This API call returns a JSON item made up of numerous vital fields that explain the status of your cluster. Here's an instance reaction.
CPU utilization on your own nodes: It can be practical to visualise CPU use in a very heatmap (like the one particular proven previously mentioned) for each of one's node styles. For example, you could potentially build 3 unique graphs to symbolize Every team of nodes in the cluster (info nodes, primary-suitable nodes, and customer nodes, by way of example) to view if 1 variety of node is being overloaded with exercise in comparison to another.
