Edge Data Streaming Node Restart and Failover

To maximize operation time in the event of a failure, the EDS Node can restart on the same machine or fail over to a backup machine.
The EDS Node process script node.sh runs the processmonitor-node.sh script which detects if the EDS Node is running. If the EDS Node process stops unexpectedly, the processmonitor-node.sh script restarts the EDS Node.
The ./remote-node.sh script detects if a EDS Node that is installed on a remote machine is running. If the remote EDS Node stops unexpectedly, the ./remote-node.sh script restarts it.
When a EDS Node process fails, it fails over to one of the backup machines which share the EDS Node name. The EDS Node on the active machine starts collecting data from the data source.
