Nagios Support Forum

I've run the Network device wizard to add several network devices. However, many of the checks are failing. The failing checks all report "/var/lib/mrtg/xxxx.rrd does not exist."

It appears that the mrtg.cfg is not being updated with the new information? Suggestions?

Are you running the wizard against a "new" network device or you are re-running it against an existing host? If you want to add additional services on an existing host, please, follow the steps, outlined in this document.

It is working now.

I ran the fix permissions script and then re-added all the network hosts. Any hosts added before I ran the fix perms script still do not have RRD files being generated.

So did re-adding them fix it, or are some of the rrds still broken?

Any hosts added before I ran the fix perms script still do not have RRD files being generated.

Try removing these hosts, then follow the four steps, outlined in the "Adding Service Switch or Router" document (see my previous post). Hope this helps.
