Samples of JSON config

Introduction

Some sample JSON, to help you monitor quickly various metrics in :

• Sun/Oracle Hotspot heap, memory-pools, threads
• Apache Tomcat and JBoss App servers AJP/HTTP Pools and DataSources.

Graphite Samples

• In the following samples, JVM under monitoring is on an hypothetical machine named mysys.mydomain, where JMX is listening port on 8004.
• A Graphite server is installed on mygraphite.mydomain where its carbon-cache collect metrics on port 2003
