After adding a host, I notice there is a vm that is missing from the list. I have deleted the host and re-added several times and even restarted the vm but I still can' t get it to appear. I see all other vm's in the host but ironically the one I want to test against. Any ideas what may be the problem?

Compare results
Hi,
I new to the I/O tool, but I got it up and working and it is spitting out results. But what do I compare the results to? Is there a list with different system configurations so I can see if my system is performing ok?
Thank you!

Change disk and Iometer not start in console
Hi everyone, im new with io analyzer, I read the manual and follow the instructions to change the disk with 100mb to other with 10 GB but when I run any workload I don´t see that the iometer start on console and only generate 40 iops on the vm in the results page. After I delete and create a new disk is necesary to do something else??
Thanks & Regards!!!

IOmeter and Wine
In the vmware appliance guide Page 29 is wrtitten than iometer is run under wine emulator.
Within the terminal window, run the following commands to start Iometer:
/usr/bin/dynamo &
wine /usr/bin/Iometer.exe
If I install iometer 2006 in windows 2008 sp1 32 bit I get better results than through io analyzer with centos and wine iomter
If I install iometer 2008 ins windows 2008 r2 64 bit I get better results than through io analyzer with centos and wine iomter

What OS does IO Analyzer use? 32 Bit or 64 Bit ? Centos ?
I thought it is Centos, but it is not ?

How to use more than 5 esxi hosts?
If i try to use more than 5 esxi hosts, than io analyzer gives a hint to use an other io analyzer controller VM.
So does this mean i will have to use two io analyzer controller vms,which means to two websites which are not synchronous?
Page 6 of the IO analyzer guide:
I/O Analyzer Configuration Maximums
I/O Analyzer 1.5.1 has been tested up to the following configurations:
With up to 128 worker VMs per ESX/ESXi host.
With up to five ESX/ESXi hosts per I/O Analyzer controller VM.
To run I/O Analyzer tests with more than five ESX/ESXi hosts, we recommend using multiple controller VMs.

Notice to I/O Analyzer 1.5.1 Users regarding "OutOfMemoryError" or "running with 5+ ESX hosts"
Dear I/O Analyzer Community,
We just recently found there is a bug in our tomcat5.5 startup script, which overrides JVM heap size to only 128M. This should in fact be the root cause of many out of memory issue.
If you are running into "OutOfMemoryError" (shown in /var/log/daemon.log) or you're planning to run with more than 5+ ESX hosts,
please increase JVM heap size for tomcat5.5 to 1.6G by the following:
- Please login to appliance
- Edit file "/etc/init.d/tomcat5.5"
- Replace line 95 from
JAVA_OPTS="-Djava.awt.headless=true -Xmx128M"
to
JAVA_OPTS="-Djava.awt.headless=true -Xms1638M -Xmx1638M" - Save the change
- Restart tomcat 5.5 by doing
`/etc/init.d/tomcat5.5 restart`
After doing the above steps, tomcat 5.5 should set JVM heap size to 1.6G, which in our testing is enough to support 10+ hosts with 256+ VMs.
There will still be a warning message when you're trying to add more than 5 ESX hosts to a single controller VM.
Please ignore the "5+ hosts" warning once you have done so.
If you'd like to suppress the "5+ hosts" warning after applying the above change, please simply login to appliance and do `touch /var/lib/tomcat6`. This should temporary work around the frontend check.
NOTE that due to the limitation of 32-bit JVM, the heap size still cannot exceed ~2.6GB. If you do need such a large heap, please be sure to increase the guest memory first since the default guest memory of I/O Analyzer VM is 2GB. (You'll need a few hundred MB more in addition to the JVM heap size for guest memory to accommodate other processes.)
Please let us know if you still run into "out of memory" issue after the above steps.
We're working on our next release, which will increase default JVM heap size to 1.6G and we'll document steps to adjust it. Sorry for the inconvenience.
Thanks,
Chien-Chia

Use the vmware fling vgc to start iometer and other windows benchmark tools
In the vgc video is at minute 4:50 shown how to start a batch file for 2 vms.
As vgc use the vmware tools to interact with vm , an advatage is for iometer test in 10 vms parallel for disk test you don't need a network configuration.
I use it i esx 4.1 . Did not trie it with 5.0 or higher.

I/O Analyzer Access Specification Files
I have followed your advice in a previous post regarding adding or changing what Access Specification file test are visible from the Web UI. I have to added .icf files to the /var/www/configs directory in the I/O Analyzer VM, however not all of them are showing up. Is there a limit to the number that the Web UI will show?
I know that it is not an issue with the .icf files as I am able to start I/O Meter from the console and load the Access specification file ok?
Is there a naming convention that is required as it appears to only be certain .icf files that are not showing?
Regards

Status stuck on 'pending'
Greetings!
I'm running IO Analyzer 1.5.1 on vSphere 5.1 and I'm having trouble running a test. I go step by step according to this video: Using the VMware I/O Analyzer v1.5: A Guide to Testing Multiple Workloads - YouTube
Though I didn't create the second analyzer vm, I don't think I need it just to see if this thing works.
Any ideas?
Thanks

Can I clone an I/O Analyzer VM before I turn it on?
I'd like to run three instances of I/O Analyzer on a three node cluster. Once I get the first deployed, can I simply clone then migrate it to the other host? Would I need to manually edit the MAC address?

IO Analyzer Worker VM - Disk Full
Hi,
I encounter an issue when performing random write tests: about 10min after the beginning of the test, all my worker VMs fall to 0 iops.
The following message is displayed on the vCenter:
Information on my my setup.
- 3 * ESX 5.5 hosts (each: 128GB RAM / 200GB SSD / 1TB HDD)
- VSAN datastore
- 4 Worker VMs per ESX (12 VMs total)
- On all workers & manager:
- /dev/sdb increased to 49GB (All workers)
- JVM heap size increased to 1.6GB (Thick eager zero)
- 1 IO analyzer "manager" on a separate cluster.
Those 12 workers use about 720GB on the vSAN datastore (so less than 1.5TB with 1 replica). It should fit easily on this 2.7TB vSan datastore.
I'm not sure if this issue is related to IO Analyzer or vSAN (beta).
Any idea ?
Thanks

Disk Error every time I/O Analyzer is deployed
Every time I deploy I/O Analyzer 1.5.1 or 1.5.0 from the OWA, the system boots, finds inconsistencies in the drive and forces a FSCK which it is unable to complete. This puts I/O Analyzer in read only mode and keeps all other configurations from working. Here is a screenshot of the error. I've tried running the FSCK manually as recommended but it never completes. I have yet to even get I/O Analyzer deployed once in my environment. Storage is iSCSI cluster through a QNAP 670 Pro. Hosts are 5.0 running through 5.0 vCenter.

Use IoAnalyzer with another OS
Hello
I am currently using I/O Analyzer thanks to the downloadable version from the website.
Is it possible to use it with a recent version of OS instead of Ubuntu 8.0.4? Or use it with another OS distribution?

Can't get Single VM Iometer test to start
Hi
I added my ESXi 5.1 host and a single windows 7 VM running on it to a workload config. For the iometer test, I selected the 128k_0read_0rand.icf workload.
After I click run, the web GUI shows that the test is running. However, I do not see the iometer console open on the analyzer. How can I debug this further (any logs, pointers etc)?
