how to configure MRTG for multiple nodes

[barry1946]

at the blink of an eye.I mean i change it to nagios.nagios then I do ls -l and it is ... root.root
so if we could solve this issue of re-return , maybe we can solve the problem!

What command are you using? Are you typing "nagios.nagios" or "nagios:nagios"?

[barry1946]

nagios.nagios

hmmm. mrtg is usually processed on a cron. I wonder if the cron is not setting the proper permissions. What is the output of:

Code: Select all

cat /etc/cron.d/mrtg

[barry1946]

*/5 * * * * root /usr/bin/mrtg /etc/mrtg/mrtg.cfg --lock-file /var/lock/mrtg/mrtg_l --confcache-file /var/lib/mrtg/mrtg.ok

actually this is the original line that were automatically created after installing mrtg and I just uncommented it
there are plenty of suggestion out in the wild and I do not know which one to take.
I appreciate your suggestion for the cron.d/mrtg correct entry in this regard

I think the .log file becomes root:root because of the crond,
because the cron I set to 1 minute check after 1 minute the .log file in /var/www/mrtg/ becomes -rw-r--r--
also cron says: LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg --lock-file /var/lock/mrtg/mrtg_l --confcache-file /var/lib/mrtg/mrtg.ok
content-type: type: text/plain;charset=UTF-8
I really need to solve this issue, I need help

[barry1946]

I did LANG=en_US
export LANG
but still unable to open logfile for mrtftraf

What are the permission on check_mrtgtraf?

EDIT: And your umask settings:

Code: Select all

umask

[barry1946]

it is 0022

What about check_mrtgtraf?

Code: Select all

ls -la /usr/local/nagios/libexec/check_mrtgtraf
