# About alert rules
|
||
|
|
|
||
|
|
An alerting rule is a set of evaluation criteria that determines whether an alert instance will fire. The rule consists of one or more queries and expressions, a condition, the frequency of evaluation, and optionally, the duration over which the condition is met.
|
||
|
|
|
||
|
|
While queries and expressions select the data set to evaluate, a condition sets the threshold that an alert must meet or exceed to create an alert.
|
||
|
|
|
||
|
|
An interval specifies how frequently an alerting rule is evaluated. Duration, when configured, indicates how long a condition must be met. The alert rules can also define alerting behavior in the absence of data.
