OVERVIEW

12       This Nagios plugin for Tang enables Nagios to monitor a Tang server for
13       its basic functionality as well as performance metrics. The  plugin  is
14       executed simply by providing the base URL to the Tang service.

17
18       1.  Downloading the advertisement.

28       If  any  of these tests fail, an error will be generated. Upon success,
29       the plugin will output the following performance metrics:

31       ·   adv : Time it took to fetch the advertisement (in μs).
