redis.persistence.aof_current_size

AOF current file size
Dimensions:None
Available on:DatadogDatadog (1)Native (1)PrometheusPrometheus (1)

Summary

Current size in bytes of the append-only file (AOF). AOF size grows continuously as Redis logs every write operation. Large AOF files increase startup time and memory usage during rewrites. Monitor size growth rate to predict when rewrites will trigger (based on auto-aof-rewrite-percentage). Unexpected rapid growth may indicate write-heavy workload changes or rewrite failures.

AOF Persistence Latency from Synchronous Disk Writeswarning

When AOF persistence is enabled with appendfsync always or everysec, slow disk I/O can cause write latency spikes. redis.persistence.aof_last_rewrite_time_sec increasing significantly indicates AOF file growth without rewrite, amplifying disk I/O overhead.
