My newly installed server justr went mad
all of a sudden the cpu and Disk IO are all in red cpu 100% Disk IO 99.5 filly used up

thwe server has only two accounts which hardly have any traffic

  PID USER      PR  NI    VIRT    RES    SHR S  %CPU %MEM     TIME+ COMMAND

Can any one please offer a solution to this

thank you

Nothing there shows 100% CPU or high memory usage.

The top process (PID 19881) is only at 11.8% CPU

kworkers are multiple httpd instances, which is normal for a web server.

Watch your server with htop for a while to get a sense of your avg. CPU usage. Also install Netdata (under Graphs in CWP Admin) if you want to build graphs that show your CPU, memory, disk IO usage over time.

Kindly look at this

the disk IO is completely used up and no site are loading the two sites on the server are too slow or fail to load at all

thank you

run iotop in a terminal, or use Netdata as I suggested.

Code: [Select]

sudo iotop -p PID

Those 2 graphs are never accurate.

Run & past htop or mpstat from the CLI.

htop will show CPU Usage, and mpstat will also show Steal % if you are running a VPS.
