Would love a swarm_complete event

[nstielau]

Hey,

What I really want is to output a JSON representation of the swarm (and nothing else) to STDOUT upon completion. It doesn't seem like the hooks support this at present. Perhaps a swarm_complete hook could accomplish this.

Thanks! Great stuff!

Hi nstielau,
Not sure I follow, how would this swarm representation look like?

Hey,

I want the stats info as JSON. So this final output

INFO:locust.core:All locusts dead
