I've log messages that looks like this
07:17:58.211 [Thread.3;] INFO Dispatcher - Message from XXX.XXX.XXX.XXX/PORT not dispatched, reason: blah blah, status=xyz
I'm trying to query then visualize the different IP address (XXX.XXX.XXX.XXX) by their count. I tried the following query in KSQL message: /[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}/
but I'm getting this error
KQLSyntaxError: Expected AND, OR, end of input, whitespace but "{" found.
message: /[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}/

What is the proper way of querying with regex?
