Overview

Alert triggers every time you change something in the node (delete or remove node or interface).  Also, there is false alert every time the node / interface has change / delete.

Environment

All NPM versions

Steps

Tables to Identify

AlertObjects when active alert is triggered and for triggered swis entity doesn't exist record here, record is added. When alert is reset record is not deleted. About deleting orphaned record takes care database maintenance
AlertActive

contains currently active alerts i.e. when alert is triggered then a new record is created for a given object, when alert is reset then record is deleted for a given object.

AlertActiveObjects

is used just for global alerts (just one alert is triggered when more objects fulfill trigger condition). It contains a list of objects which triggered the alert.

AlertHistory

here is stored every action done with active alert such as trigger, reset, acknowledge, added note, action execution.

AlertConditionState is used by the service to persist evaluated alert conditions
  1. Check Alerting.Service.V2.log and look ERRORS that has AlertObjectIDs.
  2. Open AlertHistory table, search for AlertObjectIDs from step 1 and take note the corresponding AlertObjectIDs.
  3. Open AlertObjects table, search for AlertObjectIDs from step 2 and take note the corresponding AlertIDs.
  4. Open AlertConfigurations an search for the AlertIDs from step 3.

 

Once confirmed that this is a false alert and databse is not updated, re-sync the database using configuartion wizard -- database.
