$ check_jitter --help
A Nagios compatible plugin that measures network jitter.
Thresholds are defined using Nagios range syntax. Examples:
+------------------+-------------------------------------------------+
| Range definition | Generate an alert if x... |
+------------------+-------------------------------------------------+
| 10 | < 0 or > 10, (outside the range of {0 .. 10}) |
+------------------+-------------------------------------------------+
| 10: | < 10, (outside {10 .. ∞}) |
+------------------+-------------------------------------------------+
| ~:10 | > 10, (outside the range of {-∞ .. 10}) |
+------------------+-------------------------------------------------+
| 10:20 | < 10 or > 20, (outside the range of {10 .. 20}) |
+------------------+-------------------------------------------------+
| @10:20 | ≥ 10 and ≤ 20, (inside the range of {10 .. 20}) |
