Are you using your own created log messages or relying on the ones created by Mendix? If you create your own you can of course just set the “log node name” which will allow you to filter it. Might I suggest looking at the “Logging Module” in the app store. This will put your logs in a datagrid that you can filter however you’d like
If you mean you have many of the same requests coming in, I suppose you could create some sort of Unique Identifier at the start of the microflow, which can then be used in all log messages for that particular transaction.
