Re: Video tear after enabling Monit

[Dylan Wood]

Hi Joost,

A few questions:

• What poll period are you using?
• What other services are being monitored by Monit?
• Does the video tear only occur when monitoring the video playback, or does it also happen time if Monit is running, but not monitoring the video playback process?
• Can you produce a top output sorted by CPU usage when Monit is running and when it is not? (http://unix.stackexchange.com/questions/158584/change-tops-sorting-back-to-cpu)
• How are you starting the process and monitoring? Is it being started from another process?
• Can you share your monit config (monitrc and config for monitoring Compton?

Hi guys,

I’m having some strange issues with Monit. I’ve tried it to monitor my digital signage players. 

The players are NUC’s running Ubuntu 14.04.3 with a full screen Google Chrome browser.

For some reason enabling Monit on these players messes up the video playback in the browser and I end up with a lot of video tear and higher CPU usage.

I find this very strange and I cannot see a logical explanation for this so I’m a bit clueless in the troubleshooting. I can provide all necessary log files on request of course.

If I play a video in the browser with monit enabled I have a average CPU usage of 80 % and bad playback / tear.

When I disable Monit and reboot I have smooth playback and a average CPU usage of 40 %.

I use Compton: https://github.com/chjj/compton

Any tips?

Kind regards,

Joost
