JDBC Connection Pools Statistics
Monitor JDBC resources to measure performance and capture resource usage at runtime. As
the creation of JDBC connections are expensive and frequently cause performance bottlenecks
in applications, it is crucial to monitor how a JDBC connection pool is releasing and creating
new connections and how many threads are waiting to retrieve a connection from a particular
pool.

Comments
The cumulative value of the bytes
received by each of the request
processors.
The cumulative value of the bytes sent by
each of the request processors.
The number of processing threads
currently in the listener thread pool.
The number of request processing
threads currently in use in the listener
thread pool serving requests.
The cumulative value of the error count,
which represents the number of cases
where the response code is greater than or
equal to 400.
The maximum number of unused
response processing threads that can
exist.
The minimum number of unused
response processing threads that can
exist.
The maximum number of request
processing threads created by the listener.
The maximum amount of time for
processing threads.
The cumulative value of the times taken
to process each request. The processing
time is the average of request processing
times divided by the request count.
The total number of requests processed so
far.
