    Hi

    I am getting a system load of 90 and i have a lot of free ram swap i not used at all and cpu is high about 90% but i am sure that the problem is from a background system command that can't be found using top :(

    Using top all are normal and i have very low numbers as always....


    I am not also under attack for sure as i don't have many connections on the server...

    Is there anyway to check with more details what is causing this system load?

    Maybe an application task is running or maybe a task crash?

    After restarting the server is fine now but just to know for the next time...

    Thanks

    start with my mysqlmymonlite.sh script at mysqlmymonlite.sh Addon | Centmin Mod Community it's basically a lite version of the full version I use for my paid optimisation consults I do with clients :)

    Official site page is at mysqlmymon.com and the web site lists an example output of what type of server info and stats the script gathers.

    readme.txt in zip for mysqlmymonlite.sh has instructions for setting cronjob to run script to gather output and save to disk log file or email you every X interval where X can be every 5-15 minutes or every hour. So you do not need to physically present to catch the high load situations.
