Re: [Ganglia-general] install and configure ganglia

[Bernard Li]

Hi Jason: 

Disclaimer, my knowledge of SELinux is very limited, but AFAIK one just
need to set up SELinux to permissive mode and then record the behvaiour
and come up with some rules.  But perhaps this is easily said than done
:-)

Cheers,

Bernard

Yup, it looks like you have SELinux enabled.  Check the contents of the
/etc/sysconfig/selinux config file to see what level it is set to, i.e.
SELINUX should be set to one of: enforcing, permissive or disabled.  It
is most likely set to enforcing.

You have two options, either completely disable SELinux or set httpd
and/or rrdtool policies that allow the ganglia php scripts to access the
required rrd lib directory and anything else that it might need to.

Others on this list have run into this problem in the past.  Has anyone
figured out what SELinux policies are required for ganglia to function?

Re: [Ganglia-general] install and configure ganglia

[Ramon Bastiaans]

This means that rrdtool is actually not working, if you read the error 
printed by rrdtool. Also it seems it is still using /usr/bin/rrdtool 
instead of you alternate path in usr/local. Check your config again.


rrdtool complains about not having permission to load it's library..
Maybe a wild idea is to check the permissions on that file it prints?? 
(the error message already suggests this!)


Also the undefined function means that you do not have GD and/or the 
php-gd module installed.

Toney,

Have you verified that rrdtool itself works?  It may not be a problem
with ganglia you're looking at but a problem with rrdtool itself.

I'm not sure what might show up in the apache logs, but that may be a
good place to look as well.

You should be able to find your rrd databases for ganglia on the node
running gmetad (which may be all the nodes).  My installation puts them
in /var/lib/ganglia/rrds, but I'm not sure if that's the default
location.

Assuming they are there...

bash$ cd /var/lib/ganglia/rrds/__SummaryInfo__/
bash$ rrdtool graph /tmp/foo.png --end now --start end-12s \
 > --width 400 DEF:myline=cpu_nice.rrd:sum:AVERAGE \
 > LINE1:myline#FF:"foo\n"
bash$ file /tmp/foo.png
/tmp/foo.png: GIF image data, version 87a, 480 x 155
bash$ xv /tmp/foo.png #or some other way of viewing it

If foo.png is a real graph, then you have verified that rrdtool is
working correctly.  If you cannot get rrdtool to create a graph for you,
you should investigate why it is not working correctly before continuing
to troubleshoot ganglia.

Hi Ben,

I have tried as per your advise and rrdtool is working properly. I checked
the apache log also and i found this error

[client 127.0.0.1] PHP Fatal error:  Call to undefined function:
imagecreate() in /var/www/html/ganglia/pie.php on line 121, referer:
http://localhost/ganglia/
/usr/bin/rrdtool: error while loading shared libraries: librrd.so.2: failed
to map segment from shared object: Permission denied

pls guide me to resolve this problem

you are so close.  RRDTOOL is not the path to the directory but rather
the path to the binary.

define("RRDTOOL", "/usr/local/rrdtool-1.2.3/bin/rrdtool");

should work for you.

good luck

Hi Toney,

I would recommend starting here:
http://ganglia.info/docs/ganglia.html#installation

You will need to have apache installed on your head node, where you want
to view the stats through the web-based interface.

You also need to have some other packages installed, such as rrdtool.  I
believe the installation process will stall at certain parts if the
required packages are not there.  It will prompt you to install what you
need.

Good luck, and please mail back if you have more specific questions,

-ben
