Wireguard missing statistics

[genofire]

@AiyionPrime maybe you have an fix for it

[AiyionPrime]

@genofire What exactly is missing? Maybe I'm looking in the wrong place.

Upstream statistics is implemented like this: https://github.com/freifunk-gluon/gluon/blob/4684f42173bea54c6626ce16fe14397692047775/package/gluon-mesh-vpn-wireguard/src/respondd.c#L204

And returns the result of the ubus-call a few lines below.

That can be reproduced on the commandline of such a node: ubus call wgpeerselector.wg_mesh status

Which returns something like this:

{
    "peers": {
        "sn03": false,
        "sn02": false,
        "sn01": false,
        "sn10": false,
        "sn04": false,
        "sn09": {
            "established": 232847
        },
        "sn06": false,
        "sn07": false,
        "sn08": false,
        "sn05": false
    }
}

I'm not familiar enough with yanic, but our grafana (which displays yanics collected data) appears to extract connected supernodes just fine:

https://stats.ffh.zone/d/EGysRPsMz/router-fur-meshviewer?orgId=1&var-node=44d1fa59f87c&var-saveinterval=60&var-hostname=aiyion-JT-OR750i&var-model=Joy-IT%20JT-OR750i&var-domain=nordstadt&var-owner=freifunk@aiyionpri.me&var-firmware_release=vH23&var-autoupdater=wireguard&viewPanel=24

May you elaborate what statistics are missing and what command one can use to verify your findings?

[genofire]

Thanks for that response - i believe we have to fix upstream the format first - it should be a consistent dataformat:

• false is an boolean and no object -> an object could be null

in next step we could discusse, how to make the data useable in metrics to a database

[genofire]

Boa, i hate lua: https://github.com/freifunk-gluon/packages/blob/0a334b837f9e4bf6eec7a675c93dbc56c140afb3/net/wgpeerselector/files/usr/bin/wgpeerselector#L326-L328

i make a first suggestion: https://github.com/freifunk-gluon/packages/pull/250

[AiyionPrime]

Can't you marshal an enum in go? Like this is either an object or false? That would at least be what my rust code would do :)

[genofire]

We could Start to Marshall to interface{} (and map[string]interface{}) - but then we have to validate so much values afterward. An consisdent structure would be to prefered way, for performance and developer mistaks

[AiyionPrime]

i make a first suggestion: freifunk-gluon/packages#250

@genofire freifunk-gluon/gluon#250 is merged, where do we go from here?

[genofire]

could anybody send us an result of an gluon-neighbour-info -r statistics -d ::1 -p 1001 on a node with running wgpeerselector?

As test-value it would be nice xD

[AiyionPrime]

This device has wgpeerselector installed: vH24 / gluon-v2021.1-148-g9e3cf00e https://hannover.freifunk.net/karte/#/en/map/44d1fa59f87c

hmm that does not look like that is running on the current version after https://github.com/freifunk-gluon/packages/pull/250 was merged:

  "mesh_vpn": {
    "peers": {
      "sn03": false,
      "sn02": false,
      "sn01": false,
      "sn10": false,
      "sn04": false,
      "sn09": false,
      "sn06": false,
      "sn07": {
        "established": 1412632
      },
      "sn08": false,
      "sn05": false
    }
  },

---

in the past (on fastd?) we got an extra level: https://github.com/FreifunkBremen/yanic/blob/aa9d94f97f81dd8f3a78feadbb9cdf17103005a6/data/statistics.go#L49-L52

if i reconstruct it, the data was something like:

  "mesh_vpn": {
    "groups": {
      "fastd0": {
        "peers": {
          "sn03": null,
          "sn02": null,
          "sn01": null,
          "sn04": {
            "established": 1412632
          }
        }
      }
    }
  },

maybe we should clearify the structure on gluon side - so that it become the same way.

[maurerle]

Is this still an open issue? Yanic works well using wireguard on our domain?

[genofire]

Yes, we do not implement any parsing that values (or storing in database)

[maurerle]

In that case - the requested output of gluon-neighbour-info -r statistics -d ::1 -p 1001 of a node running gluon v2023.1.0 with an active wireguard vpn connection is:
