Cluster node performance (storage, heap and CPU)

Is your feature request related to a problem? Please describe.

Deployment administrators need to know how their Elasticsearch cluster is doing, performance wise. For each cluster node, HW wise, there are 3 parameters that matter:

• JVM memory pressure (heap)
• CPU usage
• Storage allocation

And we need to find a visual way to represent that.

Right now, we show the last 2 parameters in cloud, under the Instances section of a deployment. The layout isn't very visual and it's overwhelming the user with information that isn't necessary or useful, until you have a problem with the node.

Describe the solution you'd like

We'd need a 3 parameter component per node, that shows heap, CPU usage and storage. A cluster can have between 1 node and tens of nodes, so it needs to scale well.

Ideally, the node viz should also be able to show the overall health of each node, which can be:

• healthy
• stopped routing requests
• unhealthy

High CPU usage does not make a node unhealthy, nor does high JVM memory pressure.

Each parameter should be actionable.

I'd like to give users the filters for:

• node types
• node health
• deciding which parameters they want to see.

I'm not married to this idea and am very open to different explorations 🙂

Closing this because it's not planned to be resolved in the foreseeable future. It will be tracked in our Icebox and will be re-opened if our priorities change. Feel free to re-open if you think it should be melted sooner.
