Notes:
- Generally, it is better to use the following option (and particulary in case the hostnames are different from the host address): -h
$HOSTNAME$
That will permit to the script to generate a correct link to the pnp4nagios graphs. - For options --exclude, --include, --exclude-traffic, --include-traffic, --track-property, --exclude-property and --include-property:
- These options can be used multiple times, the lists of interfaces/properties will be concatenated.
- The separator can be changed using the --ifs option.
- All these default values can be easily changed to fit your environment, by changing the definition of the '%ghOptions' hash in the script itself.
- Print plugin usage
Lots of changes has been done on the plugin. The plugin usage has consequently changed. Look at the help for a complete explanation of each option:
