script a wmi query

[miniseb]

i would like to monitor what is going on in my IIS server in term of memory.

IIS works with different worker process each of them is linked to an application pool. I found on the internet how to query the counter i want with a WMI query.
The problem is that i dont have only one WMI query to get what i want :

            
    select VirtualBytes, PrivateBytes from Win32_PerfFormattedData_PerfProc_Process where IDProcess = XX
        => this query allows to get the virtual bytes and the private bytes
    the problem is i can not identify the process so i need another query to do that
        
    select ProcessId from Win32_Process where commandline like "%myApplicationPoolName%"
        => this query allows to identify the application pool and get the pid
        
As the WMI query does not enable to make a inner join, the only way is to program that in VBScript or in other programming language.
Is it possible with NetXMS launch a script periodically and get the result to trace in a graph ?
or maybe there is a different way to get what i want ?

Hi!

You can define new parameters in agent implemented by external script, and then collect these parameters as usual. You can use any external program as parameter handler, and first line of the command's output will be considered as parameter's value. For example, if you have script myscript.vbs and wish to define new parameter AppUsage, you can add the following line to nxagentd.conf:

ExternalParameter = AppUsage:cscript.exe //B //Nologo myscript.vbs

Restart agent, and you will have new parameter AppUsage available for collection.

I am struggling to make that working:

I created a vbscript :
    Dim test
    test = 10
    WScript.Echo test

I insert the following lines in nxagentd.conf :
ExternalParameter = MyParameter:c:\windows\system32\cscript.exe //B //Nologo "c:\MyScript\myscript.vbs"

In the data collection, a new item is shown named "MyParameter". I select it so i see MyParameter in my data collection. The value of this data collection never updates.
thanks for your help

Hi!

jsut check it on my machine, and it looks like cscript suppresses output of WScript.Echo in batch mode, so agent cannot get the result. Changing

ExternalParameter = MyParameter:c:\windows\system32\cscript.exe //B //Nologo "c:\MyScript\myscript.vbs"

to

ExternalParameter = MyParameter:c:\windows\system32\cscript.exe //Nologo "c:\MyScript\myscript.vbs"

gives correct result for MyParameter.

Best regards,
Victor

I have created a folder on one of my nodes c:\myscripts.  On the node that i want to run this script on I right-clicked and hit edit agent's config.  I added the following line:

ExternalParameter = MyAVCheck:c:\windows\system32\cscript.exe //Nologo "C:\myscripts\avscript.vbs"

I hit save and apply.  Also restarted service on the node I was working with.

I have ran

c:\windows\system32\cscript.exe //Nologo "C:\myscripts\avscript.vbs"

from a command prompt and it returns the correct value.

I then right-click my node and select Data Collection.  Right-click again and select New.  Hit the select button under the Data/Parameter section with NetXMS agent selected in the dropdown box.  I do not see the MyAVCheck.  How do i start collecting the value from this script?

I am using 1.0.10 console and 1.0.10 agent for windows.

List of parameters supported by agent updated during configuration poll. If you wish to see new parameters in the list immediately, you should force configuration poll on the node (by selecting Poll -> Configuration from node's context menu).

I did that.  Checked via the same method posted above and still nothing new shows up.  It should show up under Supported agent parameters as MyAVCheck correct?  If so, then nothing is showing up.  Even allowing some time to pass by.  Do I need to add a subagent or anything along those lines?  Also, the vbs file and the config file was edited on the machine I am monitoring.  Nothing needs to be added to the machine that acts as the server correct?

I figured this out.  I placed the externalparameter line below the *PING line in the config.  Moving it above this line and it works perfectly.

Love this app btw, great work.
