Query Explanation

The alert triggers when a Redis instance has a configured maxmemory (i.e., redis_memory_max_bytes > 0) and its current memory usage exceeds 90 % of that limit, as indicated by redis_memory_used_bytes / redis_memory_max_bytes * 100 > 90. In other words, the rule fires when used memory is > 90 % of the configured maxmemory for any instance.
