You can configure how much data should be retained for DTP projects. Data Collector regularly prunes the database to reduce the amount of disk space DTP uses. You can change the global default settings by modifying the DCConfig.xml file located in the <DTP_DATA_DIR>/grs/config directory. See Configuring Data Collector for additional details.
- Choose Report Center Settings from the settings (gear icon) menu.
- Choose Projects in the Administration sidebar and click on the project you want to configure.
- Change the value for each data type in the Build Details Settings section. The value indicates the number of builds-worth of data to retain.
