Python script that uses the mminfo binary on the nagios server to check the status of the last
day savesets on the networker server. If the saveset is older than 1 day the status ist critical.
If no savesets for the client are reported, the check will be fine.

Prerequisites:
The networker client has to be installed and configured.
Try at first "mminfo" for tests. http://www.ipnom.com/Legato-NetWorker-Commands/mminfo.html
In order to run the python script, install the pynagios libararies http://pypi.python.org/pypi/pynagios.

I.e. on Ubuntu:
1. apt-get install pip
2. pip install --proxy proxy:port --upgrade pip
3. pip install --proxy proxy:port --upgrade virtualenv
4. pip install --proxy proxy:port pynagios


Usage:
./nwcheck.py -H hostname.domain.name --server backupserver --timeout 10
./nwcheck.py -H hostname --server backupserver --timeout 10

-H = Hostname in fqn or normal form (no ip address)
--server = Name or IP of the networker server
--timeout = timeout value for killing the mminfo process
