Hello,

I am a R&D engineer in Grid'5000 and I am currently working on 
developing a network monitoring platform for it.
I am interested in integrating CoMo in the current platform.

For doing this I need your help in the following matters:

Documentation
I already read it on the mailing list, but I coming back with the 
question, is there any documentation on how to write a new module?
At the lab we are using a specific hardware device for packet capturing 
called GNET (_http://www.gtrc.aist.go.jp/gnet_ ), in order to integrate 
it with CoMo I need to write a driver for it, is there any documentation 
on how to do this?

Storage
Also, is it possible to filter the packets from a capture and store the 
filtered capture in another file?
If I enable CoMo to permanently capture packets from sFlow and NetFlow 
on 10Gb links, for how long the packets are stored? and the analysis?

Queries
Is it possible to split a capture file (pcap file) in flows and then 
make other analysis on this flows?
Is it possible to make modules that computes the distribution of some 
metrics like flow size distribution, packet size distribution?
Is it possible to integrate the output of the queries with RRD?
I am for sure missing something, but how can I save the output of a 
query into a file?
If I am having a pcap trace file, on which I enabled the traffic module, 
how can i get the evolution of the traffic in time, not just the final 
results?

Performance
Is it able to capture and analyze packet from 10Gb links without loss?

Misc
Are there any other types of documentation that will help me in 
understanding how the system is build beside the articles on the CoMo page?
Is it possible to define a query priority that stops all the other queries?
Does comolive work with the last version from svn of como? I am getting 
the following error:
"Fatal error: Call to undefined function: file_put_contents() in 
/var/www/comolive/config/index.php on line 228"


Thank you very much,
