Dear RRDTool and Ganglia developers: For the last few days I have been working on integrating rrdcached with Ganglia and the preliminary results are pretty promising.
On my benchmark server running gmetad, without rrdcached the load would get way up there making the server unusable (due to high I/O wait). With rrdcached enabled, the load barely hit 2 and I/O wait is low. I will post some more data later (maybe summary of `sar` output). For Ganglia, both gmetad and apache processes need to access the rrdcached socket, so I had the socket owned by nobody chgrp it to apache (also making it group-writable). If anybody is interested in testing this on EL4, I could post my RPMs. Code modification to Ganglia is pretty trivial. I look forward to the official release of rrdcached as part of an upcoming rrdtool release! Special thanks to Florian, Kevin and Tobias for their hard work in putting this together!
