Ed: correct me if I’m wrong, but IIRC we must not put GPLv2 into an fd.io 
gerrit repo...

Thanks… Dave

Dave,

Collect plugins run in the collectd process itself, so this licensing only 
applies to the plugin code itself. Nothing specific to collectd actually links 
to VPP.

Steve Shin wrote a first version of collectd plugin in python that queries VPP 
by invoking vppctl and parsing the output (I guess we could use the python 
client API as well although licensing for python code is a bit special). It can 
extract all vpp interface stats with the proper collectd config.

Thanks

  Alec

That looks like a show-stopper to me.

Subject: [tsc] collectd

I took a note to have a look at collectd during yesterday’s vpp project call.

There appears to be a license issue. See 
https://collectd.org/wiki/index.php/Plugin_architecture - “The [plugin] license 
must be compatible to collectd's own license, the GPL 2.”

Give that all fd.io code carries an Apache2 license, that seems like a 
showstopper.

Comments from the TSC and community are more than welcome.

Thanks… Dave
