Abstract
A method includes collecting trace data associated with a first device tester. A tester health metric is generated for the first device tester. At least one device tested by the first device tester is retested responsive to determining the tester health metric violates a predetermined threshold. A system includes a first device tester operable to test devices and a tester monitoring unit. The tester monitoring unit is operable to collect trace data associated with the first device tester, generate a tester health metric for the first device tester, and initiate a retest of at least one device tested by the first device tester responsive to determining the tester health metric violates a predetermined threshold.
