Flow designer- how to calculate total disk space on a server?

[Damhoej]

I am trying to figure out how I can create an action in flow designer that wil get me the total disk space on a server.

example:

The server has 3 disks that have different sizes (100, 200 and 300 Gb) that totales to 600 Gb.

I would like to sum these values when different servers have different number of disks?

When I get the total I can use this value further down my flow.

Any suggestions?

When you upgrade to Quebec you'll have "flow variables" that you can use for this purpose.

There's a couple of workarounds you can use in Paris, but none of them are great. You can use the inline scripting to calculate it later when you need it.

I have now upgraded my personal instance to quebec, but I have an issue with my solution.
How do I get the variable to be the sum of "lookup records"? 

I guess I need some sort of adding all the sizes found in the lookup action, it doesn't work if I use "sum" in transformation 😉 
Somehow I need to build the array or do the math for each step.
 
This is how I imagine a flow for calculating disk space on a server:

Edit: forgive the typo of "totalDiskpace"... I only realised I'd missed the s after I'd done the screenshots :-). 

Size is actually a string field that's calculated on save, you'll want to do something like this to add up the bytes: 

And then you can use that value with the OOB script include that the size field uses, like this: 

Which returns: 

In this example I had two storage devices, one with 20 million bytes, and another with 50 million.

One way you can do this is by creating a custom action to be used in your flow. 

Based on your use case:

1. Create 3 action inputs, disk1, disk2, and disk3
2. Create a script step
3. Configure it like this:

24. Here's the script for reference:

a

(function execute(inputs, outputs) {
var num1 = parseInt(inputs.disk1);
var num2 = parseInt(inputs.disk2);
var num3 = parseInt(inputs.disk3);
var sum = num1+num2+num3;

outputs.totaldisk = sum;
})(inputs, outputs);

45. Create an output that takes the sum from the script step

56. You can then use the output to use in your flow to update a field.

57. Remember that you're passing the variable of disk 1 size, disk 2 size and disk 3 size from your initial flow to the inputs you've created.

Hope this solves your issue.
