SNMP bandwidth monitor using statistics

Thanks, the derivative method has been giving me more accurate readings. Except every once in a while, it was resulting up with a really large negative numbers (which screws up the graph view). Not sure what’s causing it (possibly my router misreporting…), but added a max function to ignore those results.

I’m wondering if with this data I can create a new template sensor or something like that to view the total traffic by day and month, would be possible?

tom_l · November 4, 2020, 5:03pm

Sure just use the wan in and wan out sensors (not the derivative sensors) in the utility meter.

parautenbach · November 5, 2020, 4:40am

See my post.

Thanks! I tried to to use the utility meter but when I put the sensor on a History Graph Card Configuration I’m getting strange results:

What I did wrong?

tom_l · November 5, 2020, 2:09pm

I cant see your image. The host is blocked here. Just drag your image file into the post on the forum.

EDIT: ok that is because the sensors do not have a unit. You will probably want to change that from bytes to MB anyway. Also you have a few errors in your templates (using the in sensor for the out template).

If you are on version 0.117.x this should work:

Thanks! Now the graph is looking right!

Now I’m going to wait an see how to improve the visualization of this data.

tom_l · November 5, 2020, 3:16pm

I think there is something wrong with your template. There’s no way you are using 6 petabytes (10 to the power of 15) in 20 minutes.

GiB would probably be a better unit for general WAN use anyway (I used MiB as I took the template from my 4G cellular connection). Try this:

      erx_wan_download_gib:
        value_template:  "{{ (states('sensor.erx_wan_in')|float/1000000000)|round(2) }}"
        unit_of_measurement: 'GiB'
        friendly_name: Internet in Dev
    
      erx_wan_upload_gib:
        value_template:  "{{ (states('sensor.erx_wan_out')|float/1000000000)|round(2) }}"
        unit_of_measurement: 'GiB'
        friendly_name: Internet out Dev
  
utility_meter:
  wan_in_monthly:
    source: sensor.erx_wan_download_gib
    cycle: monthly 
    
  wan_in_daily:
    source: sensor.erx_wan_download_gib
    cycle: daily
    
  wan_out_monthly:
    source: sensor.erx_wan_upload_gib
    cycle: monthly 
    
  wan_out_daily:
    source: sensor.erx_wan_upload_gib
    cycle: daily

carmolim · November 5, 2020, 3:23pm

I was selecting the wrong sensors, now I think is right:

tom_l · November 5, 2020, 3:27pm

Much better. If you still want to get rid of those extra zeros the template in my post above will measure in GiB.

tom_l · November 5, 2020, 6:01pm

One minor correction. I got my units back to front. It should be MB or GB, not MiB or GiB.

MiB is a power of 2, MB is a power of 10.

ingvarg · November 9, 2020, 2:51pm

Hi @japie101 I have the same switch and would like to see the trafic on the ports. Where did you find the baseoid addresses for the ports?

firstof9 · November 9, 2020, 4:55pm

Use an SNMP walking tool.
You can also look some up here: oid-info.com

japie101 · November 10, 2020, 9:07am

I used an SNMP discovery tool back then, but not sure which program that was anymore.

For your reference:
I am using port 1 of my US-8-60W.

I found one called snmpB the most useful.

SpikeyGG · November 11, 2020, 8:30pm

This is awesome! Thanks for sharing it, I’ve just implement SNMP on my setup and this gives very accurate results.

twproject · November 18, 2020, 10:47am

hi,
shall you share the lovelace code of this graph?

Tnx

twproject · November 18, 2020, 1:36pm

if someone have the same problem with pppoe interface on a Ubiquiti USG, that change the OID randomly every time it restart, I created an appdaemon app to retrieve the data via SNMP and put on 2 HA entities

You can find at: https://github.com/twproject/homeassistant/tree/main/appdaemon/snmp%20query/hassio_unifi_internet_interface

tom_l · November 18, 2020, 1:54pm

OIDs don’t change. Otherwise people would not be able to do this for their USG: https://www.reddit.com/r/homelab/comments/bepzkk/was_able_to_add_a_usg_bandwidth_monitor_and_some/

twproject · November 18, 2020, 3:25pm

OID change with pppoe virtual interfaces, it’s about 6 month that i change my configuration.yaml config with the new values

On october it was 1.3.6.1.2.1.31.1.1.1.6.5 after few weeks after a pppoe restart 1.3.6.1.2.1.31.1.1.1.6.18, now is 1.3.6.1.2.1.31.1.1.1.6.308

As I said at beginning it happen only at pppoe virtual interfaces, It doesn’t change with physical interfaces
