix server or proxy has a specific type of processes that connect to Java gateway,
controlled by the option "StartJavaPollers". Internally, Java gateway starts multiple
threads, controlled by the START_POLLERS option. On the server side, if a connection takes
more than Timeout seconds, it will be terminated, but Java gateway might still be busy
retrieving value from the JMX counter.

Zabbix server or proxy will try to pool requests to a single JMX target together as much
as possible (affected by item intervals) and send them to the Java Gateway in a single
connection for better performance.

It is suggested to have "StartJavaPollers" less than or equal to START_POLLERS, otherwise
there might be situations when no threads are available in the Java gateway to service
incoming requests.
