Workflow Execution Context

Workflows execute asynchronously in the Oracle ZFS Storage Appliance shell, running (by default) as the user executing the workflow. As such, workflows have at their disposal the Oracle ZFS Storage Appliance scripting facility, and may interact with the Oracle ZFS Storgae Appliance just as any other instance of the Oracle ZFS Storage Appliance shell. That is, workflows may execute commands, parse output, modify state, and so on. Here is a more complicated example that uses the run function to return the current CPU utilization:

var workflow = {
       name: 'CPU utilization',
       description: 'Displays the current CPU utilization',
       execute: function () {
               run('analytics datasets select name=cpu.utilization');
               cpu = run('csv 1').split('\n')[1].split(',');
               return ('At ' + cpu[0] + ', utilization is ' + cpu[1] + '%');
       }
};
