Why do I get these when server is 16 cores with 2T storage?

There are many possible reasons for the sudden full load of the cpu, the most common one is caused by the cc attack; The troubleshooting steps are as follows: There is a [Task manager] plug-in in the software store, you can open it to see the processes with high CPU usage; if you have not purchased it, you can use the htop command to analyze #centos yum install -y htop && htop if(window.hljsLoader && !document.currentScript.parentNode.hasAttribute('data-s9e-livepreview-onupdate')) { window.hljsLoader.highlightBlocks(document.currentScript.parentNode); } #debian/ubuntu apt update apt install -y htop && htop if(window.hljsLoader && !document.currentScript.parentNode.hasAttribute('data-s9e-livepreview-onupdate')) { window.hljsLoader.highlightBlocks(document.currentScript.parentNode); } or top command analysis If it is mysql, php, nginx, it is recommended to check the website log to see if it has been attacked, or if mysql, php have a large number of slow logs, and if so, contact the programmer to deal with it for you; If you can’t analyze website logs, the software store has [Website statistics v2], which can be used to visually check the logs to see which website requests and accesses are currently abnormal. If a large number of requests come in within 1 second or a few seconds, there is a high probability of being hit. Yes, you can install our [nginx waf] plugin to block attacks Open the Nginx WAF, check whether there is an attacked record, try to adjust the cc defense rule of the Nginx WAF to enhanced mode, and see if the cpu has dropped.

aaPanel_Kern what does these logs mean?

aaPanel_Kern

Hello, did you set these tasks manually?

Aap_Sidney

aaPanel_Kern Yes I set them manually. I use supervisor and cronjobs

aaPanel_Kern

Hello, is it because the time interval between command execution is too short?

Aap_Sidney

aaPanel_Kern The time intervals increase the CPU consumption?

aaPanel_Kern

Hello, yes. It is recommended that you check how long it takes to execute this command and whether data is written frequently.

Aap_Sidney

aaPanel_Kern I think it is not normal. I use the same script and the same command on cpanel and do not get this. The cpanel is installed on 4 cores and aapanel is on 16 cores. Something maybe wrong somewhere that consumes many resources.

aaPanel_Kern

Hello, you can check the load status from the monitoring interface and check whether the website is under attack.
The homepage prompts that software is being installed.
