Installed HCIBench successfully, not able to see any data in Grafana dashboard. Am I missing any config?

We have this issue sometimes - I find that it is usually browser related and if I use a different browser it works

We are going to need a bit more information.

- The vSAN or FIO/VDBench dashboard (or both)?
- Are you seeing the Grafana page and no data in the dashboard, or the page does not display at all?
- What are the IP subnet used?

I was not able to run a test while putting a host into maintenance mode. Config validation fails with this message: "host xxx is in maintenance mode. Please exit maintenance mode and try again!" If I disregard that warning and proceed to test, the test fails with this:

2021-04-23 03:26:47 +0000: Checking Existing VMs...
2021-04-23 03:26:48 +0000: Deployment Started.
2021-04-23 03:27:03 +0000: [ERROR] VM Deployment Failed...

Is there a reason why we don't allow benchmark test with host in maintenance mode? I am trying to test the "worst-case" scenario performance, for example, when we lose a host in a cluster, due to hardware failure, scheduled maintenance, etc.

Last year we used HCIBench 2.3.1 on our vSAN cluster and now after adding some more hosts we're trying to run it again. Hweever, we have deleted out old VMs and we're not able to get the generated VMs to boot.

The hci-fio-datastore* VMs tries to PXE boot and then comes with the message Operating system not found.

Is there a way to either workaroud this problem in 2.5.3 or to download the old version?

did you get chance to pass the pre-validation?

this could be due to DNS or network issue.

Apr 12, 2021

I have run "validate config", but not pre-validation. Where can I find that option? Anyways.. The two clusters have the very same dns configuration and are connected to the same vCenter, so I'm not sure why the disks of the validation and test VMs are not getting partitioned so as the validation VMs aren't able to boot they will also not suffer from a potential dns problem as they currently are stuck at boot time.

to me it looks like network issue from hcibench to vcenter and/or esxi hosts.
could you run the validation again and send me the logs in /opt/automation/logs to

We also have an old vSAN cluster that is being phased out. It has a lot of Intel hosts with ESXi 6.7U3. VMs are booting perfectly fine on this cluster.

The cluster we're planning to run HCIBench on has AMD EPYC hosts and is running ESXi 7.0U1 build 17551050.

Greetings to all,

We have a problem with HCIBench - or more accurately my companys security scanning software has a problem with it. We are using the latest version and it is running Apache Tomcat Version 8.5.4. However our scanners dont like that and want version (released last year).

My question(s)

Can we update the Apache Version within the appliance? We tried but it failed for reasons that are unclear (I am not a linux specialist!)
Will there be a release of HCIBench soon that will contain Apache Tomcat of later?
How often are new versions released?

Thank you,

Apr 14, 2021

Solution: Firewall was blocking port 443 from generated VMs and HCIBench VM to ESXi hosts.

lemme find a way to help you upgrade Tomcat to And ill put it into next release too, but it would be in another month.

May 19, 2021

Hi Chen - Did you manage to look at this? My security people are chasing me again unfortunately. Will the new release, which I hope is coming real soon, have a later version of Tomcat?


Apr 08, 2021

If you can find a way to upgrade that would be brilliant!
