Rules Concepts

A rule is an alarm check mechanism that allows for complex or special purpose logic in determining the status of a monitored host or node.

There are two types of rules:

• Simple rules are based on the rCompare rule, in which monitored properties are compared to the rule. If the rule condition becomes true, an alarm is generated. For example, a simple rule can be the percentage of disk space used. If the percentage of disk space used is greater than or equal to the percentage specified in the rule, then an alarm is generated.

• Complex rules are based on multiple conditions. For example, one complex rule states that an alert alarm is generated when the following conditions are met:

  • The disk is over 75% busy

  • The average queue length is over 10

  • The wait queue is increasing
