            mySQL using 100% CPU
            Asked 2020-Oct-30 at 09:55

            I have a PHP application that is running on a LAMP stack. This application makes an API call back to the server via javascript to get more data to display on the screen every second. When there are a number of users using it at the same time, say 80, mySQL slams the CPU to 100% until the application is finished.

            What am I using:

            • mySQL 5.7.31
            • Ubuntu 18.04

            Running on an EC2 instance of size m5.xlarge

            • 4 vCPU
            • 16G RAM
            • network BW up to 10Gbps

            I used advice from percona about tweaking the mySQL parameters, they say most of 5.7's have great defaults expect a couple that are dependent on your hardware, so my mySQL config looks like this

            Forget mysql tuner - it will likely do you more harm than good unless you already know what you are doing.

            For the first two queries in your QAN screenshot, you need an index on stored_path_data(stored_path_ID, tick). That should make a huge amount of difference to the performance and CPU consumption.



            MySQL 5.7: fine tuning for too many connections error

            I noticed you SET Open Files handles in ubuntu to 1024 when you ran ulimit -n 1024. Your system needs many more available Open File handles to support your 4650 innodb tables. Suggestion ulimit -n 24000 and then check settings with ulimit -a (to list current limits). I am looking forward to analyzing your data next week from production instance.

            Suggestion for your ulimit -a to consider please

            ulimit -n 24000 # from 1024 to enable more OS file handles to be active.

            The above is dynamic with Linux OS. Stop/Start services would have access to the handles. To make this persistent across OS shutdown/restart, review this url for similar OS instructions. These instructions set 500000 for the file-max, please set your capacity at 24000 for now. ulimit please set to 24000, which will allow MySQL to use requested limits and have spares for other apps
