Description
Plotting cr.node.liveness.heartbeatfailures as a custom metric graph works if we're plotting the count, but not if we're plotting a rate. If the heartbeat failures are rare, this means we're looking for a +1 increase in a mostly flat graph (instead of looking for a spike), which isn't very effective.
