An Open-Source tool for Glassfish Performance Monitoring [closed]

Question

It seems the Glassfish Performance Monitor is commercial. When I wanted to download it from Oracle website it shown me a restriction.

Would you please suggest me an open-source monitoring tool for glassfish V3?

Answer 1

I highly recommend Visual VM with the Glassfish plugin. Having purchased the GF Performance Monitor (which isn't open source or updated) I can say Visual VM does a better job. BTW, the GF plugin was written by the same folks who wrote the GF Performance Monitor.

JavaMelody is another open-source monitoring tool for webapps.
