Staplr is a light-weight front end for rrdtool. It supports a number of plug-in monitors out of the box including Apache, memcached, pgBouncer 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 PostgreSQL list, I'll let you know what it graphs for a standard PostgreSQL install: Per Database: - Backends - Locks - Size on Disk - StatIO - Transactions per Second - Write Activity Aggregate Graphs: There is a flexible aggregate graph system which will let you graph all databases together or in groups, while attempting to make it easy for someone who is not a RRDTool guru. This is the first public release and feedback is welcome. http://area51.myyearbook.com/staplr Regards, Gavin M. Roy CTO myYearbook.com
