I am getting the below error when adding interface bandwidth monitoring for all switches.
/var/lib/mrtg/172.16.23.2_22.rrd does not exist.
I executed the below 2 commands and getting the output as "ERROR: Line 26 (3000 Hanover St) in CFG file (/etc/mrtg/conf.d/<IP>.cfg) does not make sense" (attached the screenshot)
ls -l /var/lib/mrtg
LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg
Please help

Can you send over the system profile? It will contain that file and we can take a look at it for any errors. Thanks, Benjamin

Please edit the config file /etc/mrtg/conf.d/X.X.X.X.cfg and change this:
Code: Select all
3000 Hanover St
Palo Alto, CA 94304
To this:
Code: Select all
# 3000 Hanover St
# Palo Alto, CA 94304
Then run this again:
Code: Select all
LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg
Additionally, include the output of these commands:
Code: Select all
ls -ld /var/lib/mrtg
ls -l /var/lib/mrtg
cat /etc/cron.d/mrtg

I have edited the config file, now all interface bandwidth monitors are showing normal status.
Output of the below commands are attached here.
ls -ld /var/lib/mrtg
ls -l /var/lib/mrtg
cat /etc/cron.d/mrtg

Please run these commands to fix the permissions on them:
Code: Select all
chown -R apache.nagios /var/lib/mrtg
chmod -R 664 /var/lib/mrtg
That should do it, check it in 15 and see if the bandwidth now shows.

chmod -R 664 /var/lib/mrtg
