Web Application Availability Monitor

Larry_Grant

I am working on setting up a Web Application Availability Monitor for a specific website on a few servers. I am attempting to configure the monitor to alert on anything other than status code 200. When I run the test on the monitor from scom I am getting a 401 error.

When I run the powershell   $statuscode = (Invoke-WebRequest -Timeoutsec 3 -UseDefaultCredentials -Uri http://url).StatusCode Write-Host $statuscode it returns a code 200

Any thoughts on what I am missing?

Review you SCOM service account permisisons on the web app. The 401 returns as unauthorized where I guess the powershell are running under your user credentials.

I logged into the scom server as the run as account and ran the powershell script as the runas account and it returned the status code 200.

I also added an external resource (microsoft.com) and that returns a status code 200 from the Web Application Availability Monitor

That sounds like the monitor is configured for anonymous connections, that you need to configure it to connect via the service account.

When I switch to Web Application Transaction Monitoring type and set up the test to specify creds I get the below error...

Note: The following information was gathered when the operation was attempted. The information may appear cryptic but provides context for the error. The application will continue to run.

Interesting development on this issue.. I switch the monitor to using a proxy of an internal URL using port 80 and now I get a status code of 200.... even with the server off....
