RHQ (formerly Jopr) I finally got a Raspberry Pi too.
After the hurdles of initial installation, got it hooked up to my LAN and of course I had to install an RHQ agent on it. And it turned out that this was dead simple, as the Pi already has Java 1.7 installed (in the Raspbian Wheezy distro that I am using). Thus it was only a matter of laying down the rhq-agent, and starting it the usual way. Now there was one caveat: the agent did not find any file systems or network interfaces etc. This is due to the fact that there is no native library for Sigar on arm v6 cpus supplied with the agent. I cloned Sigar from its git repository, changed into the 1.6 branch and built that library myself. Now after dropping libsigar-arm-linux.so into the agent's lib/ directory, the native library is available and on agent restart all the native stuff could be found. (Platform details in RHQ) If you don't want to compile that library yourself, you can take my version from Update Summary of installed plugins:[RHQAgent, Platforms, JMX]
Usemon - Usage monitoring of your Java client or server applications during runtime. Usemon is a monitoring system for usage trends, response time and dependency analysis of plain Java applications or big multi-clustered Java Enterprise applications running in production.
The proof of Usemon's stability and usefulness is confirmed by the fact that one of the worlds largest telecom operators is running Usemon in a clustered WebSphere environment with over 90 enterprise applications. The Usemon system consists of three separate components: Usemon AgentThe agent performs byte code manipulation of interesting classes, injecting statistics gathering code in all public methods of classes like EJBs, MDBs, SQL statements, Queue senders or configured POJOs for that matter. Data is collected in intervals of 60 seconds and transmitted to the collector for storage into a SQL database.
