Works fine after downloading MIBs

After some problems with errors because of the missing MIBs the plugin works fine. Thank you.
Only 4 “stars” rating because of the problems with the MIBs. I don’t know if i solved it without the hint from csdragon. Thank you!
Maybe you could add a check for the needed MIBs with a clear error message, if they are missing.

If somebody has got the same problem:
I’m using Debian. First you need to add a “non-free” repository to your “sources.list”.
After that you can install die “mibs-downloader” with “apt-get install snmp-mib-downloader”. While installing it automatically downloads all official IETF Mibs.
