Metrics
Redis is an in-memory data structure store known for its speed and flexibility. Monitoring its metrics is essential to maintain performance, stability, and reliability. The following is a list of key Redis metrics in PDS. Understanding these metrics will help administrators optimize performance, troubleshoot issues, and ensure the Redis instance runs smoothly.
