check_mrtgtraf: Unable to open MRTG log file

This is what i get when i run the command you mentioned.

[root@NAGIOS01 /]# /usr/lib64/nagios/plugins/check_mrtgtraf -F /var/www/html/mymrtg/10.0.1.1_2.log -a AVG -w 1000000,1000000 -c 5000000,5000000 -e 10
Traffic OK - Avg. In = 141.3 KB/s, Avg. Out = 11.1 KB/s|in=141.305664KB/s;1000000.000000;5000000.000000;0.000000 out=11.091797KB/s;1000000.000000;5000000.000000;0.000000

 

Ok, so from your reply we can assume the plugin works when run as root.
afaik see all files have the correct permissions to run this thing

maybe try:

Code:

sudo -u nagios /usr/lib64/nagios/plugins/check_mrtgtraf -F /var/www/html/mymrtg/10.0.1.1_2.log -a AVG -w 1000000,1000000 -c 5000000,5000000 -e 10

If that gives correct output, the error you told us about in your first post is either from an old log line or another object, because if the above is all true it SHOULD work.
If not, you forgot something to tell us

 

This is what I get when I run the command above.

[root@NAGIOS01 /]# sudo -u nagios /usr/lib64/nagios/plugins/check_mrtgtraf -F /var/www/html/mymrtg/10.0.1.1_2.log -a AVG -w 1000000,1000000 -c 5000000,5000000 -e 10
Traffic OK - Avg. In = 31.6 KB/s, Avg. Out = 12.3 KB/s|in=31.614258KB/s;1000000.000000;5000000.000000;0.000000 out=12.309570KB/s;1000000.000000;5000000.000000;0.000000


I have no idea why it is still telling me check_mrtgtraf: Unable to open MRTG log file

 

I also see this in the mrtg.log

Started mrtg with config '/etc/httpd/conf/mrtg.cfg'
2012-11-27 10:55:02 -- ERROR: I Quit! Another copy of mrtg seems to be running. Check /etc/httpd/conf/mrtg.pid

any ideas?
thanks.
