Another graphics problem

Hi,

my graphs are not displaying. I already checked some other posts, but could not find a solution for my problem.

First of all The directory /var/lib/netmrg/rrd only contains the file zero.rrd. Does this mean, the gatherer is not working? Do I have to enable some modules to make the files appear in this directory?

The debug output of get_graph.php is
/usr/bin/rrdtool graph - -s -108000 -e -360 --title="Template Linux Box - System (UCD - CPU Percent User) (#1)" --imgformat PNG -g -w 575 -h 100 DEFdata1=/var/lib/netmrg/rrd/mon_1.rrdmon_1AVERAGE AREAdata1#151590

This also seems to work without problems.


What could be the cause for the graphs to be missing?

It sounds like the gatherer isn't running. Did you install from source or from the RPM? If from the RPM, you need to start the service to have it run (/sbin/service netmrg start); otherwise you need to setup an appropriate crontab entry.

The gatherer is registered as a cronjob. I have also executed it manually, several times and as the above output shows, it exits without errors.

What could be the problem?

Does the user the netmrg-gatherer is running as have permission to write to the rrd directory?
