rex construction help

New Member

Hi there I´m creating a REX to extract data from a raw field like this
2013-07-08T09:33:59.899088-05:00 10.27.253.125 553623: 2015101: Jul 8 10:00:01.474: %MAC_MOVE-SW1-4-NOTIF: Host 6c88.1468.b350 in vlan 592 is flapping between port Te1/7/2 and port Te1/7/1

with this expression
... | rex field=_raw "Host (?.) vlan (?.[0-9])" | chart c(hot) by hot

But in the "hot" extracted field appears "6c88.1468.b350 in"
I want to get rid of the " in" part so I can get 6c88.1468.b350

How can I make that?

Not sure if that regex string got formatted correctly, however, here is something that might work for you:

| rex field=_raw "Host (?<hot>\S+) in vlan (?<vlan>.[0-9]+)" | chart c(hot) by hot
