根因分析

某个命令的执行时间超过了延迟监控阈值,表明操作缓慢或系统过载。

English

A command execution time exceeded the latency-monitor-threshold, indicating a slow operation or system overload.

解决方案

  1. 使用 SLOWLOG GET 识别慢命令并优化(例如减小键大小、使用管道或拆分大操作)。
  2. 运行:redis-cli --latency 检查网络延迟;如果高,将 Redis 移动到更靠近客户端的位置或使用更快的网络。

无效尝试

常见但无效的做法:

  1. Increase latency-monitor-threshold to a very high value 40% 失败

    Masking the symptom without addressing root cause (e.g., slow commands, large keys, or network issues).

  2. Disable latency monitoring entirely with CONFIG SET latency-monitor-threshold 0 30% 失败

    Removes visibility into performance issues, making debugging harder later.
