Hi All, Anyone using Ganglia to monitor their servers might be interested to know that Ganglia 3.3 now includes support for mod-sflow, providing a great way to monitor the health of an Apache cluster - not just HTTP performance, but also the CPU, memory, disk and network I/O. If you are using Tomcat for the application tier, the SFlowValve exports HTTP and JVM metrics. If you are using a Memcached cluster for caching, there is an sFlow agent available. For more information, see: http://blog.sflow.com/2012/02/ganglia-33-released.html There is also a solution for Graphite: http://blog.sflow.com/2012/01/graphite.html The following case study from Tagged.com, a large social networking site, describes some of the operational benefits of using sFlow for monitoring: http://blog.tagged.com/2011/11/host-based-sflow-the-drop-in-cloud-friendly-monitoring-standard/ Peter --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
