Configuring Identification Rules

You have the following operation permissions: Set Identification Rules.

A rule is valid only to the alarms reported after the rule is enabled.
Before an identification rule takes effect, Validity is set to Valid and Maintenance Status is set to NORMAL by default. The NORMAL state corresponds to the Normal state.
A maximum of 1000 identification rules can be created.
By default, the rules are sorted by the enabled and disabled states, and the rules in the same state are sorted by update time in descending order.

Choose Device Management > Alarms Management > Alarm Settings from the main menu.
In the navigation pane, choose Identification Rules.
On the Identification Rules page, click Create.
In the Basic Information area, set the rule name, description, and whether to enable the rule.
In the Conditions area, set the alarm severities, alarms, and alarm sources for the rule to take effect. Set advanced conditions to filter the alarms for the rule to take effect based on alarm parameters.

All alarm sources is available only when the user can manage all resources.
In the Time Filter area, set the time and period for the rule to take effect as required.
In the Action area, select the status of alarms you want to identify.
