Hi,
Thanks for the update to 1.6.
For Linux deployments I have set the kernel disk scheduler to noop. My thought is noop would just queue everything and send it to the array with no assumptions. VMware has a KB for this in regards to 2.6 kernels and I have set this on SLES for VMware as well running a 3.* kernel. Is there a recommendation either way on this for the analyzer? Thanks!

For those of you like me that want to use a static IP on your worker VMs, cant find how to set that up in the documentation and are not all that familiar with SuSE here is how I did it.
Hope this helps
We have run vscsiStats to measure our current production workload and wanted to simulate that same work on a different IO configuration. We have noticed that it is not possible to distinguish between "drives/LUNs" per VM and per host. It seems that you can only replay at the "host level".
Therefore, we are reverting back to running several IOMETER sessions simultaneously across the VMs on multiple hosts in order to simulate the IO activity that we captured from our production environment. We don't want to just "replay" vscsiStats "as is" because our configuraiton on the "back-end SAN" is different than what we have in production. We want to test out RAID 10 vs. RAID 5 and different SAN pools of "mixed drive types- e.g, NL-SAS, SATA, SAS, SSD". We are executing on EMC VNX storage arrays. Any suggestions are welcome.
Just downloaded and trying to setup the I/O Analyser tool.
Failng at the first hurdle 'Adding Hosts to the I/O Analyzer Host List' put in the IP and root password into the webpage and get no further button says 'adding' page hangs.
Tried using esxi5.5 and esxi5.0 hosts.
Browser is firefox on win 7 anyone know how I can troubleshoot?
Any chance we could have the ability to add a non vm dynamo for comparison? It seems like everything is mostly in place to do this, we'd just need a few scripts added to select, control, parse, and display the results via the web interface.
Hi,
I think this is a bug in IO Analyzer V1.6:
When I configure a test with low test duration (<120sec) then I get the question "Recommended duration is at least 120 seconds. Would you like to submit anyway?"
So when I click "cancel" the test is run anyway.
I use Firefox with Windows 7.
Hi all,
i deployed the io-analyzer 1.6.0 as a controller without any workers in our vpshere 5.5u1-environment, but i am unable to collect any guest-stats. Iometer does not popup. The analyzers second disk has not been edited and all settings are default. Running iometer from the analyzers desktop manually is working. I can ssh into the analyzer. The logs in /tmp/run-iometer.log and /var/www/ioa.log are empty.
/tmp/ioa-daemon.log states:
sh: -c: line 0: syntax error near unexpected token `('
sh: -c: line 0: `perl /root/ioAnalyzerScripts/copy_to_server.pl (Controller) /tmp/configInfo-local.txt /ioa/configInfo-local.txt'

sh: -c: line 0: syntax error near unexpected token `('
sh: -c: line 0: `perl /root/ioAnalyzerScripts/copy_from_server.pl (Controller) /tmp/iometer.csv /tmp/iometer-VMware.csv'
head: cannot open `/tmp/iometer-VMware.csv' for reading: No such file or directory
grep: /tmp/iometer-VMware.csv: No such file or directory
rm: cannot remove `/ioa/tracereplay.conf': No such file or directory
Any hints?

Hi!
I was downloaded the zip file, but I can not unzip, because the zip is corrupted.
Dear I/O Analyzer Community,
We've just released a minor update release for I/O Analyzer, v1.6.1.
This minor update includes:
* Changed guest I/O scheduler to NOOP and disable I/O coalescing at I/O scheduler level.
* Downgraded VM version to 7 to be compatible with ESX/ESXi 4.0.
* Back-end improvements to workload generator synchronization to support 240+ workers.
* Bug fixes.
This version also includes a configuration generation script for trace replay tests. We will publish a separate document to describe how it works and how to use it.
Thanks those who have reported bugs and kindly provided us log files for debugging.
Please let us know if you run into issues with the new release.
Thanks for everyone's support,

Dear Community,
In I/O Analyzer 1.6.1, we have included a script, traceReplayConfigGen.py, which generates a trace replay configuration file for a large number of worker VMs. This document describes the usage of traceReplayConfigGen.py.
Please let us know if you run into issues when using traceReplayConfigGen.py.
NOTE that the script is completely experimental. We are planning to improve our web UI to support adding worker VMs with regular expression. Since web UI change might take time, this script is meant to be a temporary workaround.
Thanks for everyone's support,
Chien-Chia Chen
I/O analyser is built on SUSE linux with an internal hostname of `localhost` - not the name you see in the vSphere client.
When it self-registered `localhost` in the Windows DNS the second time it was started this afternoon it swiftly became a focus of attention for Group Operations.
Unsportingly, they deleted the record!
I had to 'fess up - at IT director level.
Doubt I'll be invited to their Christmas party.
Kindly note to the I/O Analyser `flingers`: pls give it a hostname. `vmioa` would suffice.

Hi,
I've downloaded and deployed IOAnalyzer version 1.6.1, and i'm having issue getting IO meter to run.
I've followed the installation instructions and done a bit of searching, and still cant get it to work.
I have added a DHCP scope and once the VM has booted and registered, i then give the VM a reservation and allowed for a host name to be given. Ive updated my DNS records and can resolve all IO Analyzer VM's with all reporting Round trip latency well below 1.5 seconds.
I can SSH into each host, and other workers using host names. (From each IO Analyzer VM via terminal)
I've even removed all other workers and just have one controller acting as a worker, and i still cant get the Web UI to launch IOMeter if i watch the console.
I can however, from a a terminal : /usr/bin/dynamo, then launch IOmeter and start a test manually.
Im lost as to what could be the issue, can anyone help ?
Hi,
I just downloaded version 1.6.1 and I was surprised that it was 2,8GB large. Is this huge size really necessary for an ova file?
Hello VMware experts,
Hope you all doing great... i have a question, i want to implement this VMware I/O Analyzer for monitoring the LUNs which is connected to 3 node Microsoft SQL 2008 R2 cluster.
3 HP blades - running Microsoft Windows server 2008 R2 OS (NOT ESXi OS) - 1 MS SQL Cluster
Hi, I have installed vmware-io-analyzer-1.6.1 and as instructed I have deleted and add a 200 GB second hard disk. and then I have changed the ip address. Also I have installed 3 more to put more load on storage. I could not able trace any load.
when i open IO-meter I could able to see any thing. Can some one assist on this please. I would like to check maximum number of iops on my new storage.
there are I/O in hardware parts such as (storage, memory, network, CPU)
But mainly what is I/O mean?
I need easy explaination. any one?
Do you have any assessment of, or remediation for, the vulnerability of this appliance to the various Shell Shock CVEs?
Dear I/O Analyzer Community,
We've just released an update release for I/O Analyzer, v1.6.2.
This update mainly includes patched base OS packages to address security vulnerabilities including Shellshock. Although I/O Analyzer shouldn't be affected by Shellshock, it is still highly recommended to update to this version as soon as possible.
This update release also added additional warning messages when invalid VM names are detected.
Thanks those who have reported bugs and kindly provided us log files for debugging.
Please let us know if you run into issues with the new release.
Thanks for everyone's support,

Hi, I have a rather quick question.
If all the tests are based on IOmeter simulations, is there a list of all tests and their configuration specs available somewhere?
Hi,
I am trying to login into the appliance with root / vmware but I am getting an authentication failure, I can login with vmware / vmware but this does not give me root privileges as I need them to provide static IP info.
anyone knows the updated root password?
Thanks,
Harold
