Linode Thank goodness for glances - cpu steal

Colin · Jun 19, 2017

I've said it before, but given these things creep up on us...

Thought the site was being a bit 'laggy', opened a console and found my screen>glances session. Whilst not the root cause, it's a little pointer for a php/mysql app.

This would be the third noisy vps on linode in 4 months, it's a 24gb one too, so not cheap overloading 1g ones.

It really is driving me to the jaws of a dedicated. I'm not going to pipe it to another host with 40odd mins of downtime, it feels like it's an increasing issue, random too of course based on node distribution.

Anyhow if you run a vps, run screen and glances too. This steal isn't shown on most of my other monitors, well free ones

probably a good correlation between folks choosing larger Linode VPS plans require and actually more likely to use up that cpu time.

Interesting which linode datacenter ? top command also shows cpu steal = st field as does sar -u command with historical records

example Linode Singapore VPS's cpu steal for past 24hrs averaged = 3.38%

Code (Text):

sar -u | sed -e "s|$(hostname)|hostname|"
