When i use One single Datasource for Multiple servers it then displays all the Raw Data on any of the server from Datasource. Can I force it to display only specific Data point outputs on the RawDat tab. Thank you Please ask me if you need more elaboration.

Can you post the details of the DataSource you've built? I assume this is still to do with the powershell based datasource?

Thank you Yes this a powershell based Datasource. For example : My "AppliesTo" picks 3 servers from the pool. So now this Datasource is common to the three servers. 3 Data points are built into the Datasource. Problem: While viewing each Server individually from "Resources"..... I can see Raw Data for all three servers. Question : Can I make this Data point specific. I mean if I navigate to Server1, I should only see Raw Data for Server 1. Thank you, Please questions if scenario isn't clear.

Ok, what are the three datapoints for? The number of datapoints should represent the number of datapoints you'd see on one server. So, if you are collecting CPU %, Memory %, and Swap %, you'd have 9 datapoints (3 servers x 3 datapoints). If you have three datapoints, one for each server, what you really want is one datapoint. What does the "collector" field look like? Does it say script or batchscript? What does your script output look like?

My powershell script in the datasource box is like below Invoke command - computername Server1 - scriptblock { Logic to Size of folder = x } Invoke command - computername Server2 - scriptblock { Logic to Size of folder = y } Invoke command - computername Server3 - scriptblock { Logic to Size of folder = z } So each script output is like eg: X= 20 Data points collecting key value pairs Datapoint1 =x..... Datapoint2=y and Datapoint3=z My Requirement : Server1 should display only Datapoint1 Raw data and not other 2 data. Anything you could help or point me to? Thank you

Ok, cool. What you need to do is adjust your script so that it talks to only one server and outputs only one datapoint. Instead of manually specifying server1, server2, and server3 in your script, you would bring the server name in as a variable. How you do this depends on a few things. Is this a multi-instance datasource? If so, are you in script or batchscript mode? If it's a single instance datasource, you'll be using script mode, so the collector will run your script once for each server. To get the hostname into a variable in your powershell script like this: $hostname = '##SYSTEM.HOSTNAME##'; Then your invoke command would only happen once and would look like this: Invoke command - computername $hostname - scriptblock { Logic to Size of folder = x } So, each execution of the script would output metrics for that one server. The number of metrics for one server would be the same number of datapoints defined.

Hey Stuart

After spending some time on it i managed to get some sample scripts and understood exactly what it does and how.



## Active Script ##

                $hostname = '##SYSTEM.HOSTNAME##'

                $namespace = "root\cimv2"

                $query = "SELECT NAME FROM Win32_LogicalDisk"

                                $output = Get-WmiObject -Namespace $namespace -ComputerName $hostname -Query $query

                                foreach ($instance in $output) {

                                    $name = $instance.Name

                    Write-Host "$name##$name"

                }

                exit





## Collector Script ##

$hostname = '##SYSTEM.HOSTNAME##'

$wildvalue = '##WILDVALUE##'

$namespace = "root\cimv2"

$query = "SELECT * FROM Win32_LogicalDisk WHERE NAME='$wildvalue'"

$output = Get-WmiObject -Namespace $namespace -ComputerName $hostname -Query $query

Write-Host "Size=$($output.Size)"

Write-Host "FreeSpace=$($output.FreeSpace)"

exit

Now i remain with few other questions

1. This is WMI so gets me the partition names, how can i get the paths to iterate in Active script

So I manually Added monitored instances under my resource, but didn't work for me.

2. Tried Setting up UNC.PATH, didn't work

I'll spend time trying few things here n there until I hear back from you.

Please advice

Thank you

If you have an active discovery script, you won't need to manually add instances. If you want to discover different instances, like folders instead of partition names, you'll need to adjust your query. You might consider pulling from the Win32_Directory class instead of the Win32_LogicalDisk class.

Not sure what you tried to setup here.

From the looks of your script, you could probably do this without a script by using the built in WMI collector. To help you get started, this is how you would set it up to pull free space on each logical drive. I did this so you can compare it to what you already have in your script. To make it for folders, like I said above, you'd need to use the Win32_Directory class instead. I'm not familiar with that class, so you'd have to do a little research.
