This behavior has been introduced by commit:548a3b2c93aed79e39a34ee9dd4c68f43a27f363. Idea was not to create flows for icmp error messages.

I can imagine it would make sense to create a flow for echo/echoreply. But other than echo/echoreply what icmp should lead to a flow?

Good morning,

I initially reported this issue in the SELKS Google group. In this case, I'm attempting to use the suricata logs and elk stack to analyze icmp v4/v6 traffic (among other things). Ideally, I'd like to be able to see all icmp types. Still, flows for echo request and reply alone would be beneficial. As of right now the only workaround is to generate simple alerts based off icmp type. I'd like to avoid that if possible. Would there be a way to turn off / on the creation of icmp flows?
