Action tab has different Action cycles that will run automatically as per schedule mentioned in SCCM server.
- Application Deployment Evaluation Cycle: This cycle will check new application deployment polices available to client computer & start installation as per schedule.
- Data Discovery Collection Cycle: It generates a new discovery data record (DDR). When the DDR is processed by the site server, Discovery Data Manager adds or updates resource information from the DDR in the site database.
- File Collection Cycle: When a file is specified for collection, the Microsoft System Center Configuration Manager software inventory agent searches for that file when it runs a software inventory scan on each client in the site. If the software inventory client agent finds a file that should be collected, the file is attached to the inventory file and sent to the site server. This action differs from software inventory in that it actually sends the file to the site server, so that it can be later viewed using Resource Explorer. This is a part of SCCM inventory functionality.
- Hardware Inventory Cycle: Collects information such as available disk space, processor type, and operating system about each computer. This is a part of SCCM inventory functionality.
- Machine Policy Retrieval & Evaluation Cycle: The client downloads its policy on a schedule. By default, this value is configured to every 60 minutes and is configured with the option Policy polling interval (minutes).
- Software Inventory Cycle: Collects software inventory data directly from files (such as .exe files) by inventorying the file header information. SCCM can also inventory unknown files — files that do not have detailed information in their file headers. This provides a flexible, easy-to-maintain software inventory method. Software inventory and collected file information for a client can be viewed using Resource Explorer. This is a part of SCCM inventory functionality.
- Software Metering Usage Report Cycle: collects the data that allows you to monitor and client software usage.
- User Policy Retrieval & Evaluation Cycle: Similar to Machine Policy Retrieval & Evaluation Cycle, it will initiate user policies.
- Windows Installer Source List update Cycle: causes the Product Source Update Manager to complete a full update cycle. When you install an application using Windows Installer, those Windows Installer applications try to return to the path they were installed from when they need to install new components, repair the application, or update the application. This location is called the Windows Installer source location. Windows Installer Source Location Manager can automatically search SCCM distribution points for the source files, even if the application was not originally installed from a distribution point.
