Cluster Check

On a cluster, the cluster check command is available to:

  • Network: test and validate connectivity from each node to every other node, for each port required, as well as the time taken to connect to each node.
    • Checks for access to port 27020 on database hosts is not required from web proxy nodes.
    • Checks for access to port 443 is only required from web proxy nodes to unified nodes.
  • Disk: carry out a drive space percentage check
  • NTP: at NTP is functioning

This command should also be run before carrying out a system upgrade.

Example output (abbreviated):

$ cluster check
