Apache ActiveMQ Monitoring
Overview
Apache ActiveMQ is the most popular and powerful open-source messaging server. ActiveMQ apart from being powerful and open source, it is the most light weight messaging server compared to other messaging servers like JBossMQ and Tibco EMS.
In this document, we have described about Cavisson monitoring support to Active ApacheMQ service provider.
