nsqlookupd

nsqlookupd is the daemon that manages topology information. Clients query nsqlookupd to lookup nsqd locations for a specific topic, and nsqd broadcasts topic and channel information.

There are two interfaces: A TCP interface which is used by nsqd for broadcasts, and a HTTP interface for clients to perform discovery.

The HTTP interface has the following API endpoints

• /lookup?topic=....
• /topics
• /delete_channel?topic=...&channel=...
• /ping (returns "OK" for use with monitoring)
• /info returns server version information.
