A Year of Monitoring with Java-monitor
We will examine strange garbage collector behavior, talk about file descriptors in GlassFish, look at what memory leaks look like and how to tune memory pools in JVM’s. This presentation is most interesting to developers who got bullied into being the local Java system administrator too. You will learn what to monitor and look at in order to be able to assess the health of our JVM in production. I

I used the SNMP aspects of the JVM. I never really got into SNMP before and since Tiger directly supports it, the time had come. The aim was to add our JVM to an existing monitoring system, jffnms.
