A bit ad-hoc formatting for the log, but that's mostly because cluster.log
only has message field and I don't think having a dedicated application_name
column is worth it. That could also be added by custom scripts if it's really
wanted for a given deployment.
This only changes the script-layer API, but keeps the std::string host
in the C++ layer's ServerOptions. Mostly because the ixwebsocket library
takes host as std::string. Also, maybe at some point we'd want to
support something scheme-based like unix:///var/run/zeek.sock and placing
that in a string could not be totally wrong.
Add tests for IPV6, too.
Limit the number WebSocket events queued from external clients to
dispatcher instances to produce back pressure to the clients if
Zeek's IO loop is overloaded.
