It's well known that we are able to calculate redis hit-rate by using redis-cli info command(to check key_hits and key_misses).

However, these two metrics record only hits&misses in query cases(i.e., GET command) . Are there any ways to solve my problem (recoding the successful rate of all executed DEL commands)?

  • As we all know, when deleting a key, it will return either 1 or 0, meaning success(hit) and failure(miss) respectively. These would not affect the acquired metrics we obtain by `redis-cli info` command. – jaki Jul 30 '18 at 12:36
  • it seems you can only get the number of successful delete operations, but there's no way to get the number of missed delete operations. – for_stack Jul 30 '18 at 16:02
