Switch monitoring wizard no bandwidth data for ports

[ctmoney]

I have a new install, and when I run the switch monitoring wizard to monitor a switch the status for the link on the switch is fine but I get the following error for bandwidth usage:

/var/lib/mrtg/172.10.10.207_1.rrd does not exist.

I have read in several places this error will occur if adding ports to an existing switch, but I get this error when adding the switch for the first time.

Installed Version: 2012R2.8b
Installed from VM Image
64 bit

We released 2012R2.8c as a fix for the Switch and Router Wizard which was released prematurely. An update should help with this.

I applied the update 2012R2.8c, cleared MRTG config, deleted switches, re-ran switch wizard and I receive the following error and the switch wizard does not complete.

Configuration submitted for processing...
Waiting for configuration verification....
Backend login to the Core Config Manager failed.

I verified that I can still login to the core config manager with the default password and this works fine. I cannot add any other services or devices to monitor either. I receive the same error.

I re-installed from scratch on a VM in my dev environment and the add device wizards work with the original install of 2012R2.8b, but once I upgrade to 2012R2.8c the wizard fails.

Please run:

Code: Select all

cd /usr/local/nagiosxi/scripts
chown nagios:nagios nagiosql*

If it still does not function properly run the following and attach the out file here, thanks!:

Code: Select all

 cd /usr/local/nagiosxi/scripts
 ./reconfigure_nagios.sh &> reconfig.txt

Great, this fixed the backend login failure but the bandwidth monitoring is still not working. Same error as before.

/var/lib/mrtg/172.10.10.207_1.rrd does not exist.

OK, what permissions do you have on these locations: (please respond with the output from all commands)

Code: Select all

ls -lvad /etc/mrtg/
ls -lva /etc/mrtg/
ls -lvad /var/lib/mrtg/
ls -lva /var/lib/mrtg/

[ctmoney]

Here you go.

[root@localhost scripts]# ls -lvad /etc/mrtg/
drwxr-xr-x 2 root root 4096 Jan 17 14:09 /etc/mrtg/

Well, those all look like the correct permissions, if you run the switch and router wizard, does the the filetime update on the mrtg.cfg file?

[ctmoney]

Yes, the mrtg.cfg files updates. Below is the start of the config for the file. The port status monitors just fine, it's the bandwidth that is reporting unknown with the "/var/lib/mrtg/172.10.10.208_10.rrd does not exist." error

It looks like you are missing a chunk of data from the top of your mrtg.cfg, the file should start with these directives

Code: Select all
