I have been trying to deal with some syslog files to store them in a DB but the format has just been too variable so I had another idea how to deal with them

My lines look like the following

The first three parts are pretty standard i.e. datetime( though with no year ) sysloghost, progname then the very variable message.

What I would like to do is convert this to a csv line as follows where its broken into at least four parts but if the string user=gonenow appears then add gonenow ( or whatever the users name was ) as an extra field, same for ip=

I dont mind either way if I end up with empty fields or no fields at the end i.e. ,, or it just ends after the end quote of the message, but I have been banging my head trying to figure this for a few days
