Raspberry PI - Temperature, Voltage , Freq

cweakland · 11 July 2017 15:44

Just to recap, I only see graphs for codecs, no voltage graphs are displaing. Here is the discovery output requested: https://pastebin.com/L5qzmm3D

Thanks again!

I tried reverting back to the commit mentioned in some previous post. LibreNMS looked different back then. All sensors were removed from the device on discovery, so I reverted back. Now I have two CPU temp for one of the pi’s

Jo0Lz · 14 July 2017 11:03

Any ideas? I’ve messed up the sensors on one of the pi’s, it now has two temperature sensors, both with the same data… Re-discovery doesn’t seem to resolve it.

@mirino75 @mwen Is your libreNMS install still showing correct values/sensors?

I’ve tried reverting back, but I think the build is too old, maybe you guys can point us in the right direction?

So, a new patch is live, and after changing raspberry.sh like mentioned in the patch, I see new sensors.
However, on both installs, it’s reporting back 0 as value.

Same boat here, updated the script and I get all zeros. Here is the output of my snmp walk, is the output of the snmpwalk correct, should it be one long quoted string like this? I noticed in the past each sensor got its own OID string (like a tree), sorry I am not an expert in snmp verbage. Any how hope it helps, Thanks again for all the help on this!

We need:

./discovery.php -h HOSTNAME -d -m sensors
./poller.php -h HOSTNAME -d -m sensors -r -f

No love, here is a new round of output:

I reverted the patch and changed the snmp extend script, still no luck. Also just so you know, though all of this I have always got the temperature reading in my graphs.

Here is the latest output:
discovery: https://pastebin.com/jbJWvtaH
poller: https://pastebin.com/qH0TYyXk

arrmo · 5 August 2017 17:50

Yep, same here … temperature is working, but the rest are broken now. FYI, this used to work on my machine.

Thanks!

laf · 5 August 2017 21:32

No just the snmp extend script that needs reverting to the one I linked to. You should be running latest master for LibreNMS core.

arrmo · 5 August 2017 21:48

Yep, running the latest LibreNMS core (updated this morning, just to make sure). And the extend script … you mean raspberry.sh, that is called from snmpd on the client (RPi), right? That’s what I updated.

cweakland · 6 August 2017 15:29

Sorry about that, I just re-applied the patch, and reverted to the older snmp extend script. No luck

If someone wants to provide:

./discovery.php -h HOSTNAME -d | ./pbin.sh
./poller.php -h HOSTNAME -r -f -d | ./pbin.sh
snmpbulkwalk -OUneb -v2c -c COMMUNITY HOSTNAME .  | ./pbin.sh

Then we can take more of a look.

cweakland · 6 August 2017 19:22

Here ya go, this is inclusive of the changes requested above (patch and reverted snmpd script).

Reverted raspberry.sh to the one you linked and am running the latest master without any patches.

@cweakland you made a typo in the first command

The host is not found

Fixed in: https://github.com/librenms/librenms/pull/7131

Will merge once checks are done.
