Eventlog e-mail should indicate which server's Eventlog has the error.
I am happy to see the new Eventlog error included in the email with 8.5. It uncovered an issue for us though, since we are using 4 servers in a BizTalk group. My original alert does not indicate which of the 4 servers are throwing the error. My clunky workaround was to have 4 alerts - one for each server, but I would prefer to have the server name in the EventLog content in the e-mail.
Before I made the change, I would get one alert with 1-4 event log items and I had to search until I found the right server(s) with the errors.
This feature was introduced as part of v8.6, Event Log Data Monitoring feature.
Kindly get back to us should you have any other queries.
