I wanted to let you guys know that I've released Staplr version 0.5. Staplr is a light-weight front end for rrdtool. It supports a number of plug-in monitors out of the box including Apache, memcached, MySQL and PostgreSQL. It is written in cli PHP and has a minor web PHP script to send the configuration data to the web client.
Since this is the memcached list, I'll let you know what it graphs for our favorite distributed memory object caching system: Per Daemon: - Data Usage - Connections - Data Transfer - Effectiveness (% of hits for get requests) - Evictions - Items Aggregate Graphs: There is a flexible aggregate graph system which will let you graph all daemons together or in groups, while attempting to make it easy for someone who is not a RRDTool guru. I've attached a graph showing aggregate data storage. UI wise it's good right now for small to medium sized memcached installations, large ones like Facebook would need better navigation to accommodate the nodes. This is the first public release and feedback is welcome. http://area51.myyearbook.com/staplr Regards, Gavin M. Roy CTO myYearbook.com
