      Description

      There have been a bunch of NodeManager health checker improvement requests in the past.

      Right now, I expect that initially there just need to be a bunch of base functionality added. The most obvious parts are:

      • Finding appropriate measurements of health
      • Storing measurements as metrics. This should allow easy comparison of good nodes and bad nodes. This should eventually lead to threshold blacklisting/whitelisting.
      • Adding metrics to the NodeManager UI

      After this basic functionality is added, we can start consider some enhanced form of NodeManager health status conditions.
