Thank you for opening, I agree @ChrsMark we could do something similar with Pods (an the others). A note on using reflect: I've checked this discussion kubernetes-sigs/kubebuilder#592 and it seems that there are better alternatives: Option 1 (I think this one is preferred, as we probably have this package already): Option 2: Using https://github.com/banzaicloud/k8s-objectmatcher, which doesn't look bad either WDYT? |

isUpdated will be nil for all other resources (Pod, Service...), so this will never be true for them.
Perhaps we should have a default isUpdated function, when the option is not present that does just the old != new check?

https://travis-ci.org/github/elastic/beats/builds/712100705 seems like a flake. |

Failing tests seem unrelated, merging. Thanks for contributing this @vjsamuel ! |

Bug
What does this PR do?
Everytime the kubelet does a check for node health it posts an update to the node status. Each change even if overall status doesnt change then it causes the metricset to restart. This PR adds a watcher option to register a func that checks in detail if the update is valid or not.
Why is it important?
This makes sure that the kubelet status updates dont prompt a restart unless the overall status changes.
