I'm having > trouble with scalaing ganglia to work on large clusters. Have you considered turning off disk read-ahead on the partition that includes the .rrd files? That should help somewhat. There's a good paper that discusses the performance of MRTG (a heavy user of rrdtool), and how to make it scale nicely: http://www.usenix.org/event/lisa07/tech/plonka.html Note that the patch to rrdtool mentioned in in the paper is includined in rrdtool 1.2.24 and later. -- Jesse Becker GPG Fingerprint -- BD00 7AA4 4483 AFCC 82D0 2720 0083 0931 9A2B 06A2 ------------------------------------------------------------------------ - This SF.net email is sponsored by: Microsoft Defy all challenges.
