In addition to using traditional extension attributes to store endoint information in Jamf Pro, we store some useful information locally on each client. This "reverse extension attribute" data is stored in what we call a "host info" file. There are more than a dozen pieces of data in our host info file that are used for a variety of tasks. This video will explore setting up a host info file and a few different methods of populating the data, including API queries, script output and timestamps. You will also learn how to use the host file in conjunction with Jamf Pro policies and notifications to execute a robust macOS patching system on a fleet of Macs.
