Monitor server-side latency for Amazon MemoryDB for Valkey
Database Blog
The article discusses monitoring server-side latency for Amazon MemoryDB for Valkey, a high-performance in-memory database service.
- New CloudWatch metrics introduced: SuccessfulReadRequestLatency and SuccessfulWriteRequestLatency
- Metrics measure server response time in microseconds for successfully executed requests
- Key areas to investigate for high latency include:
- Long-running commands
- Request queueing time
- Data persistence time
- Memory utilization
- Data tiering performance
- Recommended monitoring approaches:
- Monitor p50 latency for typical use cases
- Use p99 or p99.99 for latency-sensitive applications
The goal is to help users detect, diagnose, and maintain healthy MemoryDB for Valkey clusters by understanding and monitoring server-side latency.
