I'm working on this HCIBench test.  I have a question while configuring the test.

1.What are the Important components to HCIBench test results (IOPs, R/W Latency)
- Duration? Warmup time? IO Rate?

2. What is mean Latency in Result PDF?
- Average? Maximum??

3. if my test is 300EA VM, But vSAN Performan InfluxDB & Grafana result at In practice, lower Power On VMs were displayed.
Why are the results like this? have an effect on result?

I try to run HCIBench on a non vSAN VMFS datastore to compare the results with a similar sized vSAN environment. The test starts and runs for a while, deploying all the needed VMs but then ends with "vSAN Is Not Enabled in Cluster xxxx".

The fling homepage states that the fling is not limited to vSAN storage.

"HCIBench is not only a benchmark tool designed for vSAN, but also could be used to evaluate the performance of all kinds of Hyper-Converged Infrastructure Storage in vSphere environment."

I don't see any option on the fling configuration page to enable/disable vSAN.

I found an old comment from 2020 from one of the developers about the issue https://flings.vmware.com/hcibench/comments/17847#comment_17847

But the described change in code does not work, the code already has changed at the given lines. So either the code was already changed to fix this, but the fix does not work, or the change is not related.

Anyhow, does anybody have an idea how to use HCIBench for non vSAN datastores?

It's the latest version 2.8.0 from webpage. How can I get the whole config - or should I just include the hcibench.cfg from a test? I've now modified the file given in your earlier comment, but after a long runtime where it definitly ran tests it ended with no proper results.

"undefined local variable or method `ds_name' for main:Object"
"vSAN is not enabled!"

Anything more I can do?

Hi,

There are two high severity security issues on the HCIBench appliance identified by Qualys, and these are preventing me from setting up appropriate firewall rules within our environment.

QID: 730185 - Grafana Anonymous Access Enabled Detected
QID: 86728 - Web Server Uses Plain-Text Form Based Authentication

One of these is clearly quite old. Are there any plans to fix these security issues?

Hi, We wanted to try HCIBENCH in our new vSan environment. We tried 4 times but we couldn't success to finish test. Every time the progress bar is stuck during VM's disk preparation.
(Deployment Successfully Finished. 2022-11-18 10:19:40 +0000:
Virtual Disk Preparation ZERO Started.(May take half to couple of hours depending on the size of VMs deployed
2022-11-18 14:17:43 +0000: Disk Preparation Finished: 0/24 VMs)

we are using default simple settings with easy run 4K/%70READ/%100RANDOM. It has been still at 0/24 VM for 20 hours.

What could be the problem.

this issue was addressed, turns out this was due to vsan misconfigurations.
