monitoring - detecte playback lag

[Thuzad 50]

Hello,

I try to detect when there is a problem loading on a person reading a media.

I am currently monitoring the transcoding position of each playback and I can tell if there is a transcoding problem. I'm watching if the transcoding position relative to the playback is less than 5% for more than 5 minutes.

But sometimes it happens that the server is overloaded in I/O and CPU and even the plays that are done live (so without transcoding) don't load anymore and show a loading logo for a few moments.

How can I detect a lag on my server and the fact that the readings no longer work? 

Best regards,

@chef may have some tips.

Hi, how are you monitoring the rate of transcoding now? 

[Thuzad 50]

I use Zabbix and I monitor the following values via the API:

• TranscodingPositionTicks
• PositionTicks

But I'm trying to find out when there is no transcoding if there are loading problems due to a server performance problem.

up @chef  ! Thank you

Do you have thottling enabled for transcoding?

[Thuzad 50]

Yes but when I have too many streams and a lot of CPU usage my website can sometimes freeze. And I'd like to detect this with values that I can retrieve, be it logs, API data...

 

I have active monitoring on the CPU but it is difficult to activate alerts based on it, because of the transcoding that causes large CPU spikes.
