[GitHub] [cloudstack] nvazquez opened a new issue, #6613: Improvement on administrator alerts
nvazquez opened a new issue, #6613:
URL: https://github.com/apache/cloudstack/issues/6613
##### ISSUE TYPE
* Improvement Request
##### COMPONENT NAME
~~~
Alerts
~~~
##### CLOUDSTACK VERSION
~~~
4.16.1 and onwards
~~~
##### CONFIGURATION
Use the default values for the configurations:
- capacity.check.period : 300000
- alert.purge.delay : 0
- alert.purge.interval : 86400
- Define notification thresholds for cluster capacity: (for example cluster.storage.capacity.notificationthreshold : 0.75 )
##### OS / ENVIRONMENT
N/A
##### SUMMARY
The first time a cluster threshold is exceeded CloudStack notifies the administrator by sending an email and creates a record on the `alert` table. If the alert.purge.delay value is set to 0 (default value) then this record is never deleted, so the next time the threshold is exceeded the administrator does not get notified. CloudStack queries the database and searches for records on the `alert` table for the same alert type and cluster, and in case it finds an existing records it does not send the notification email.
Example:
DB:
````
mysql> select * from alert where type = 3 and cluster_id = 1 and archived = false;
