95th percentile slow log duration

Summary

Measures the 95th percentile execution time of commands recorded in Redis's slow query log, typically in microseconds. This metric identifies the upper bound of slow command latency — commands exceeding this threshold affect only the slowest 5% of operations. Rising values indicate query performance degradation, potentially from expensive O(N) operations like KEYS *, large set operations, or blocking commands. Critical for establishing SLA boundaries and detecting application-layer performance regressions before they impact the majority of users.

Slow Query Backlog Masks Redis Connection Pool Exhaustionwarning

Redis slowlog entries accumulating (redis.slowlog.length rising) can indicate operations blocking on network or disk I/O, exhausting connection pools and causing cascading failures in dependent services even when Redis CPU appears healthy.
