[GitHub] [apisix] hzbd opened a new issue #4124: request help: how to get current limit count from redis cache?
hzbd opened a new issue #4124:
URL: https://github.com/apache/apisix/issues/4124
### Issue description
> https://github.com/apache/apisix/blob/master/docs/en/latest/plugins/limit-count.md
**1. If I use redis to store limit count cache, how to get the current value of count by admin? Is there an admin api interface to get this or do I need to get it from redis by myself?**
**2. How is the key value naming rule of limit count defined?**

hi @tokers
We want to periodically obtain the current `limit count` remaining amount, which is displayed in dashboard. And plan to use limit count as billing credentials, such as 100,000 calls / month.

Q1: Is this part(part 3) a version attribute? Can you help find out where the key generation rules are in the source code?
Q2: If it is convenient for a third-party program to directly obtain the consumer's latest limit count value in redis, can we remove part3 and only keep the latest version?

hi，@tokers
So can we remove the third part? Only keep the latest version (if possible, how to do it?). The version history of the data does not seem to be used in the future, unless it is used for fault tracking.

Just like what I said above, you can customize the key.
