Hi,
any idea why the rrd files are created with world writable permissions?
For example:
-rw-rw-rw-1 nobody root11948 Sep 17 09:18
/var/lib/ganglia/rrds/unspecified/avicenna/cpu_nice.rrd
Ist that a ganglia issue or it depends more on the rrdtool?

Forgot to write back to the list about this...turns out that I just needed
to upgrade my version of PHP. You need version 4.1.

Hi folks,
I don't know if I'm just trying to push Ganglia to more than it can handle
or if I'm doing something wrong, but no matter how I design my Ganglia
structure, gmetad seems to always crush the machine where it runs. Here's
an overview of my environment:
Ganglia 2.5.4
All hosts involved
steve-
the single biggest problem with scaling gmetad is disk i/o problems. what
type of filesystem are you writing the gmetad RRDs to? most people have
had very good luck using a Ram-based filesystem and then periodically
syncing the data to disk.
for example in linux,
% mount -t tmpfs
I'm writing the RRDs to a local SCSI drive with an ext3 filesystem. I'll
investigate the RAM disk option. Thanks!

Hi Steve,
Most likely, your problems are caused by disk I/O activity because
gmetad it trying to update tens of thousands of rrd files every 15
seconds. I have switched to using tmpfs and have no problems monitoring
a little over 1,000 nodes with a single gmetad collector node. The
computer
Thanks Jason...I think I'm going to go back to my single gmetad design and
try that again with the tmpfs. I can throw as much memory as I want on that
box. I'll report back tomorrow on how well it goes with 3000 nodes :-)
