Hello If this were logged it would be in the LifeCycle Controller log. I tested and it does not log individual changes to alerts, but if you enable or disable  all alerts it will log that activity in the LCC log. It does not appear that snmp alerts are configurable for the LCC log. Thanks
Is there a way to alert on changes to the idrac snmp alerts, such as disabling an alert? Does a log show this activity? Thanks!
Alert and or log changes to idrac snmp alerts
