Method Detail

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 -

executionTime -

Whenever statement leak happens, increment numPotentialStatementLeak count.

Parameters:

poolName - JdbcConnectionPool that has got a statement leak event.
