Product Operations Status Summary Metrics

The Product Operations Status Summary Metrics (POSSUM) computer program provides a readable view into the state of the Phoenix Operations Product Generation Subsystem (OPGS) data pipeline. POSSUM provides a user interface that can search the data store, collect product metadata, and display the results in an easily-readable layout. It was designed with flexibility in mind for support in future missions. Flexibility over various data store hierarchies is provided through the disk-searching facilities of Marsviewer. This is a proven program that has been in operational use since the first day of the Phoenix mission.

POSSUM presents a graphical representation for tracking and accountability of the existence and version of expected Reduced Data Records (RDRs) for a given Experiment Data Record (EDR) for the Phoenix lander mission. By using POSSUM, operations personnel can easily determine if any RDRs are missing for a given EDR during and after OPGS processing pipeline. A variety of sort options exists, including product file creation time and instrument.
