Hi,

I have one issue in the Linux server.


DiskBusyPercent :
==================

Disk_Write_Percent>90.00 OR Disk_Read_Percent>90.00

Disk_Read_Percent=100.28



How to check this Disk Buzy percent in Redhat Linux 6.1 ?

What could be the possible causes for this Disk Buzy percent?

How to resolve this issue ?

Any help....please.......

Where are you getting this now? And why don't you use that same command on RHEL6?
The disk is busy, because something is accessing it. Wouldn't it make sense to check your currently running processes, to see what was doing it? Have you looked at sar, pidstat, or iostat??

And, as has been said to you MANY times...have you contacted Red Hat support??? You are using RHEL, so you get access to support with your paid-for subscription, right??? They can help you with such things. Again, you rarely post follow-ups, answer questions, say thanks, or even bother to mark threads solved, or share solutions...so why should we continue to help you?

Hi,

If you can't help me, kindly keep ignoring my questions.

Don't bother about my queries....please....

There are many people in the world who are ready to help me....

Please don't give helpless replies.....


I will give answer to the question i have posted...

see here ...and this solution i got from somebody who helped me online in some other forum....


if it is useful for you ..please take my help.....i like people helping and not like you....

SOLUTION TO THE QUESTION I HAVE POSTED:
=========================================

- iostat can provide the values
- A graphing tool like cacti or collectd can collect those and show trends
- and a monitoring tool like nagios, xymon can alert if thresholds are reached

Cause of disk utilization is...
programs need IO for their tasks

How to resolve:
Investigate what needs IO and why and in which way.
Then either optimize the config or spread the load (e.g. use different spindles for logs, input data, output data or add more discs/controllers or use more machines)

I DID help you, but you apparently didn't read/understand it. Did you not read this:
Did you not see that I mentioned THREE UTILITIES to help you check it?
People have been spoon-feeding you here for quite some time, myself included. AGAIN, you rarely post follow-ups, answer questions that are asked of you, or even say thanks. Why should anyone continue to help you, when you behave like that?

I even asked you what you used to get the statistics you posted initially...yet you didn't answer, and still haven't. Do you not see a pattern there? How about some of your previous posts:

...where you can't even try to look simple questions up? As you said..."Please don't give helpless replies".
Wow...congratulations...you got the same answer I gave you...again, I told you about iostat in my first reply. And yes, any monitoring system can ALERT you to what's going on, but you then have to go fix the problem.

Glad it was so much help.
