The PMM collects statistics from a Nagios server

This PMM uses the JSON API build into Nagios (since Nagios 4.0.7) to retrieve performance data.

The statistics are taken from the 'perf_data' field. When more than one value is available, a @ sign will be added with an index, for example: CPU=12;80;90 will appear as CPU, CPU@2 and CPU@3. The meaning of the statistics depend on the Nagios plugin used.
