[genofire]

should we fetch the nodeID here, of the gateway?

like in output/meshviewer-ffrgb:

yanic/output/meshviewer-ffrgb/struct.go

Line 153 in dfd456b

node.GatewayIPv4 = nodes.GetNodeIDbyAddress(statistic.GatewayIPv4)

[maurerle]

we would then have to "nodes" somehow to influx output - do you know how to manage this?

In the current way, I do not see the gateway set as a tag.. I don't know what i am doing wrong :D

[genofire]

you are correct, that it needs a refactory to get nodes ...

to manage it, i need to look and test myself ... first tought, do we have something equal for links already.

i believe nothing, could it be, that you mixup influxdb and influxdb2 ?

[maurerle]

I confirm this works, can be merged :)

[maurerle]

I had something wrong with my install, now it worked..
I mean we could just remove the ':' in the string - as this is likely the nodeid? But I don't know if you can rely on that.

Having it as a nodeid would be much better, as we do not have the mac anywhere else..
