I am running a laravel application on a Ubuntu 14.04 digital ocean vps and I am using New Relic to monitor the server.
I got an email alert that my CPU usage was above 80%. I logged in to New Relic and now it's showing my CPU usage at 99% for 18 hours now. But when I log into my shell and run 'top' the CPU usage of the processes don't even sum up to 10%.
What could be wrong? Which are other commands I could run to check the real usage and what is using it so much? (Perhaps an infinite loop on the application?)
This is my htop result:
And this is htop after shift+K
Any links or help would be greatly appreciated.
