Bandwidth Monitoring Alert firing incorrectly Question Question
My droplet has no bandwidth data in its Graphs whatsoever. Why is that? Question Question

Question

How does my CPU usage suddenly peak ?

Posted April 18, 2019 2.6k views
MonitoringUbuntu 18.04

Hi,

Ubui am running an ubuntu 18.10 on a Droplet with enabled monitoring and have set it to notify me when CPU usage is higher than 80% for testing purposes.

What i noticed is that there was a sudden peak of 89% CPU Usage while the machine is powered on however not in use so i wonder if there is a way for me to know what processes have exploited CPU %?

Is this normal behaviour ?

Respect

Greetings!

It’s hard to say what it could be, it’s not particularly unusual. Perhaps someone tried a strong and distributed brute force attack against a public facing service. Perhaps you have a web server running and a crawler came along to hammer away at it.

If I ever need to get down to that kind of level and find out what happened at a specific time, I usually prefer syssnap to do the job. It’s made by cPanel but by no means requires their other software to be installed.

    Thanks for your answer and suggestions Jarland,

    the situation is i have installed only GO lang with only 1 hello world printiln script and Yarn on that droplet.

    I was not using the machine and was not connected to it during the time when i received the alert. It says that local disk usage(read/write) was increased and droplet memory is up for 10%.

    I dont know if some automatic updates are enabled by default when instantiating a droplet, but i would like to clarify this behavior so i would not get surprised when i need to run monitoring for a more serious solution.

    Any guidance is appreciated,
    My best
