The OS Cluster Layer
This layer will appear only if the target Linux servers are in a high availability cluster setup. With the help of the tests mapped to this layer, you can determine the following:
- Know which nodes are part of a cluster;
- Determine the current state of each node;
- Determine the current state of each daemon;
- Track the current capacity and usage of cluster resources and proactively detect potential space crunches.
