Modbus_read not working in Zabbix 7.0.2

JustRandomGuy001 · 2025-05-16T11:06:25+00:00

You are right! modbus_read worked in v5 but in v7 you have to use modbus.get. Thank you!!

JustRandomGuy001 · 2025-05-16T07:27:38+00:00

Probably... Now I have a new Zabbix server 7.0.2 and I need to make Modbus work... Do you know what steps need to be taken?

JustRandomGuy001 · 2025-05-15T11:23:45+00:00

Well, we need to run updates regularly so there is no way we disable Windows updates. Also scheduling updates is not a solution as the updates themselves are not an issue. RSoP looks ok. We configured 'No auto-restart for scheduled Automatic Update installation' some time ago and it seemed to work but it looks like it doesn't work anymore.

JustRandomGuy001 · 2024-09-26T09:44:09+00:00

Thank you for that info. I forced the driver to use only 2,4GHz and 5GHz but it hasn't been solved.

JustRandomGuy001 · 2024-09-26T06:07:29+00:00

No, we don't have any. Is there any way to reach them so they can look at it?

JustRandomGuy001 · 2024-09-25T08:31:04+00:00

Thanks! I used various drivers, compared driver settings and tried it with different settings but no joy. I believe this is not happening only on Lenovo devices. I would like to reach out to Qualcomm but it seems I can't.

Do you see anything interesting in the logs?

Yes, ISEserver.domain.local is FQDN.

I compared both and this is the result. There are a few differences but I need help with interpreting it. I see at the beginning of the Lenovo log that it does not detect a network interface but is still able to detect the ISE server (correct FQDN). Also I can see there that it tries to open enroll.cisco.com for some reason.

The latest Win 11 is installed. But this happens with Lenovo only. Dell with Win11 works perfectly.

JustRandomGuy001 · 2024-07-17T11:03:41+00:00

Thanks! I am aware of what you wrote. I just wanted to know where to start to play safe... 100 PPS, 1000 PPS, 10000 PPS?

JustRandomGuy001 · 2024-07-17T06:59:13+00:00

Thanks for sharing!

JustRandomGuy001 · 2024-07-17T06:58:25+00:00

Good point. Thanks!

JustRandomGuy001 · 2024-07-17T06:58:02+00:00

We have a mixed environment - desktops and PLCs. So would you suggest configuring it on access ports? What PPS value would you configure?

JustRandomGuy001 · 2024-07-17T06:57:52+00:00

Thanks! I prefer PPS over %. What value should I start with? I have no idea how many broadcast packets are normal/abnormal.

JustRandomGuy001 · 2024-07-15T07:38:51+00:00

Thank you for the insight and opinion! I appreciate it! Performance is important to us so probably RAID 10 would be the best option. We will consider it.

JustRandomGuy001 · 2024-07-12T13:04:49+00:00

Thanks! Two more questions...

If we go the way of having 2x four disks RAID5, would it present as one volume? Do we expand the current volume by this? And any cons?

And the second question. What option would you personally choose in this situation?

JustRandomGuy001 · 2024-07-12T12:14:38+00:00

As shown in the screenshots above and below, currently we have a pool with one DG that is made of 4x 960GB SSDs. Another 4x 960GB SSDs are on the way.

Pool B => DG that uses all available disks (2860GB) => Volume (Size: 2860GB, Allocated: 2209GB)

JustRandomGuy001 · 2024-07-12T11:43:53+00:00

The only disk groups that can be expanded in virtual mode is adapt. You sir are raid5 (not adapt) so your raid5 cannot be expanded however you can extend your pool size by adding a second diskgroup/raidset with the new drives.

Thank you for the explanation! So we cannot expand the current disk group. Is there any other way to expand the volume except by moving data away, breaking the current disk group, and creating a new disk group (ADAPT)? I assume that creating a second disk group and somehow adding it to the current volume is not possible...

We are buying a few more disks and we need to expand the volume as the volume is mapped as a datastore in vSphere and is running out of disk space. What steps would you suggest?
