SNMP configuration about addon-nut HOT 15 CLOSED

👋 Thanks for opening your first issue here! If you're reporting a 🐛 bug, please make sure you include steps to reproduce it. Also, logs, error messages and information about your hardware might be useful.

from addon-nut.

As I'm sure you can appreciate, we can't test and validate every UPS config out there. Although in theory it should work from what I can see, is there a chance you could validate using SNMP v1/2 rather than V3?

from addon-nut.

Yep, I and understand not having the ability to test all configurations. I just wanted to check if you might know how SNMP can be configured. I also tried v1 with the same result. I also set logging to debug level and other then giving me some debug statements on Pwned database calls, it did not provide any additional information as to why snmp-ups is failing.

Is there any way to send/add "-DD" argument to snmp-ups executable to show detailed debug info? E.g., snmp-ups -DD

SNMP v1 config:

devices:
  - name: apcups
    driver: snmp-ups
    port: 172.20.0.55
    config:
      community: public
      snmp_version: v1
      mibs: apcc
      pollfreq: 15

from addon-nut.

To get the addon to start, you can set the config to be something like:

devices:
  - name: myups
    driver: dummy-ups
    port: dummy.dev
    config: []

This would start using the dummy driver, you could then possibly exec into the container and run the nut executables from there.

from addon-nut.

Does the plugin create the ups.conf file similar to below and run the below command? I'll give the dummy command a shot.

The contents of the ups.conf file

[APC_UPS]
                   driver = snmp-ups
                   port = 172.20.0.55
                   snmp_version = v3
                   secLevel = authPriv
                   secName = snmpprofile1
                   authPassword = *********
                   authProtocol = MD5
                   privPassword = *********
                   privProtocol = DES
                   desc = "APC UPS"

Command:
$ sudo /lib/nut/snmp-ups -DD -a APC_UPS

from addon-nut.

We generate the ups.conf

Only run the -D on debug being set today, we could change this if needed:

from addon-nut.

I was able to exec into the container.... Editing the /etc/nut/ups.conf and running /usr/lib/nut/snmp-ups -DD -a myups worked fine.

Looks like the config param values are not getting set.

This is what I have in the config (for devices):

devices:
  - name: myups
    driver: dummy-ups
    port: dummy.dev
    config: []
  - name: apcups
    driver: snmp-ups
    port: 172.20.0.55
    config:
      snmp_version: v3
      secLevel: authPriv
      secName: snmpprofile1
      authPassword: myauthenticationpassphrase
      authProtocol: MD5
      privPassword: myprivatepassphrase
      privProtocol: DES
      desc: APC UPS

And here is what is in the /etc/nut/ups.conf file:

from addon-nut.

@kkellner Try an array of strings for the config option, like so:

Documentation for config option: https://github.com/hassio-addons/addon-nut/blob/master/README.md#sub-option-config

devices:
  - name: myups
    driver: dummy-ups
    port: dummy.dev
    config: []
  - name: apcups
    driver: snmp-ups
    port: 172.20.0.55
    config:
      - snmp_version = v3
      - secLevel = authPriv
      - secName = snmpprofile1
      - authPassword = myauthenticationpassphrase
      - authProtocol = MD5
      - privPassword = myprivatepassphrase
      - privProtocol = DES
      - desc = APC UPS

I believe I originally set it up this way due to validation restraints when using nested arrays in add-on config files.

from addon-nut.

So when I type this config section in the plugin config text box:

    config:
      snmp_version = v3
      secLevel = authPriv
      secName = snmpprofile1
      authPassword = myauthenticationpassphrase
      authProtocol = MD5
      privPassword = myprivatepassphrase
      privProtocol = DES
      desc = APC UPS

then click save, it turns to this in the config text box:

    config: >-
      snmp_version = v3 secLevel = authPriv secName = snmpprofile1 authPassword
      = myauthenticationpassphrase authProtocol = MD5 privPassword =
      myprivatepassphrase privProtocol = DES desc = APC UPS

The ups.conf ends up looking like this:

Please review my sample config again carefully. The hyphens at the beginning of each line are required.

from addon-nut.

Sorry, too many cut/paste/edits. Your version with hyphens worked. I'm going to add the sensor next to see if I have real data.

from addon-nut.

That is great news! Please report back your findings so that we can close this issue if nothing further needs to be implemented to get this to work without in-container modifications.

from addon-nut.

Looks like I've getting real data! Two questions:

1. Where does host a0d7b954-nut come from and when might it change? I saw in another issue the statement this will change if the addon moves from the edge repo. but I don't know what that means.

2. Is there a way to get additional attributes? E.g., current in voltage and out voltage, ups temperature?

from addon-nut.

Awesome, even more great news!

1. The host is derived from the name of the container, which I believe is generated based on the hash of the add-on repo and the name of the add-on. In this case a0d7b954 is the repo hash (Community Edge repo) and nut is the add-on slug.

2. In a normal install, the available sensors are specific to each model of UPS device and what it exposes. I am not 100% sure on how to expose that same data via SNMP, as I have never before used SNMP.
