Redis Client Connect Test





CLIENT LIST

The CLIENT LIST command returns information and statistics about the client connections server in a mostly human readable format.

Return value

Bulk string reply: a unique string, formatted as follows:

  • One client connection per line (separated by LF)
  • Each line is composed of a succession of property=value fields separated by a space character.

Here is the meaning of the fields:

  • id: an unique 64-bit client ID (introduced in Redis 2.8.12).
  • addr: address/port of the client
  • fd: file descriptor corresponding to the socket
  • age: total duration of the connection in seconds
  • idle: idle time of the connection in seconds
  • flags: client flags (see below)
  • db: current database ID
  • sub: number of channel subscriptions
  • psub: number of pattern matching subscriptions
  • multi: number of commands in a MULTI/EXEC context
  • qbuf: query buffer length (0 means no query pending)
  • qbuf-free: free space of the query buffer (0 means the buffer is full)
  • obl: output buffer length
  • oll: output list length (replies are queued in this list when the buffer is full)
  • omem: output buffer memory usage
  • events: file descriptor events (see below)
  • cmd: last command played

The client flags can be a combination of:

O: the client is a slave in MONITOR mode
S: the client is a normal slave server
M: the client is a master
x: the client is in a MULTI/EXEC context
b: the client is waiting in a blocking operation
i: the client is waiting for a VM I/O (deprecated)
d: a watched keys has been modified - EXEC will fail
c: connection to be closed after writing entire reply
u: the client is unblocked
U: the client is connected via a Unix domain socket
r: the client is in readonly mode against a cluster node
A: connection to be closed ASAP
N: no specific flag set

The file descriptor events can be:

r: the client socket is readable (event loop)
w: the client socket is writable (event loop)
