    Evening all,

    Looking for some advice if possible please?

    Running a centos 7 box and on Friday, had a crazy high load issue with what I think was MySQL I ran

    "sar -q -s 18:00:00 -e 20:00:00 -f /var/log/sa/sa10"

    And got the following output

    Linux 3.10.0-693.2.2.el7.x86_64 (pluto.hostname) 10/11/17 _x86_64_ (4 CPU)

    Average: 18 284 31.02 26.99 26.30 17

    [root@pluto ~]#


    Clearly, there was issues between 18:40 - 19:10 (ish) but I don't how to find out what caused it / where to look in the logs.

    Can anyone help me please?

    Thank you

    Hello,

    You have to monitor server using the "top" command. The command will show the process which is causing the high load on the server.
