Understanding Workflows
A workflow is embodied in a valid ECMAscript file, containing a single global variable,
workflow. This is an Object that must contain at least three members:
TABLE 125
Required member
name

execute
EXAMPLE 18
The following is an example of a basic workflow:
var workflow = {
};
Uploading this workflow will result in a new workflow named "Hello world"; executing the
workflow will result in the output "hello world!"
EXAMPLE 19
Workflows execute asynchronously in the appliance shell, running (by default) as the user
executing the workflow. As such, workflows have at their disposal the appliance scripting
facility (see
as any other instance of the 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 = {
};
