Hi Otto,
The basic change to use “0.0.0.0” as the default binding, and put the square
brackets in the template text instead of the parameter value, is now available
in
https://github.com/mattf-horton/incubator-metron branch METRON-905 commit
e879719a0c3fb
I’m having some trouble with my test env, so if you wanted to give it a try,
that would be great.
If the “0.0.0.0” doesn’t work, then we should use
"_local_", "_site_"
that being the ES special values that mean aprx the same.
I’m going to have to do trial-and-error to determine the exact behavior of
multi-item lists, and then write the python code to strip redundant square
brackets if included in the parameter value.
Thanks,
--Matt

I have this issue ( along with the wrong interface name ) and can test when
you have it.
An eta would help?

Are you working on this one? The JIRA doesn't look like it's currently
