      • statementCacheHitEvent

        public void statementCacheHitEvent​(String poolName,
                                   String appName,
                                   String moduleName)
        Whenever statement cache is hit, increment numStatementCacheHit count.
        Parameters:
        poolName - JdbcConnectionPool that has got a statement cache hit event.

      • statementCacheMissEvent

        public void statementCacheMissEvent​(String poolName,
                                    String appName,
                                    String moduleName)
        Whenever statement cache miss happens, increment numStatementCacheMiss count.
        Parameters:
        poolName - JdbcConnectionPool that has got a statement cache miss event.

      • traceSQLEvent

        public void traceSQLEvent​(String poolName,
                          String appName,
                          String moduleName,
                          String sql,
                          long executionTime)
        Whenever a sql statement that is traced is to be cache for monitoring purpose, the SQLTrace object is created for the specified sql and updated in the SQLTraceCache. This is used to update the frequently used and slowest sql queries.
        Parameters:
        poolName -
        appName -
        sql -
        moduleName -
