How can we exclude specific alerts from participating in alert grouping or correlation mechanisms?

[Deepak Jaisingh]

We have certain alerts that should remain standalone and not be considered in any type of correlation, including:

1. Rule-Based Correlation
2. Tag-Based Correlation
3. CMDB-Based Correlation
4. Automated Correlation
5. Manual Correlation

Is there a recommended approach or configuration to ensure these alerts are completely bypassed from all correlation types?

Hi @Deepak Jaisingh 

Create a custom Alert Correlation rule .

I am trying to understand how this is going to help, can you tell me exactly how we need to achieve this
