Nagios Support Forum

Hi Kyang, I'm not sure what happened, but I changed the /var/www/html permissions and owners to nagios:nagios 777, then revert it back to root:root 755. I made a lot of tweakings between the folders /var/lib/, /var/mrtg/, /usr/local/nagios/share/perf/ , and it's working now. maybe it has something t...

Hi! I got it working!! just for history purposes, incase anyone might encounter. I'v updated the check_mrtgtraf plugin. I used the one for Centos6 here's the link: https://centos.pkgs.org/6/epel-x86_64/nagios-plugins-mrtgtraf-2.2.1-4git.el6.x86_64.rpm.html We can close this now. Thank you very much!

Hi @npolovenko I ran these commands: cd /var/lib/ and run: chmod -R 777 mrtg but this one seems invalid, I having an error: chmod apache,nagios mrtg "chmod: invalid mode: âapache,nagiosâ Try 'chmod --help' for more information." I'd try to do chown apache:nagios mrtg, restart services and ...

Hi Kyang,

I did try that, and even rebooted the server. I sent you a PM for the logs

Hi Kyang, Here you go for the last part: [root tmp]# grep check_external /usr/local/nagios/etc/nagios.cfg check_external_commands=1 [root tmp]# ll /usr/local/nagios/var/rw/ total 0 -rwxrwxrwx 1 nagios apache 0 Jul 30 2016 live.old prw-rw---- 1 nagios nagcmd 0 Dec 8 16:23 nagios.cmd srw-rw---- 1 nagi...

Hi @npolovenko, i sent you a Private message. i am wondering if I still need to setup a MRTG on the new server, Is that also a pre-requisite for this part? or is the plugin not compatible with the current version of Centos? I am using Centos 7 64bit Are there also pre-requisite besides the documenta...

Update:

I tried to convert few rrd files under /var/lib/mrtg and re-run the command
LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg -debug=cfg,base &> /tmp/mrtg.txt

check the file and this is what I found: --base: Act on Router/Target 1.2.3.4
but I still get 0/0 in/out on Bandwidth

Hi @npolovenko,

No, not sometimes, it happened only when I migrated it to the new server. Old server is working fine.

I also tried that but it's not creating a new file, I attached the error I am getting.

Hi Kyang, Thank you for the response, I'm using http only. Should the Program URL and External URL be the same? That's how it was set before on the old server so I'm assuming they would still work. Yes, some work, and some not. like for this example, so I tried to remove the acknowledgement, and it ...

Hi Kyang,

I sent you a private message, for the acknowledgement, I just noticed that it only happens on some servers, is there a way to remove the acknowledgement?
