SERT / Re: SERT 2.0.6,2.0.7
« Last post by Mr.Brown on September 28, 2023, 07:39:20 AM »
Hi pgalizia,

sorry for the delay in this case.
I resolved both issues i had with the following solutions:

1. for the LU Worklet i tested all range numbers from 1-10 and in my case with number 2 the error message were gone.
2. i managed to clear this issue with the "Range Discovery" Test after that a "Full Test" was okay with no error.

Thank you for the help and for the recommendations.

Kind Regards
Mr. Brown

Hi Tien,

PTDaemon LXI support works well on Ubuntu 18-20. Later Ubuntu versions have a change in their RPC interface that breaks the third-party LXI code. I assume that same change affects RHEL as well, so older RHEL versions may also work.

Hello, when I try running the following command
./ptd-linux-x86 -L 49 x.x.x.x

It gave me the following error on RHEL 9.2 OS

How can I connect to a Yokogawa WT310e on RHEL 9.2 Linux? What Linux OS should I use?

Thank you, Mr.Brown, for the logs.  Those are quite helpful!

From what I see, it looks like there are two issues:
  • The LU worklet's transactions are at 90.2% of the target
  • The power sensor has 100% of its samples with unknown certainty

For the LU worklet, I see "cpuWarmupIntervalCount" in "config-all.xml" is set to "8" (instead of the default of 3).  You may need to experiment with values between 3 and 10 to find the right number of warmups for the LU worklet (I've seen cases where setting cpuWarmupIntervalCount too high resulted in a similar issue for LU, and once I reduced it one or two iterations, it was fine).

As for the power sensor running with unknown certainty, this could be caused running the sensor with auto-ranging on. which isn't supported for SERT runs (doesn't allow for uncertainty measurements).  See Section 5 in, which describes how to set up SERT's power ranges.  You can also check the "Power and Temperature Measurement Setup Guide" at for additional information that may be relevant to your Hioki PW3337 device.

Give those items a try and let me know if that resolves those problems.  Thanks again!

Hi pgalizia,

my first issue is resolved, seems like pending Windows Updates with integrated Driver Updates were the Problem for that. Now the Test is starting and running till the end.

But i have a new Problem, i have some error messages in my results, see the attached screenshot ( new issue ), furthermore i created the log files for that new issue.

Kind Regards

Hello Mr.Brown,

Could you generate some log files using the collector scripts and attach those, so we can get a better look at what's going on with that setup?

See, Section 7.1.  That explains how to setup the log file collection, start the SERT run, and then find the resulting log files afterward.  That should give us a better idea of what the problem might be.

SERT / SERT 2.0.6,2.0.7
« Last post by Mr.Brown on September 12, 2023, 02:46:16 AM »

currently i have some Problems with the SERT ( 2.0.6, 2.0.7 ) after quite some time I wanted to Test some more Systems.

First I had some Problems, with the Connection to the Host Disk Drives which I managed to fix, but now there is another Problem occurred.

When I start the Test a message with “attempting to start test suit” appears , see screenshot1.

After about 3-4 minutes the Test finishes, which is quite strange, see screenshot2.

When I look into the Results, I see that the workloads are configured but no results has been recorded for them, see screenshot3.

Hope you can help me with this Problem.

Kind regards

Sorry for the late reply. I will confirm the above 6 points.

Best regards,

No problem!

I know from other benchmarks that it doesn't take many changes to SSD configurations to cause a change in performance.  Some things you can check:
  • Did just the drive capacity change?
  • If this is a different drive, how do the hardware specifications compare to the original drive?  Different PCIe generations can and will perform differently, for example, or there could be a difference in firmware, even with the same manufacturer.
  • Was the original drive well-conditioned, and the new drive fairly unused?  There's good literature online about conditioning SSD drives so they give consistent results when benchmarking (as opposed to a brand-new drive that can give wildly-different results until conditioning is achieved).
  • Was the new drive placed in the exact same bay -- for example -- as the original?  Some systems do have different performance numbers based on what PCIe slot/bay is used for the drive.
  • Did the number of drives change?  Adding or removing the number of drives and their types will cause score changes.
  • And of course, were write caches disabled on the new drive?

Excuse me for continuing.

I changed the SSD capacity from 480GB to 240GB and the storage score changed significantly from about 60 to 300.

Other configurations were not changed. Is it possible to fluctuate so greatly?
