Need help on explanation of Avg. Disk Queue Length

Based on perfmon, my Avg. Disk Queue Length on physical dick hit 100%.
What's that mean? Really need explanation

I’m a bit confused by your statement. I'm not sure where the 100% is coming from.
Avg. Disk Queue Length is the average number of both read and write requests that were queued for the selected disk during the sample interval.
Current Disk Queue Length is the number of requests outstanding on the disk at the time the performance data is collected. It also includes requests in service at the time of the
collection. This is a instantaneous snapshot, not an average over the time interval. Multi-spindle disk devices can have multiple requests that are active at one time, but other concurrent requests are awaiting service. This counter might reflect a transitory
high or low queue length, but if there is a sustained load on the disk drive, it is likely that this will be consistently high. Requests experience delays proportional to the length of this queue minus the number of spindles on the disks. For good performance,
this difference should average less than two.
This whole topic can get very confusing.
Think of Current Disk Queue Length as in flight operations.
These are disk read or write that have passes through the Performance Filter Driver and are on their way to the physical disk and back. While in flight a disk activity must pass through (Assuming a SAN) your class drivers, multi path drivers, HBA card
the network fabric, Switches and into the SAN. Any of which could introduce a bottleneck.
Then the acknowledgment of completion must return.
Think of Avg. Disk Queue Length as disk activities waiting to jump onto the flight.
So if you have an Ave. Disk Queue Length happening thinks of this as cars backing up on the on ramp to get on to the highway.
Typically I start disk analysis by looking at:
Logical Disk\Ave. Disk sec/Read
Logical Disk\Ave. Disk sec/Write.
The Queue Length counters are secondary and only used if the latency counters are out of spec.
Here are some good Blog and tools to use to follow up.

Disk Queue Length ?

Our organization is having some slowness problems particularly when most are logging on and off so
mornings and 330 or so I've been through everything bandwidth etc we have 10G switches but I've come across this I believe is the problem on our server that we redirect everyones desktop and profile etc. On that drive in he resource monitor there is a section
for Disk Queue Length that I've read should be 0-2. Ours averages 5-10 and spikes to 50 during these slowness times. All our servers are VMware, its on a SAN with SSD drives so what can I do to resolve this. Its just on the drive that that data is on so we've
been considering creating another drive and splitting up the users profile folders or do we need another separate server? How can I fix this problem? Is there a limit to the amount of users that can be setup to access one server? Do I need to break that up
to several servers?

Hi Jason0923,
The Disk Queue has Length may caused may reasons, such as high workload with SAN IO bottleneck, generally we can first confirm whether your SAN write disk cache has enabled,
others clue is you can refer the following article to determine whether there have IO bottle neck with your SAN.

VM exhibiting 100% disk busy time, large disk queue lengths

Hi everyone,
We have a .VHD workload residing on a logical 2 x 136Gb RAID1 mirror pair of disks.
The .VHD file is 130Gb (with 70Gb of free space)
The Virtual Machine is running Windows 2008 R2 SP1, 4 cores and 8Gb of RAM and is exhibiting 100% disk busy time and disk queue lengths of anywhere between 14 and 44
I'm assuming this is because there is virtually no disk space on the logical drive. Ops Mgr 2012 R2 reports high memory pages/sec
So we backed up the .VHD workload, broke the RAID1 Mirror and inserted 2 x 300Gb as a RAID1 mirror and restore the .VHD / VM
The Logical disk has 50% free disk space, however the VM is still exhibiting 100% disk busy time and the above disk queue lengths.
It is running on a Windows Server 2008 R2 SP1 HP Proliant Server running the Hyper-V role under Server Core
Any ideas most appreciated.

Hi,
The mirror array doesn’t improve the disk performance but only for the disk redundancy, base on my experience some application frequent operate the large small files often
can use the large disk resource, if you can’t sure the high disk IO cause by the guest vm or host computer, you can use the Resource Monitor first to identify which process handled the high disk resource, then do the further troubleshooting:
The third party Resource Monitor use example:

Need help returning (not printing) avg GPA from array??

