You don't need to use Gossip to store that,  you can just put it in a table.

Thank you so much for answers :)


*What type of info did you wish to pass around?*[image: Images intégrées 1]

In fact, i have on each node a directory ‘MyFiles’ which contains three
files (E.g file1v2.txt, file2v1.txt, file3v4.txt)

I’d like to modify this interface and add another column.

Example:

10.194.171.160

……………..

Rack1

file1v2.txt, file2v1.txt, file3v4.txt





Any help please ?

Re: Gossip Protocol

You can start by using the nodetool gossipinfo command and also look at the
ApplicationState source code:
https://github.com/apache/cassandra/blob/cassandra-3.1.1/src/java/org/apache/cassandra/gms/ApplicationState.java

That application state is not currently user-extensible for Cassandra users.

What type of info did you wish to pass around?

Hello,

To get detailed description/Architecture of Gossip protocol please check the below link :

https://wiki.apache.org/cassandra/ArchitectureGossip

Also you can try nodetool gossipinfo command , output of this will guide you on details saved by gossip.
