Feature: add rpc methods with parameters

[fnurglewitz]

Hi, would it be possible to add rpc methods which need parameters?

Adding methods without parameters is quite easy but I'm not sure how I should proceed (I suppose some changes on the binrpc library are needed)

Hello!

Could you give me an example of RPC method with parameters so I can make some tests?

Best

hello, here's an example:

mod.stats core shm

Thank you

Below case is in particular useful where you can scrape any specific (group) statistics listed in kamcmd stats. For example:
kamcmd stats.get_statistics <statistics_name>
kamcmd stats.get_statistics <group:>

Hello guys,

The binrpc package can already handle this, command args need to be appended to the WritePacket function.

Like this:

cookie, err := binrpc.WritePacket(conn, "stats.fetch", "current_opened_connections")

Implementing this in the exporter would be trivial, we could split a command by " "(space) in the fetchBINRPC function.

However, it would be interesting to have a more dynamic list of commands I think. Or maybe we just need to implement stats.fetch all that is available since Kamailio 5.X.
