No cluster IP related information is specified when oblogproxy is started may lead to problems.

Question: According to the README file, there was no cluster IP related information is specified when the oblogproxy is started. When there are multiple clusters in the same network segment and the clusters share the same user name and password, it will lead to misunderstanding.

As far as I know, username, password and rsList are only used when oblogclient connects to oblogproxy, so they don't need to be concerned when starting the service.

[MaQianyi]

I mean the communication between the oblogproxy and the observers, not the oblogclient to the oblogproxy.

Does the oblogproxy connect to the observer according to the rsList, username and password passed by the oblogclient?

Yes, so oblogproxy can fetch log from different observer clusters according to the requests of multiple oblogclient instances.

Thanks! One more question, In oblogclient, can we set multiple observers to rsList?

ObReaderConfig config = new ObReaderConfig();
// set root server list in format [ip:rpc_port:sql_port]
config.setRsList("127.0.0.1:2882:2881");

seperated by ';'
ip1:rpc_port1:sql_port1;ip2:rpc_port2:sql_port2

These ip-ports must be the same ob cluster.
