Are there tools or utilities to understand about the reason behind high load on CentOS Linux.
Please help me understand with examples.

How did you know there is a high load in the first place?
Using “w” command
First and foremost…”top” is your friend.
The load average has relationship with I/O.
If you have RAID system, check what the status says you. You might be on
a degraded RAID (broken, rebuilding,…) eating much disk I/O.
in addition to the solution provider by Mihamina to monitor the load
average on your server, “htop” on CentOS can be more clear for you to read
the output as well.
install rpmforge repo
yum insall htop, type htop when done. look ay load average figure. then
find out the cause.
Thanks / Regards
I would define load as the number of processes who are waiting to get
While a process is waiting for cpu there are 2 cases:
a) the cpu is blocked waiting for a I/O operation to finish
b) the cpu is calculating for another process
I should have said “statistically, I have noticed…”
I missed precision.
