Linode emails about CPU consumption exceeding threshold?
I keep getting these email notifications saying that my Linode has exceeded the notification threshold for CPU Usage by averaging over the limit that was set for a given time period. I have tried debugging to see the cause, but can't seem to figure out what is causing my CPU Usage to be high. Any ideas what might be causing this?
First off, thank you for being so diligent by attempting to resolve the issue independently! I would like to preface this response by saying that exceeding this threshold is not necessarily anything to be concerned about, and it may just be a result of the type of activity you are using our services for.
In the event that you would like to modify the actual notifications that you are receiving, I would reference this documents page which talks about how to change the specific settings which alert you by email.
Beyond the actual notifications, I can also help by providing some resources that may reveal the source of your resource consumption issue, which would ultimately stem the flow of these emails.
I would recommend starting by using the "top" command to identify running resources and their resource allocation:
top -bn 1 -o %CPU | head -n 15
Following this, I would encourage you to read through our community post, Why is My Linode Using 100% of Its CPU?. There is a ton of great insight there which may help you identify what the cause of the issue may be.
