Extend Windows OS - Servers Pattern

Govindarajan · ‎07-14-2020

hi i need aolution for the below task in discovery stimulator

As the Cloud Dimensions Discovery Administrator, you are tasked with extending the Windows OS - Servers pattern, using your knowledge and skills. Some guidance is provided below:

Using IP 198.51.100.176, extend the Windows OS - Servers pattern as follows:
Create a pattern extension called Custom Steps

Step 1 called Time Zone
Operation WMI Query
Namespace = "\root\CIMV2"
Tables and Fields: Use this website to determine the correct Table and Field entries
https://docs.microsoft.com/en-us/windows/win32/cimwin32prov/win32-timezone

Step 2 called Trim Time Zone
Operation = Parse Variable
Use https://regex101.com/ for parsing strategy assistance
Run Discovery against 198.51.100.176 and verify the Time Zone field is populated .

thanks,

These steps were able to successfully validate Task 09.

Open the 'Windows OS - Servers' pattern

Select New in the Extension Section

Set the Name to 'Custom Steps'

Setup the WMI Query. I only chose to pull back the caption value for simplicity sake.

Now add another Step called Trim Time Zone to parse the variable. Since the lab calls for regex, you'll really want to use regex101 to play with the expression to whatever you feel comfortable. There are literally at three different ways off the top of my head to parse the output. I used one I new would work for any of the outputs in case there were different time zones.

Since we're extending the pattern, there is a lot of other classes being discovered at the same time. If you look at the CI Attributes section you can see them. So if you tried to just insert the variable u_time_time the step is going to fail. So make sure your variables include the table (class) you're going to push this to.

For the Regular Expression I just chose:

[A-Z]{3}

which in a nutshell is grab find the first three occurrences of capital letters.

Save the Pattern

Goto MidServers and Sync Patterns ( I honestly don't think this is required but I have made this a habit when I do any pattern work so I don't think about it).

Run Discovery against the Server requested. I tested first with the mid-server as a sanity check and then did the other.

And..

Success validation.

Note; if you hit submit, your instance will immediate be deactivated, though you can reenroll at any point and I would highly recommend just thinking up weird things to discover and work through adding them in. This is definitely a once you know it you suddenly start doing it a lot in your real-world environments.

Hope this helps and good luck!

Hi Steele, On the second step, can you explain the pre condition? **If $timeZone[2].Caption isEmpty** Why is there a number 2 in the bracket instead of an asterix (*) Also shouldn't the condition be "isNotEmpty" instead of "isEmpty"? Appreciate your time.
