This is the third in a series of articles giving extended example of how to use the RestAPI. This article will demonstrate how to generate a report equivalent to the Version 3 "OutputUsers" view using PowerShell.

You can download the latest version of the file: OutputUsers.ps1, and simply customise the $user, $pass and $sonar values and it should run in your environment

Build the CSV file header row

PowerShell has a number of built in libraries for handling output to various file formats. For this example we will be saving the results in a CSV file that can be viewed directly in EXCEL or imported into other databases.

# Since we always insert all the columns in the same order, we don't need to insert the code to force an ordering here unless you NEED the empty columns
$csv | Export-csv OutputUsers.csv -NoTypeInformation		# We will further refine this line later

As this report has a smaller number of columns and requires simpler logic, that's all we need to do.

What might be useful to add?

This script duplicates the output from the Version 3 report as closely as possible. 
It might be useful to include the device hostname ($currApp.devices[0].host_name) or the application name (usually Instance name for MS SQL or database name for Oracle for example, found in $currApp.name) as columns in the spreadsheet.
