Nagios Support Forum

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?

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 the the following, and report any errors Also, can you show the output of

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:

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

Let's run the following: Then try this again

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)?

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

-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!
