A introduction to using system tools to identify what the system is doing. This will go over using top and iostat to determine what the system is physically doing, and then using tools like ps and querying the PostgreSQL system catalog tables to determine what queries are running, what locks have been acquired, and where the tables and indexes are physically located on the system in order to correlate the physical activity to what the database is doing.
