Anyway, 1)the file of state.html(this file will show the performance data with
diagram)is not found in directory of "iotest-vdbench-**vm"
At the same time,2)the CPU USAGE and RAM USAGE could not correctly show in file of "vdb-**-**-**res" as the following:
Resource Usage:

which version you are using? are you testing on vSAN?
could you look at the /opt/automation/logs/io-test-xxx.log and paste me the err msg inside?

HCIbench version is 1.6.3
Yes,it runs on vSAN.
I could find the file names 'io-test-vdb-5vmdk-90ws-8k-30rdpct-50randompct-10threads'.
It seemly found the following err msg:

I would recommend to use the latest HCIBench. Whats your vSAN version btw?

Jul 15, 2020

vSAN version is 7.0

Jul 15, 2020

I would recommend to use the most recent HCIBench because we had rbvmomi upgraded in this version to accommodate the new devices introduced in 7.0.
Try 2.4.0 and let me know if that works for you.

Is there an API for the HCIBENCH system? We need to ba able to query it to determine status, which tests are set to run, etc. It would also be great if it could send an email or something when the test completes.

I am having a recurring problem where by the number of VM's reported back after a test is not consistent. I am using the default easy run option (have also found it with other custom runs). It deploys 40 VM's for this test but often only reports around 35 in the results. It's the same with both FIO and VCBench. I also checked that I can ping all 40 VM's from the HCIBench VM during the test run. The logs state is faults to SSH to the missings VM's. I am trying to compare the impact of encryption on an 8 node stretched cluster. Any advice greatly received! :)

this looks like network issue, or some host was disconnected when the testing was running? Could you help to repro this issue and send all hcibench logs to vsanperformance@vmware.com?

Jun 22, 2020

Thanks, Logs sent! No host network issues or disconnected hosts seen during the tests.
