Performance measurement mechanism

A method comprising:

• maintaining a plurality of active database connections to an on-demand database system at a database connection pool, the database connection pool including a plurality of application servers configured to provide access to the on-demand database system by a plurality of clients, the plurality of application servers sharing the plurality of active database connections;
• identifying a plurality of events occurring in the database connection pool;
• generating a plurality of categorization information corresponding with the plurality of events, a designated one of the categorization information including contextual information identifying a designated one of the clients associated with an event;
• determining if a database connection pool exhaustion is indicated based on a first threshold that is based on pool utilization,
• categorizing the database connection pool exhaustion that is indicated in a particular exhaustion condition from a plurality of possible database connection pool conditions based on a second threshold that is based on a number of times the database connection pool experienced the database connection pool exhaustion;
• upon categorizing the database connection pool exhaustion in the particular exhaustion condition, determine if a specific client in the plurality of clients is appropriate to throttle to reduce a likelihood of a connection exhaustion event;
• and
• throttling access to the on-demand database system to the identified client by withholding at least a portion of the active database connections based on the categorization information.
