# Alert rules
|
|
|
|
An alert rule is a set of evaluation criteria for when an alert rule should fire. An alert rule consists of one or more queries and expressions, a condition, and the duration over which the condition needs to be met to start firing.
|
|
|
|
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.
