Re: [Ganglia-developers] Testing RRDtool 1.3rc7 with Ganglia on CentOS 4.x
The tmpfs choice for us was because iostat showed 100% utilization, and strace confirmed the steady stream of mkdir's going constantly. -j - Original Message From: Bernard Li [EMAIL PROTECTED] To: ganglia-developers ganglia-developers@lists.sourceforge.net Sent: Friday, June 6, 2008 5:17:06 PM Subject: [Ganglia-developers] Testing RRDtool 1.3rc7 with Ganglia on CentOS 4.x Hi guys: I was able to build RRDtool 1.3rc7 on CentOS 4.x and use it with Ganglia 3.0.7. I noticed there weren't much difference in system resource utilization: iostat shows ~2MB/s write, top shows load is roughly 4 (this is roughly the same as system running rrdtool 1.2.23). The main difference I notice is that the frontend's graphs actually looked fine. With version 1.2.23, I have a lot of gaps in the Load summary graphs (the red, green, blue lines which represents CPUs, Nodes and Running Processes respectively), with 1.3, the graphs don't have gaps (or at least very rarely have gaps). I noticed that the time it takes to generate the graphs is slightly faster. If you are interested in testing this for yourself, I have put the necessary RPMs online here: http://therealms.org/oss/ganglia/rrdtool/ First, you need to upgrade glib2*, then install pango and ultimately rrdtool (I make no guarantees that installing these RPMs won't break your system, they do install correctly though ;-) ) If you are able to test it, please do share your thoughts. I'll continue to run more tests. Also, please let me know if you need the SRPMs for any of the packages.
