Visualizzare i client connessi in Redis

Redis ha determinati strumenti per visualizzare informazioni sui client connessi.

Oggi vediamo come visualizzare quelli connessi, con diversi campi; la descrizine la potete vedere qua sotto (ripresa dalla documentazione ufficiale):

    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
