gluon-emitter

The supernodes must be in the graph somehow.

I would consider an alias file a "dirty hack". I would prefer an announced agent for supernodes. But I will see if an alias file could be an intermediate solution.

I already read your forum posts about that. I basically agree with you, but I need the aliases, because I don't have access to the supernodes of our domain and those who do don't have the time to care about such 'unneccecary' things as announced.

As a middle ground I started to implement the gluon-emitter (https://github.com/ffdo/node-informant/tree/supernode). A small daemon which runs on the supernodes, can read in an alias file, but has also builtin support to dynamically collect different metrics. This WIP. Advantage of this approach is, that it is more suited to automated deployment scenarios like Ansible, Chef etc. and that I don't have to modify anything in the gluon-collector.

Great! I'll start testing it on my computer.

Whoa, sorry wrong impression. I started to implement this, but it is far from finished. Currently I have trouble receiving in the multicast group. Once this is solved we can start testing.

In the supernode branch should now be a first usable version of the gluon-emitter.

We should either rename this issue to "gluon-emitter" (is that possible?) or create a new one and close this one

root@gl1 /o/node-informant# bin/gluon-emitter -interface bat0 -alias alias.yaml 
INFO[0000] Loading alias file                           
FATA[0000] Can't load alias file                         error=Unknown file format .yaml path=alias.yaml

Currently the extension of the alias file needs to be yml or json. A better handling of file types will come soon.

okay maybe that with 'yml instead of 'yaml' should be documented..
It has been running for 10 mins now, but the node is not showing up on the map.

If you have enabled debug output you should see if gluon-emitter is receiving any requests at all and with how many bytes it es responding. Keep in mind that this far from being finished or stable.

It would be nice if gluon-ermitter automaticly pushes the MAC Addresses of all Interfaces on the Server. Here we have different MACs for every interface. Its hard to put them all in a Aliases file because they are dynamic.

@stebifan As you can see in the README automatic collection of facts/statistics is already on the ToDo list.
