[collectd] [PATCH 0/2] Ceph collectd plugin

[Yves Mettier]

Hello,

I'm not talking about ceph (Sage will answer to that), but because some 
code was taken from my plugin, let's talk about json implemtations in 
collectd.

https://github.com/collectd/collectd/pull/154 implements a jsonrpc 
plugin (if you know unixsocks, it does the same more or less with 
jsonrpc protocol).

When I developped it, I tried to do it with yajl. Then, I rewrote it 
with libjson. The bad news is that I don't remember why I *needed* to 
quit yajl. I only remember that the move from yajl to libjson was easy.

While reading my code (jsonrpc plugin), I think the 2 reasons why I 
moved to libjson are

1/ yajl is stream oriented and libjson is object oriented. I needed an 
object model and it was easier to use the libjson object model than 
reimplementing it into yajl (what I had begun to do without success).
Note : I may have missed this : 
http://lloyd.github.com/yajl/yajl-2.0.1/yajl__tree_8h.html

2/ yajl has no API to create a tree and generate json from it. Or I 
have missed it.
Would this be easy to implement in yajl ?



Note : it seems there are more than one libjson. The one I'm talking 
about is https://github.com/json-c/json-c/wiki.

Regards,
Yves
