RedisMetricredis.net.output
Total bytes written to network
Summary
Total bytes sent by Redis over network connections since startup. The rate indicates outbound network throughput, typically dominated by query responses and replication data to replicas. High output rates may indicate large response payloads, inefficient queries returning excessive data, or heavy replication traffic. Monitor alongside client output buffer memory to detect slow consumers causing buffer accumulation.

When Redis disconnects slow clients that can't keep up with output buffer, redis.clients.connected drops suddenly. This is often caused by clients with slow network connections or blocking on their end, especially for pub/sub subscribers or replicas.
When redis.replication.repl_backlog_size is too small relative to write rate and network latency, replicas require full resync after brief disconnections, causing replication storms and increased master load.
