    Description

      We do not have good data on the effectiveness of the LNet health resend feature. I propose that we instrument the code to track completed and expired resends, so we could see how many times we actually complete a network transaction via retry mechanism vs. how many times the transaction fails despite resends. This data can then be used to improve the feature.
