Hello,

We are monitoring 16 servers using both the Zabbix agent and JMX. Periodically, our JMX connections to all servers fail and all the JMX indicators turn red in Zabbix (Configuration->Hosts->followed by Items for any given host). Our only recourse is to restart the Java Gateway.

We have turned on debugging for the Java Gateway. Unfortunately, it seems that when the log reaches 5Mb in size it automatically rolls over a maximum of three times. Because of the volume of data being logged, by the time I am aware that our JMX connections are down, the relevant log entries have been lost.

Is there anyway to increase the size of the log and the number of roll overs?

I am wondering if the number of Java pollers needs to be increased but can find no rules of thumb regarding this. We were using the default value of 5 but have increased it to 10. However, this doesn't seem to have resolved the problem.

Our Zabbix server and Java Gateway run on the same VM which runs Red Hat Enterprise 6.x.

Any assistance would be appreciated.

Trevor
