bash script to monitor OpenVZ containers

VPSnet

Hello,

today on one of my clients server i was searching who loads disk read and write, there was lot of containers so i created small script to monitor it.

By request i can add any type of resource print to putty (even network statistics like mails/s, udp packages, tcp packages, fyn packages, syn packages and so on)

There is the script:
https://github.com/bacarrdy/openvz-monitor

I created it only few hours ago so there can be some bugs, but form me it worked.

This is only example, i cerated it only for disk read/write, but later in few minutes added other resourses like hdd usage, ram usage, cpu usage

Why are you using vzctl exec? You can easily get resource usage using vzlist.

i can get limits, but not real usage. And i dont know a way to get for example CPU usage with vzlist

Yes with -j option you can extract some values, ill change it for thouse resourses like memory, disk usage, or load averages

Vzlist -j gives you pretty much everything
