"errorTrace": ""

Answer 1

Question with full details :-

I have scom2019. Whenever I run the rest api http://<scomhost>/OperationsManager/data/alert from powershell script on the same scom host then I am getting the result.

But when I invoke the http://<scomhost>/OperationsManager/data/alert api by passing the authentication from postman I always get the following error
{
"errorMessage": "Your session with the Web console server expired.",
"errorTrace": ""
}

Am I missing something? Do I need to pass any headers or paramaters or do I need to enable something on scom side to make the rest api work from some other host?

Can you please help to resolve the issue.

Hi @mahesh palem ,

I don't know how to use Postman, but to retrieve alert data you will need to specify some criteria as you can see in my PowerShell example over here:

Which SCOM version and build are you running? There is a fix in Update Rollup 1 for SCOM 2019 that fixes an issue with the “Your session with the Web Console server expired."
