[zeromq-dev] not binging to all LISTEN port

[Mohit Anchlia]

I understand the basic part of performance testing and all other related
things that need to happen. I was really looking from troubleshooting
perspective. Say load increased more than anticipated or tested numbers,
when that happens are there any metrics available that can point to
router/dealer being a bottleneck. How can I really tell if I need to scale?
