Azure Cache for Redis now offers an additional metric in Azure Monitor to measure the 99th percentile latency of server-side commands. This allows you to see the worst-case latency experienced by your Redis instance, which helps in debugging latency challenges in your application stack. You can also use this metric to help determine when long-running commands are increasing the response latency of your Redis instance. The 99th percentile latency metric is available in the basic, standard, and premium tiers of Azure Cache for Redis.
