Is there any way to monitor the connection pool

Question

Is there any way to monitor the connection pool like druid monitor？

Recently, I have encountered several times in the online environment that the sharding proxy database connection is unavailable, which will occur one day to one month after the server is started.

At this time, I try to use Navicat to test the direct connection to MySQL. It can connect, but it can’t connect to sharding proxy.

The log is as follows:

### Error querying database.  Cause: org.springframework.jdbc.CannotGetJdbcConne
ctionException: Failed to obtain JDBC Connection; nested exception is java.sql.S
QLTransientConnectionException: HikariPool-1 - Connection is not available, requ
est timed out after 30001ms.
### The error may exist in com/xxx/dao/XXDao.java (b
est guess)
### The error may involve com.xxx.dao.XXDao.selectXXByID
### The error occurred while executing a query
### Cause: org.springframework.jdbc.CannotGetJdbcConnectionException: Failed to
obtain JDBC Connection; nested exception is java.sql.SQLTransientConnectionExcep
tion: HikariPool-1 - Connection is not available, request timed out after 30001m
s.

I hope there is a way to monitor the status of sharding proxy connection pool. Can you give me some suggestions.

Thanks.
