Redis [QUESTION]how to understand client_total_sent_bytes_outstanding paramter in the output of info command?

when we run the info command and we see there was a parameter named client_total_sent_bytes_outstanding in the Clients section like this:

Clients connected_clients:5 client_longest_output_list:0 client_biggest_input_buf:0 client_total_writes_outstanding:0 client_total_sent_bytes_outstanding:0 blocked_clients:0

but we can't search for the meaning of this parameter on the internet, could you tell me how to understand it?

thanks, advanced.

What version of redis are you running? The latest code doesn't have the field: https://github.com/redis/redis/blob/unstable/src/server.c#L4382

hi, Madolson,

Thanks for your information, we are using Azure Redis, it seems that this parameter may be created by the Azure side?

the Redis version:4.0.14

Yeah, seems to be an azure thing, I would follow up with them about what it means. It's probably client output buffer related, which is the bytes that have been written to client buffers but have yet to be sent out to the wire. But I don't know exactly.
