Situation descriptions
Each situation description provides information about the situation that you can use to monitor the condition of systems in your network.
The situation descriptions provide the following information:
- Description
- Information about the conditions that the situation tests.
- Formula
- Syntax that contains one or more logical expressions that describe the conditions for the situation to monitor.
- Distribution
- Whether the situation is automatically distributed to instances of the agent or is available for manual distribution.
- Run at startup
- Whether the situation starts monitoring when the agent starts.
- Sampling interval
- Number of seconds that elapse between one sample of data that the monitoring agent collects for the server and the next sample.
- Situation persistence
- Whether the conditions specified in the situation evaluate to "true" for the defined number of occurrences in a row before the situation is raised. The default of one means that no persistence-checking takes place.
- Severity
- Severity of the predefined events: Warning, Informational, or Critical.
- Clear conditions
- Controls when a true situation closes: after a period, when another situation is true, or whichever occurs first if both are selected.
