suggestions on scaling with nginx

[amodpandey]

Hi ,

I have various upsteram configurations. I want to add or remove servers
(scale up or down) from the upstream based on some parameters. Please
provide your suggestions.

One way that I think of is to update the upstream conf and perform a
SIGHUP. Does not feel very good about it as I have to do it say 5 times
a day and it the my main LB.

Thanks
Amod
