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.
