RE: [Ganglia-general] Ganglia graphs not showing

[matt massie]

dr. matroid (cool name)-

the fix would be to simply tell the web frontend where to find your 
round-robin databases (since they are in a non-standard place).

all configuration options live in the "./config.php" file.  open it.. and 
edit the line

$rrds = "$gmetad_root/rrds";

to read

$rrds = "/home/m254/rrdtool";

and you should be set.

good luck!

RE: [Ganglia-general] Ganglia graphs not showing

[Dr. Matroid]

As Mr. Spock would say, "fascinating." Behold, the contents of /etc/gmetad.conf 
at the crucial end:
 
# Where gmetad stores its round-robin databases
# default: "/var/lib/ganglia/rrds"
# rrd_rootdir "/some/other/place"
rrd_rootdir "/home/m254/rrdtool"

And indeed, /home/m254/rrdtool has what it is supposed to have.
[EMAIL PROTECTED] etc]#  ls /home/m254/rrdtool/
monad cluster  __SummaryInfo__
[EMAIL PROTECTED] etc]#
 
However, as noted before,
 
/var/lib/ganglia/rrds had nothing in it. When the empty directory
 
/var/lib/ganglia/rrds was replaced with a symbolic link to the new rrd_rootdir,
the graphs returned!!
 
[EMAIL PROTECTED] ganglia]# pwd
/var/lib/ganglia
[EMAIL PROTECTED] ganglia]# ls -latrs
total 3
   1 drwxr-xr-x2 nobody   nobody   1024 Feb  2 15:35 rrds.nowitsalink
   1 drwxr-xr-x   23 root root 1024 Mar  2 17:18 ..
   0 lrwxrwxrwx1 root root   19 Apr  5 23:43 rrds -> 
/home/m254/rrdtool/
   1 drwxr-xr-x3 root root 1024 Apr  5 23:43 .
[EMAIL PROTECTED] ganglia]#

So, the configuration file is not being heeded, or else, if the 
/var/lib/ganglia/rrds directory
is present, the new location is ignored. 
 
We are using: [EMAIL PROTECTED] ganglia]# uname -r
2.4.20-6smp
[EMAIL PROTECTED] ganglia]#

And, rpm reports that the relevant packages are:
 
ganglia-monitor-core-gmetad-2.5.6-1
ganglia-monitor-core-gmond-2.5.5-1

Have I erred?

The contents of /var/lib/ganglia/rrds is empty!!
 
[EMAIL PROTECTED] rrds]# pwd
/var/lib/ganglia/rrds
[EMAIL PROTECTED] rrds]# ls -latrs

I don't know what this ought to contain either...

Can you take a look at the directory /var/lib/ganglia/rrds and let us
know the contents?  Chances are the files are based on the old ip and
you will need to modify the files to reflect the ip change.
 
Cheers,
 
Bernard

Subject: [Ganglia-general] Ganglia graphs not showing


After changing IP addresses of my cluster's internal network,
ganglia's graphs (generated by rrdtool, I believe) do not display at
all. I haven't seen a specific reference to this problem in the archive.
What to do? The ganglia cluster display is here:
http://monad.gc.cuny.edu/ganglia.
 
Thank you.