Here's what I have so far. After returning the value then I gotta print the avg in a separate method. I also need to check the names of the first and last student using an "equals" method. Please someone help with whatever you can. Here's what I got:
import java.util.Scanner;
public class StudentLists {
//Main method. Prompts user for the number of students.
   public static void main(String[] args) {
   Scanner in = new Scanner(System.in);
   System.out.print("Please enter the number of students in this class: ");
   int s = in.nextInt();
   Student[] students=new Student[s];
   FillStudents(s,students);
   printAll(students);
   public static void FillStudents(int s, Student[] students){
   for (int i=0; i<s; i++)
        Scanner inf = new Scanner(System.in);
        System.out.println("Please enter student's first name: ");
    String first = inf.nextLine();
    System.out.println("Please enter student's last name: ");
        String last=inf.nextLine();
        System.out.println("Please enter the number of credits completed: ");
        int c=inf.nextInt();
        System.out.println("Please enter student's GPA: ");
        Double g=inf.nextDouble();
        students[i] = new Student(first, last, c, g);
    public static void printAll(Student[] students) {
    System.out.println("Names      Credits GPA");
     for(int i = 0; i < students.length; i++)
    System.out.println(students);
public static Double getAvg(Student[] students, Double g){
double sum=0.0;
double avg=0.0;
for(int i=0; i<students.length; i++){
sum+=g;
avg=sum/students.length;
return avg;

Oh no I wasn't giving any orders. I was saying I have been trying to edit what I have, but I can't figure out how to get the method right to do my average of the GPA from the loop. I don't know what to put in there. I was just asking if you would write it and then kind of explain what u did for me please.

Replaced hard drive in compaq presario cq62, need help recovering it with out disks

Recently replaced the hard drive in my notebook due to failure of original. Need help recovering it without disks

If you are wanting to install the original copy of Windows it came with, you will need a set of recovery disks.
Otherwise, you can purchase a copy of Windows to install and download the appropriate drivers from http://goo.gl/hOm3. Just make sure the copy of Windows that is installed is at least the same family of Windows to ensure that drivers are available.
What is the exact model of the notebook and product number?

I can't see a button on the chat page, to get help. Java script is enabled on my Mac. what can I do?

What exactly is the problem?
You could download the 30 day free trial using the link below - It‘s the full product. If you get it successfully installed simply enter the serial number from the DVD box into the trial and it becomes yours to keep. No further installation is required from disk.
Uninstall first, then download.

I need help choosing a different startup disk

I've recently replaced my MacBook hard drive, and am now unable to choose a partitioned section for my startup disk.
I created two partitions on the new hd, then copied all files from my old hd onto one of the partitions. Everything works wonderfully...as long as the old hd is attached as an external hd. System Preferences->Startup Disk shows only the old hd and a network as an option. The new hd does not appear in the Startup Disk at all.
I've restarted holding down the option key with the same result. I can choose from the old hd or EFI (which does nothing). If I detach the old hd while the power is off, I am given no options on restart. Mac just freaks out.
Any help will be greatly appreciate.

Hi
I created two partitions on the new hd, then copied all files from my old hd onto one of the partitions
You can't do it this way. A large part of what makes your OS System bootable is the underlying Unix Structure. This would not have been copied. To facilitate a bootable copy you can use a number of methods. Disk Utility > Restore will do it for you as will CarbonCopyCloner. Both of which are free. If you want to spend money SuperDuper is something you should consider.

Need help with basic user events in Queued state machine example

I have written a little queued state machine example to try to teach myself about creating and using user events. The objective of the machine is to periodically choose a number (I'm doing it now with a control instead of a random number generator for troubleshooting), and compare that number with the number I have set in a control. When they match, I want to cause an event to fire so I can do something about having found a match. The examples in the LV Help file references show the events within the event structure, but I want to reach out of a state and cause an event ....
Can someone point me in the right direction here?
Thanks

User Event Generator Example01 snip.png ‏102 KB

Yep....That was it...I had tried to do that but got fouled up with the variant definition...so defined the user event using a boolian and did the same in the case structure where I wanted to create the event and it worked great...
Thanks.
Here is the final version...not bulletproof, but does have a queued state machine using a user event to cause an event to fire.
Hope you find it useful.

Need help on implementation of a circular queue with fixed size

The constructor of the queue is as below:
RingBufferNode[] element;
RingBufferNode firstFree;
RingBufferNode firstFilled;
public RingBufferQueue (int n) {
          element = new RingBufferNode[n];
          for(int i=0; i<element.length-1; i++){
               element.next = element[i+1];
          element[element.length-2].next = element[element.length-1];
          element[element.length-1].next = element[0];
          firstFree = element[0];
          firstFilled = firstFree;
     }class RingBufferNode {
     public Object value;
     public RingBufferNode next;
     public RingBufferNode (RingBufferNode n)
          { next = n; }
}Each node in the queue are expected to have a pointer "next" pointing to the next node in the queue, where the last one will be pointing to the first. When I called the constructor to create a new RingBufferQueue, the following error occurs:Exception in thread "main" java.lang.NullPointerExceptionI've tried to throw the exception however it seemed to be a useless move.
Edited by: ewrhgqerh on Dec 11, 2008 5:31 PM

