Performance data is collected in units called records. By using APIs, you can obtain necessary information in such record units.
Records are categorized into two types depending on their features.
- Records starting with PD are of the PD (product detail) record type. PD-type records collect performance data, information indicating the system status at a certain time (such as detailed information about processes that are currently running). You can use PD-type records to identify the status of the system at a certain time.
- Records starting with PI are of the PI (product interval) record type. PI-type records collect performance data over a fixed interval, such as the number of processes that are running per minute. You can use PI-type records to analyze the changes or trends in the system status over time.
