Get client’s full last command (including key) from Redis

Question

Redis’s client list will give you the last command issued by client. It does not give you the key that last command was issued on. What I would like to get is the list key a client is doing BLPOP on.

Is there a way to get this?

Although it would be nice to have that kind introspective functionality, it does not exist in Redis ATM. Instead you can try catching the command in-flight to understand what your client is doing.

The straightforward manner to do that is running MONITOR (from a different connection) before the client issues the BLPOP command to get that information. Note that MONITOR carries a performance impact so you should refrain from doing it in production.

I was afraid of that. Thank you for your response! I'm also considering adding pub/sub message along side of the push command to bettering logging/monitoring. – Jeremiah Oct 05 '15 at 00:22
What if the command you want to inspect is an administrative command? – Jasper-M Dec 03 '21 at 11:19
MONITOR also reports about admin commands (with passwords redacted, mostly) – Itamar Haber Dec 04 '21 at 13:34
