![如何监控 memcached 上的“添加”命令的数量](https://linux22.com/image/770269/%E5%A6%82%E4%BD%95%E7%9B%91%E6%8E%A7%20memcached%20%E4%B8%8A%E7%9A%84%E2%80%9C%E6%B7%BB%E5%8A%A0%E2%80%9D%E5%91%BD%E4%BB%A4%E7%9A%84%E6%95%B0%E9%87%8F.png)
因此 memcached 提供了大量统计数据来跟踪使用情况(命中和未命中)。

此列表中包含有关 get、delete、incr、delete 的统计数据。但是,我的应用程序广泛使用了添加并且当更新失败时,没有任何具体的指标来显示。
我如何检查实际添加了多少以及未添加多少?
请注意,我可以通过应用程序执行此操作 - 通过日志记录等,但我正在寻找一种从 memcached 的监控指标中获取此功能的方法。
这可能吗?
