> Alarm inhibition is used to configure the inhibition relationship between alarms. When an alarm occurs, other alarms can be suppressed. It can be understood as "important" alarms suppressing "
|
|
> unimportant" alarms. For example, the alarm generated by a server crash suppresses the alarms generated by other services on this server.
|
|
|
|
## Prerequisites
|
|
|
|
- Correctly configure the alarm grouping rule
|
|
|
|
## Inhibit rule configuration
|
|
|
|
- Inhibit Rule Name: The name that uniquely identifies the suppression rule
|
|
|
|
- Source Labels: When the alarm contains these tags, the target alarm will be suppressed. Multiple tags can be added.
|
|
|
|
> Identify the tag of the "important" alarm. The alarm tag needs to contain all source tags to suppress the alarm marked by the target tag.
|
|
|
|
- Target Labels: Alarms matching these tags will be suppressed.
|
|
|
|
> Identify the label of "unimportant" alarms. Alarm labels need to contain all target labels to be suppressed.
|
|
|
|
- Equal Labels: Labels for determining alarm correlation. Supports up to 10 labels.
|
|
- Enabled: Enable or disable this inhibit rule
|
|
|
|
## Example
|
|
|
|
Scenario: Use HertzBeat to monitor two Centos servers 192.168.1.1, 192.168.1.2, and Redis services Redis-1 and Redis-2 deployed on the two servers.
|
|
And configure the following threshold rules:
|
|
|
|
- Monitor Centos Linux / Monitor availability. Bind label `server-status:down`
|
|
- Monitor Redis database / Monitor availability. Bind label `redis-status:down`
|
|
|
|
If you need to achieve that when the Centos downtime alarm is generated, the Redis alarm will no longer be generated, you can configure the following alarm suppression rules:
|
|
|
|
- Source label: `server-status:down`
|
|
- Target label: `redis-status:down`
|
|
- Equal label: `instancehost`
|
|
|
|
When the Centos 192.168.1.1 downtime alarm is generated, the Redis-1 unavailable alarm will no longer be generated. And at the same time, when Centos 192.168.1.2 is running normally and Redis-2 is
|
|
unavailable, the alarm notifying Redis-2 unavailable will be generated normally.
