ASPNET Alert for ApplicationRestarts Monitor

I created following monitors and assigned them to a node.

1) ApplicationRestarts using "WMI Performance Counter Monitor" component type.

2) ASPNET Process that monitors w3wp.exe process using "Process Monitor - WMI" component type. (Never mind the thresholds on this)

Next I want to setup an alert with following condition:

If process with name "w3wp.exe" experiences application restarts > 10, then I want to be notified.

To set this condition, I went into "Solarwinds Orion/System Manager", clicked on "Configure Advanced Alerts" in Alerts menu. Clicked on New which brought me into Edit Advanced Alert dialog box. Clicked on "Trigger Condition" table and chose "APM: Condition" for Type of Property to Monitor. Then created following conditions:

1) ComponentName is equal to ApplicationRestarts

2) Process (Service) Name is equal to w3wp.exe

The only thing lacking is to inject the condition (ApplicationRestarts > 10) into the above mix.

Just don't know how to set this condition. If I am going the wrong way to set the alert based on my condition, please let me know.

Any help is appreciated.

Thanks.

Hi,

The only thing lacking is to inject the condition (ApplicationRestarts > 10) into the above mix.

Neither Orion or nor APM know this variable.

An advanced alert configured through the wizard will not let you compute a such value based on NPM events.

A solution would be to setup a Windows Script monitor that checks the start events for that process on the remote server. The script can then compute how many restarts ocurred during e.g. the past hour, then set the component as down, otherwise let it to up.

Once your new component is setup and assuming it sits in the same template as your "Process Monitor - WMI" one, setup the alert to trigger when the application is down.

You can use the default "Alert me when an application goes down" adv. alert if you do not want to bother too much creating a new alert.

Let me know if you need any details.

HTH,

Thanks for reply. How do I report "Down" and "Up" from the script?

The status is set through the exit code of a script.

0-Up | 1-Down | 2-Warning | 3-Critical | Any other value - Unknown

I attached a script that does nearly what you need. It searches for a specific event (that you need to modify, WMI Explorer is handful for that) and then compare it with the last value returned stored in a text file (that you have to create and set to 0 to initialize the script). If the new value is superior to the previous value returned, it sets the monitor as down. So if you modify the script to count the number of events for the past hour or so, you can return one of the above status definition.

Use that script at your own risks .

Figured out from help doco. Included below for others:

Visual Basic Scripts Report Status Through Exit Codes

Scripts must report their status by exiting with the appropriate exit code:

Exit Code Meaning
0 Up
1 Down
2 Warning
3 Critical
Any other value Unknown
