The following steps will run a small NSQ cluster on your local machine and walk through publishing, consuming, and archiving messages to disk. follow the instructions in the INSTALLING doc. in one shell, start nsqlookupd: $ nsqlookupd in another shell, start nsqd: $ nsqd --lookupd-tcp-address= in another shell, start nsqadmin: $ nsqadmin --lookupd-http-address= publish an initial message (creates the topic in the cluster, too): $ curl -d 'hello world 1' 'http://127.0.0.1:4151/put?topic=test' finally, in another shell, start nsq_to_file: $ nsq_to_file --topic=test --output-dir=/tmp --lookupd-http-address= publish more messages to nsqd: $ curl -d 'hello world 2' 'http://127.0.0.1:4151/put?topic=test' $ curl -d 'hello world 3' 'http://127.0.0.1:4151/put?topic=test' to verify things worked as expected, in a web browser open http://127.0.0.1:4171/ to view the nsqadmin UI and see statistics. Also, check the contents of the log files (test.*.log) written to /tmp. The important lesson here is that nsq_to_file (the client) is not explicitly told where the test topic is produced, it retrieves this information from nsqlookupd and, despite the timing of the connection, no messages are lost.
