Chapter 15. The billing Service

dCache has built-in monitoring capabilities which provide an overview of the activity and performance of the installation’s doors and pools. There are two options for how this data can be represented and stored:

  • a set of log files written to a known location
  • a database (the billing database).

These options can be enabled simultaneously. If the database option is selected, the data in those tables will also be displayed as a set of histogram plots on the installation’s web page.
