No, that would be a feature request to link the syslog data source IPs and sensor names. As far as clients go, though, all of that information is now consolidated under the Clients page - you can add columns including number of logs today, last heartbeat, etc. Hope that helps!
So, I've tried to add just one that is showing up incorrectly. I've waited at least 30 mins, but I'm not seeing new events come in under that sensor name. Is there no way to reset/reindex the calculated sensor name? I'd prefer to not add every source as a sensor in the LCE config.
