Useful to indicate when to scale?

[roccomuso]

Hi guys,

Someone using this in production?

For istance, how do you know based on the process usage when it's time to scale up an application?

Thanks.

I use it mostly for benchmarks or monitoring.

You could easily keep process usage statistics and then compute to see if you need to scale.

@soyuka you're right.

I'm trying pidusage under windows. The used memory is around 40MB per process. The cpu_usage always shows me 0. Is it reliable?

[soyuka]

There has been many discussions around windows, I'm looking for better ways.

For now it spawns wmic (https://github.com/soyuka/pidusage/blob/master/lib/stats.js#L135), and I find it slow and dirty. So, yes according to wmic spec, it should be reliable. If it's efficient, I won't vouch for it on windows.

If you have any idea on how I could improve the windows part please let me know! What's hard is to keep it portable (see #10 #9 #7)

I see.

Well, at least on my Linux servers there shouldn't be issues. 👍

No worries on linux, except if you want to compute child processes ;).
