Hello Raphael,
Thank you for the reply. I cannot add the rule in full here because of some client information in the rule. but most of the part of the rule is from out of the box sentinel rule called Mass Secret Retrieval From Azure Key Vault. For entity mapping in sentinel we have used following fields
- OperationNameList - This will have list of operations that triggered the alert.
- CallerObjectId - This is the account that performed the action
- CallerIPMax – This is most recent IP from which this operation was performed.
We have done following settings :
Under incident settings we have done following settings:
Even though all the entity are matching this rule is creating incident every hour and not grouping then into incident.

hello
you are using to group when it matches account, id , process. As the ip and the process will always be different, then there will always be a non-grouped incident because it does not match the selected fields.
Select last option and mark account
About the alerts it is generating too many and because you are evaluating every hour with 1 day data polling time, try to run every 1 hour with 1 hour polling time.
if you liked it mark the answer with a like.

Hello,
I have checked the ip and process they were same in each incident it generated every hour but was still not grouping. Thank you for the information. I will try reducing polling time as well.
