Hi, Im a bit confuse with the redis server as a broker. Im planning to setup a production architecture to centralised all the logs of different application of 3000 server on ELK but something is confusing me. Here is my configs : 3 nodes elasticsearch 1.7x (ES cluster) 2 node logstash indexer 1.5 (multiple ES node output for on each LS nodes| serve as load balanced if I or remove a node) logstash-forwarded on each servers 1000 servers will be using one LS node and 2000 servers will use the second LS node. Does logstash-forwarder have a buffer if I lose connection between the server and the LS indexer ? If I setup a redis server will I be able to use logstash forwarded ? Does how much can logstash hold if I lose connection between LS and ES nodes ? ---

> Does logstash-forwarder have a buffer if I lose connection between the server and the LS indexer ? The files themselves act as a buffer. LSF will simply stop reading from them. > If I setup a redis server will I be able to use logstash forwarded ? Yes, but you need a Logstash instance to receive the messages from LSF and submit them to Redis. > Does how much can logstash hold if I lose connection between LS and ES nodes ? Logstash itself has no internal queue so messages will queue up in Redis. ---
