a pure-php client

[gggeek]

I'd like to build a pure-php implementation of the data-gathering part
of pinba, that will send data to a pinba-engine for collection.
Since I plan to deliver as a plugin to existing php apps that are
deployed on many different customers platforms, using a custom php
extension is a no go - offering a limited subset of the pinba-
extension functionality is an acceptable compromise otoh.

So the questions I have hare:
- did anybody try this before?
- is the net protocol between pinba extension and engine documented
somewhere?

Thanks
Gaetano

Probably not, 'cause I've never heard about it.

Pinba uses Google Protocol Buffers as a protocol.
I can see several GPB implementations in PHP:
https://github.com/drslump/Protobuf-PHP
https://github.com/undr/phpbuf
and there are probably some more.

Look in the extension (or daemon) sources for pinba.proto, that's the proto file you
need to use to be able to 'speak' to Pinba daemon.

Let me know if you need any help, I think such thing could be useful for other people
and I might want to add it to the distribution.

I did a naive implementation of the protocol in node.js for pinba_http, a HTTP to Pinba gateway that ease the tracking of client side events. The code is available on github: https://github.com/rs/pinba_http

Hope it can help you.

As far as I understand, that is used only for serialization of the messages. The network part does not rely on "standard" rpc protocols, correct?

The network part is as simple as that: the serialized message is sent by UDP to the server using sendto().

Ok, so here's an alpha version of the code.
Caveat: it is only minimally tested (I did not even set up a pinba server to check if the messages generated by the code are ok).
The GPB encoding code was taken from the protobuf library, but simplified to reduce bloat and be compatible with older php versions (original code used namespaces).

What about next steps? I can set this up on github as my own project, or it could be incorporated into pinba's main repo...

ps: code is now on github

[gggeek]

pps: the code on github has now seen notable improvements: it is now tested against both pinba and pinba2 servers, and it supporst most of the features of the pinba php extension ver. 1.1.2