Sorry don't quite get what you want me to post, I'm a starter. It's not using a stack, but a queue instead. And the place where the compiler flagged the error is this line:
element.next = element[i+1];

Need help with explanation of FRAPS to Adobe Pre Elements

Hello Everyone.
So I'm having this issue and its really holding me back. I am a complete hobbyist when it comes to editing and I'm trying to solve my issue where my fraps footage looks like garbage once imported into Adobe Pre Elements 9.
Now I wanted to get a newer version of Adobe because it seems to be a good starting place for me to get more into editing and its the only program I'm familiar with so I went ahead and bought Elements 11.
My settings are fine and I have made a post before about my issue and I have found the simplest answer I could find. but it makes no scene to me . I have no idea what a codec is and how to work these programs. I am looking for someone to explain to me what I have to do to keep my quality from fraps and import it into adobe and when its exported to actually look like its a 1080p Movie rather than what I'm having.
example movie of what the quality I have now...www.youtube.com/watch?v=8pJ8fl_g5R
I have watched a number of videos on what my settings and render out settings should be and they are correct.
This is the answer I found http://forums.adobe.com/thread/967201 Can someone explain this to me?
I am also considering XSplit is there similar problems with that recording program to with Adobe Elements?
would really appreciate a answer here rather than rummaging through threads because I am very new with the terms and end up not understanding how they solve the problem.
Thanks.

FFDShow is a "direct show" video application. Once, going back many years, Premiere (before either Elements, or the Pro versions) once used direct show for display. At about Premiere 5.0, that was changed, and Premiere began using its own display module. FFDShow is available from several sources, but many users of both PrPro and PrE have had issues with it, and it is usually tough to remove from a system. However, one trusted user and contributor here, Neale, found that FFDShow did help with some display problems on his computer, and some claim that Adobe T/S does recommend it, in some cases. Based on the problems, that so many others have encountered with FFDShow and several Adobe programs, I steer clear of it.
A video screen-cap program will capture at the computer's full screen resolution, or some portion of that, so if one has, say 1920 x 1080 for the display resolution, that will be the default capture resolution. What is stated by other posters is probably THEIR computer's screen resolution, and yours might well differ.
The HuffYUV CODEC is available free, but it is now rather long in the tooth. Many feel that the newer Lagarith Lossless, or UT Lossless, are better options, and both are free. In their cases, one would Export/Convert to MS AVI, but using the Lagarith, or UT CODEC, inside the AVI wrapper. It has been so long, since I last used HuffYUV, that I cannot recall if it was also wrapped in the MS AVI container, or not - just too long ago.
For more background on CODEC's, first see this article: http://forums.adobe.com/thread/440037?tstart=0 For even more info on CODEC's, see the link in Reply # 8.

Need help with Error message "The disk you inserted was not readable by this computer"

I got this message this afternoon "The disk you inserted was not readable by this computer" with the options to either "Ignore" or Eject"
This is in reference to my External Hard Drive "Buffalo" 1TB. I just got my Mac 27inch this week and when i got it i hooked up this hard drive to it, historically used on my old windows machine, but was still FAT32 formatted. I was able to upload all my pics to Aperture and music to iTunes. Was able to surf the data no problem.
This afternoon i noticed that it was no longer visible in the "Finder" and afre rebooting several times, got this message "The disk you inserted was not readable by this computer"
Neither the mac nor the HD was moved since yesterday, early this am when it worked.
Is there an easy fix to this? whats going on.
Some info:
I had used this external storage unit for more then a year.
I sold my PC today so cant test if the hard drive still works on that.
I have the latest 27 inch mac (2.7GHz)
Storage is connected to a power source ( I tried both USB and FireWire, both yield the same message)
Any advice?

Need help connecting to my usb disk via wan

Hey
Ive manage to connect to my usb disk in my own wifi network but when i try to connect to it through Safari using afp:// myip:chosenport it will not work, why doesnt it? I think ive checked all boxes in Airport ultility to make my disk avalible.
Could some friendly soul make a guide so i know if im doing anything wrong with my settings?

I see my usb-disk in the sidebar when i open Finder, if thats what u mean?
I should have the latest update with Mountain Lion so i suppose it would support it? And yes i am using an Airport Extreme router!
When i try to connect through Finder->Go to Server and-> writing my ip and connecting, the connection takes about 1 minute to say that the server is not avalible at the moment or something like that!
