Airfiber Radio RX Level

blue-yu · 5 February 2017 19:18

Hello,

I just switched from observium, and noticed that librenms is not showing Radio RX Level from my Airfibers. In observium I had those. Any idea?

That info should be available as far as I know. Do you have the wifi modules enabled for the device? If so please pastebin the output of ./poller.php -h HOSTNAME -r -f -d -m wifi

Hi again,

Any idea why RX Level is missing?

BR…

laf · 12 February 2017 22:34

Can you be more specific, I see a lot of RX data in that output

blue-yu · 13 February 2017 07:15

Lets put it simple: There is no “Receive power” aka “radio_rx_level”

RX Chain 0: .3.6.1.4.1.41112.1.3.2.1.11.1
RX Chain 1: .3.6.1.4.1.41112.1.3.2.1.14.1
Remote RX Chain 0: .3.6.1.4.1.41112.1.3.2.1.19.1
Remote RX Chain 1: .3.6.1.4.1.41112.1.3.2.1.22.1

laf · 13 February 2017 09:42

What’s the OID name for those values?

blue-yu · 13 February 2017 10:08

iso.org.dod.internet.private.enterprises.ubnt.ubntMIB.ubntAirFIBER.airFiberStatus.airFiberStatusEntry.rxPower0.1

I hope that this is what You are asking.

barryodonovan · 14 February 2017 10:21

I have added the local Rx and will create a PR now.

In order to get the graphs to work though it is necessary to add a DS to the RRD.
This can be done easily by deleting the existing RRD and allowing librenms to recreate it but you will lose historical data (you could try merging old and new using an rrdmerge tool but YMMV)
Alternatively if you are running rrd > 1.5.0 you can use ‘rrdtune’ to add DS:

rrdtool tune PATH-TO-RRD/RRD-FILENAME.RRD DS:rxPower0:GAUGE:600:U:100000000000 DS:rxPower1:GAUGE:600:U:100000000000 RRA:AVERAGE:0.5:1:2016 RRA:AVERAGE:0.5:6:1440 RRA:AVERAGE:0.5:24:1440 RRA:AVERAGE:0.5:288:1440 RRA:MIN:0.5:1:720 RRA:MIN:0.5:6:1440 RRA:MIN:0.5:24:775 RRA:MIN:0.5:288:797 RRA:MAX:0.5:1:720 RRA:MAX:0.5:6:1440 RRA:MAX:0.5:24:775 RRA:MAX:0.5:288:797 RRA:LAST:0.5:1:1440

blue-yu · 14 February 2017 11:27

Uff, I have no idea what did You told me Newbie here DS? RRD? YMMV?

It’s all Greek to me (Španska sela - ko me razume)…

florianbeer · 14 February 2017 15:45

RRD is the tool that’s used to store data and draw graphs, DS simply refers to a “data source”. You can read more about it here: https://oss.oetiker.ch/rrdtool/tut/rrd-beginners.en.html

YMMV is “internet slang” and means: your mileage may vary; http://dictionary.cambridge.org/dictionary/english/ymmv

blue-yu · 14 February 2017 17:35

Hello,

I don’t need data for now. I am only testing librenms for now. So, if I delete my airfiber, and add it again, I should get additional data?

blue-yu · 15 February 2017 18:43

Please help. New install of librenms is also not giving me RX Levels for Airfiber. What should I do?

blue-yu · 6 April 2017 05:31

Hi,

RX level finally works, but there is something wrong with the graphs. Can someone take a look at it?

barryodonovan · 11 April 2017 16:36

Hmmm, thought mine were ok but…

barryodonovan · 11 April 2017 16:50

I’ve just added a pull request removing the rrd graph options which cause this issue.
Old graph:

New graph:

blue-yu · 12 April 2017 16:34

Hi,

How can I get these new graphs?

BR…

laf · 13 April 2017 09:13

Update your install

blue-yu · 13 April 2017 09:26

Oh Yes. It’s working now. Thanks a lot…
