mrtg for Nagios XI - .rrd files are not being created

[aastaguy]

Hello,

I know this post has been covered several times, but when I run the "Network switch/router configuration wizard" on a switch (Cisco), the wizard does the snmp scan and returns about 10 ports that can be monitored, I set it all up and finish, and ping works, but all I see in the bandwidth service is /var/lib/mrtg/ipaddress_10.rrd does not exist. so the rrd files are not being created.

I have looked at the .cfg file and cleared out all snmp scans, I have checked the time and restarted the npcd service, I have ran the following command env LANG=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg and receive the following output:

ERROR: unable to open include file: /etc/mrtg/conf.d/*.cfg

I have looked at just about every post on this topic to see if I can solve it myself but to no avail. Any help is greatly appreciated.

Thank you.

Can you show the output of the following?

Code: Select all

ls -al /var/lib/mrtg

the thing I notice is that the ip in question that I ran the wizard on does not exist. 192.168.191.93

Lets run the following command

Code: Select all

rm -f /var/lib/mrtg/mrtg.lock

the the following, and report any errors

Code: Select all

LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg --lock-file /var/lib/mrtg/mrtg.lock --confcache-file /var/lib/mrtg/mrtg.ok --user=nagios --group=nagios

Also, can you show the output of

Code: Select all

ls -al /etc/mrtg/conf.d

[aastaguy]

Thanks for your quick reply!

The first command to remove the lock went fine and din't report anything

The 2nd command gave me the usual following output:

ERROR: unable to open include file: /etc/mrtg/conf.d/*.cfg

The 3rd command output is below, where the host (192.168.191.93.cfg) does in fact exist:

Thanks.

ERROR: unable to open include file: /etc/mrtg/conf.d/*.cfg

This is quite bizarre because you were actually able to list the directory as root

Let's run the following:

Code: Select all

chown apache.nagios -R /etc/mrtg
chmod ug+wr -R /etc/mrtg/conf.d

Then try this again

Code: Select all

LANG=C LC_ALL=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg --lock-file /var/lib/mrtg/mrtg.lock --confcache-file /var/lib/mrtg/mrtg.ok --user=nagios --group=nagios

[scottwilkerson]

Also, what version of Nagios XI are you running?

And the version of the Switch wizard from Admin -> Manage Config Wizards (latest is 2.5.2)?

[aastaguy]

I agree on the bizarre part! After I change permissions, I get the same error:

ERROR: unable to open include file: /etc/mrtg/conf.d/*.cfg

I am running 2.4.3 for the Network switch/router config wizard.

Thanks!

I would strongly suggest updating the wizard as there were a few versions causing similar errors

what do you get when you run

Code: Select all

su nagios -c 'ls -l /etc/mrtg/conf.d/*.cfg'

[aastaguy]

-rw-rw-r-- 1 apache nagios 11712 Nov 8 2018 /etc/mrtg/conf.d/172.16.191.90.cfg
-rw-rw-r-- 1 apache nagios 11717 Nov 8 2018 /etc/mrtg/conf.d/172.16.191.91.cfg
-rw-rw-r-- 1 apache nagios 15807 Feb 19 10:51 /etc/mrtg/conf.d/192.168.191.93.cfg

I will update now and see what happens. I will report back.

Thanks!
