How do I better determine CPU usage on Linode?
I am using the Ampache open source streaming music server on my VPS (Ubuntu 18.10). I spotted two remote listeners on my admin page. Somehow them (and FFMPEG transcoding) are using 100% CPU usage (I have the $10/month plan.)
This seems really excessive. I ran two streams concurrently before with ffmpeg and it didn't use more than 7% cpu total.
What's going on?
You can run the following command to get an idea of what the top applications are that are using your CPU resources.
top -bn 1 -o %CPU | head -n 15
I'd also recommend taking a look at our Using top to Monitor Server Performance guide for more tips on how you can monitor the various resources on that your Linode has to offer.
