TABLE 18–9 HTTP Service Statistics (Developer Profile)
Statistic Units Data Type Comments
bytesreceived Bytes CountStatistic The cumulative value of the bytes
received by each of the request
processors.
bytessent Bytes CountStatistic The cumulative value of the bytes sent by
each of the request processors.
currentthreadcount Number CountStatistic The number of processing threads
currently in the listener thread pool.
currentthreadsbusy Number CountStatistic The number of request processing
threads currently in use in the listener
thread pool serving requests.
errorcount Number CountStatistic The cumulative value of the error count,
which represents the number of cases
where the response code is greater than or
equal to 400.
maxsparethreads Number CountStatistic The maximum number of unused
response processing threads that can
exist.
minsparethreads Number CountStatistic The minimum number of unused
response processing threads that can
exist.
maxthreads Number CountStatistic The maximum number of request
processing threads created by the listener.
maxtime Milliseconds CountStatistic The maximum amount of time for
processing threads.
processing-time Milliseconds CountStatistic 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.
request-count Number CountStatistic The total number of requests processed so
far.
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.
