Thresholds can be defined for detecting instability for a host or a service. Except in exceptional cases, they must comply with Nagios syntax as shown below.
This syntax is used to define advanced thresholds and as such, enable more precise monitoring of host behavior.
| Syntax | Will produce a warning if... | Example | ||
|---|---|---|---|---|
| 10 | 10, (outside the range {0 .. 10}) |  | ||
| 10: | < 10, (outside the range {10 .. ∞} |  | ||
| ~:10 | > 10, (outside the range {-∞ .. 10}) |  | ||
| 10:20 | < 10 or > 20, (outside the range {10 .. 20}) |  | ||
| @10:20 | ≥ 10 and ≤ 20, (within the range {10 .. 20}) |  |
