We're having a problem where the RRD files are not generating for newly created network checks using the wizard. I vaguely remember something like this happening in the past after an upgrade of the XI environment. I believe the outcome was to create a new instance of the MRTG component on the server and point over to it. But I honestly have no idea what steps were taken by the technician working on it.

Just a few clarifying questions to start with...

- Which wizard is used ( I assume 'Network/Switch')?
- Are these are new checks being applied to 'new' network devices or you are re-running the wizard against an existing host?
- Are these new checks failing? In the nagios.log do you see errors such as "...rrd does not exist"? (/usr/local/nagios/var)

*If you want to add additional services on an existing host, please, follow the steps, outlined in this document https://assets.nagios.com/downloads/nag ... Router.pdf

Apologies for such a late response to this. The last couple weeks have been a little chaotic. In answer to your questions:

- You are correct, Network / Switch wizard.
- New checks to new network devices
- Confirmed errors of rrd does not exist.

Do you see any errors when you run the following command?
Note: No output is good.

Wow. Sorry I'm getting back to this so late. It's been a rough month. Here is the output:

What MRTG version are you running? env LANG=C /usr/bin/mrtg - I think the ability to use wildcards in config names is a relatively recent addition to MRTG. For reference, I am on mrtg-2.17.4

Looks like we're using mrtg-2.16.2
