Getting a list of healthy/unhealthy clusters

[PieterBoeren]

Is it possible to get a list of healthy and unhealthy clusters? I'm adding health checks to my clusters, but I would love to have some way to get which clusters are healthy (or even better, how many destinations of that cluster are healthy) and which not.

I basically want to build a dashboard to show the current status of the API's, but as far as I can tell, there is no easy way to get the status of the clusters.

We've explored similar ideas (#123) but haven't tried building this out yet. In theory you can build this today. Note clusters are not marked healthy or unhealthy, only destinations have heath state.

• Implement IClusterChangeListener and add it as a singleton in the DI container. This will let you collect the cluster instances as they're added to the system.
• In your health dashboard you check each cluster
  • Check each destination in ClusterState.Destinations.
    • Check DestinationState.Health.

Let us know how that works for you.

Yes, this does work. An event or something would be easier, but this will suffice. Thanks for the pointers.

Discovered a bug though: #1134
