[Sensors] OMV-Sensors in OMV 4.1.x

sbocquet · Mar 7th 2018

Hi,

After several years, I'm back here OMV have really upgraded since I left and I'm please to see that. For several personal reasons (kids ) I left the project at some time, but I will have more time to come as the kids grows up !
Anyway, I'm planning to move my actual NAS witch is running on a Windows Server 2012 Essential (fine but getting old...) to OMV

I'm trying to do everything I was doing with it with OMV and I'm near the goal, except to with the ability to watch for my CPU & HDD temp.

I have seen some posts in the forums but cannot find the answer for OMV 4.x.

Is the plugin OMV-sensors available as I cannot see it in the plugins with OMV-extras installed?
I'm actually running with a backport 4.14 kernel.

Thanks for the answer,

The plugin is not in the OMV 4.x repo but the 3.x plugin might work. @jhmiller should be able to answer that and put it in the 4.x repo if it does work.

Hi Aaron

Thanks for your answer and the next question is :

how can I install an OMV v3 plugin in OMV v4 ?

Download .deb file and install it the hard way (dpkg -i ...) ?

Cheers,

Download it from here. Then you can either upload it to the omv web interface in the plugin tab or use dpkg.

Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no):

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.

Some systems (mainly servers) implement IPMI, a set of common interfaces
through which system health data may be retrieved, amongst other things.
We first try to get the information from SMBIOS. If we don't find it
there, we have to read from arbitrary I/O ports to probe for such
interfaces. This is normally safe. Do you want to scan for IPMI
interfaces? (YES/no): 
Probing for `IPMI BMC KCS' at 0xca0...                      No
Probing for `IPMI BMC SMIC' at 0xca8...                     No


Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (YES/no): 
Probing for `National Semiconductor LM78' at 0x290...       No
Probing for `National Semiconductor LM79' at 0x290...       No
Probing for `Winbond W83781D' at 0x290...                   No
Probing for `Winbond W83782D' at 0x290...                   No


Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no): 
Sorry, no supported PCI bus adapters found.
Module i2c-dev loaded successfully.


Sorry, no sensors were detected.
Either your system has no sensors, or they are not supported, or
they are connected to an I2C or SMBus adapter that is not
supported. If you find out what chips are on your board, check
http://www.lm-sensors.org/wiki/Devices for driver status.

As I'm testing all my stuff in a VM, I'm not surprise by the no sensors detected, but it seems to install correctly...

I have some Python error at the end, but I have read that it should be resolved sooner or later ?

sbocquet · Mar 7th 2018

Ok... got errors but the answer was post several times... If someone could delete post 6 to 10 !!!

When I try to activate the plugin, I have this error. It seems that omv-mkgraph is no more present in v4.x...
Maybe some works to do on the plugin to have it running on OMV v4.

This is a python bug. While there is a fix on the forum, I am waiting for debian to fix it.

It probably still works on systems that have upgraded from 3.x to 4.x because omv-mkgraph is still around. I guess the plugin needs more changes for OMV 4.x. While I use lm-sensors, I don't use the graphs in OMV and none of my test OMV boxes are physical.

If you see an error message, it is actually the spam filter putting the post in moderation (long posts and/or links in posts do that). So, no need to re-submit.

I upgraded from OMV 3 to OMV 4. But since the Sensors plugin is not available for OMV 4, I removed it from OMV 3 before upgrading to OMV 4.

The plugin seems to have installed OK on OMV 4, but it bombs later when setting it up because omv-mkgraph is missing.

I understood from a post some time ago that you are running OMV4 on your QNAP TS451. Do you use lm-sensors to manage fan control on that box? How exactly? If not then how is it done?

Thanks

Yep.

Nope. I have lm-sensors installed but I just let the system manage the fan.

sbocquet · Apr 5th 2018

Hi there !

Now that OMV 4 is considered as stable, any chance to have an update to let this plugin run on it ?

Cheers,

sbocquet · Apr 11th 2018

I'l trying to make it work even if the GUI seems broken with the omv-mkgraph command (replaced by omv-mkrrdgraph)

First step -> Catch and generate the datas => done

- apt-get install lm-sensors and run sensor-detect

- added a /etc/collectd/collectd.conf.d/sensors.conf file filled with
LoadPlugin sensors

- added a /etc/collectd/collectd.conf.d/smart.conf file filled with
LoadPlugin smart

- apt-get install libatasmart4 (for sata datas)

- service collectd restart

Now, I need to understand how omv-mkrrdgraph works...

As far as I can see, a conf file is need in /usr/share/openmediavault/mkrrdgraph/plugins.d to generate the .png file displayed in the GUI...

Any help is welcome for those who wants...

Sorry to keep coming back on this one!

OMV4 is running fine on my TS-451 except that the fan runs all the time where it never used to do so using qnap software.

I have installed lm-sensors and fancontrol but I am concluding from "sensors-detect" and "pwmconfig" that there are no pwm-capable sensor modules installed.

Does that sound right to you?
What does the output of "sensors" look like on your machine?
Does your fan also run 24/7?
What have you got in your lm-sensors config file?
In what way does the "system manage the fan"?

Thanks for your help.

N

EDIT - Please ignore these questions. The problem was that SmartFan was enabled in BIOS which somehow hides the fan from lm-sensors. With SmartFan disabled in BIOS all works as expected.

David B · May 12th 2018

I use the OMV-Senors plugin on my server. I wonder if this plugin is the reason the collectd-core configuration keeps failing when I test upgrades. I guess there's only one way to find out!

Edit: That seems to be it! Uninstalling the OMV Sensors plugin seems to have solved the problem.

sbocquet · May 12th 2018

Yes. The plugin need to be upgraded.

I managed to get it work the hard way, without the plugin. The dark side is that I must redo the changes at each OMV update. I saved those and just copy back the conf files.

Could you post your changes? If you post what you did, I MAY be able to figure out what to do to the plugin code to make it work.

sbocquet · May 12th 2018

First, you need to collect the datas => see post 12

Second, you need to generate the graphs with omv-mkrrdgraph

Third, run omv-mkrrdgraph and check the new generated PNG file in /var/lib/openmediavault/rrd/*.png (download it to your pc or else)

That's a simple example. After that, you can do more, like add a tab to have your disks temp, or have multiple graph/page with modifying the WebGUI of OMV (see attached files).

Feel free to ask your questions if needed.

If you're willing to give it a try, here's an experimental build of the plugin for OMV 4.

Hi,

I tried the plugin, but it does not seem to work as smoothly as usually expected for OMV.
Is there any further instruction or troubleshooting needed?
I need to say, that on my machine lm-sensors is already giving correct results, but without a way to put it into a GUI.

Thanks for the effort!

Yeah I noticed that after releasing the build I posted. The graph doesn't update. I will see what I can do about that.
