Syslog viewers are broken. I haven't yet found any with the analytical ability that I'm after. Therefore I thought that I should build one.
The question is, if this was a web service, would you consider using it? Would you send your logs to a 3rd party (using TLS)?
Exceptional (http://www.exceptional.io/) does something similar but with Application Logs. Check them out. It is a pretty cool idea. I think you should build a proof of concept.
I would certainly use it.
