The Performance Data Collection Engine (PDCE) processes performance data collected by BDL scripts. Performance data collected with such scripts can be displayed in Performance Explorer in real-time. Entities collected by the PDCE are called measures, which may be specified in BDL using the following functions:
These functions are called within transactions. One-to-many measures are allowed within each transaction. Furthermore, monitoring projects can use exactly one script defining exactly one usergroup. This usergroup may define one init transaction, one end transaction and one main transaction.
Wrapper functions, defined in bdlMonitor.bdh, are used to deliver additional functionality that is necessary for BDL realtime monitoring. See the Supplemental tutorials for information on using these functions:
