I'm not seeing any logs in the AZMSOperationalLogs table in Log Analytics, even though diagnostic settings are enabled for the Service Bus with all log categories selected. I can also confirm that there has been activity on the Service Bus topics and subscriptions, including message sends and receives.

Thank you for reaching out.
If you're checking for logs right after enabling diagnostic settings, please note that it can take up to 90 minutes for logs to start appearing in Log Analytics. Also, the required tables (like AZMSOperationalLogs) are only created after the first logs are received.
That said, if it's been over 90 minutes and you're still not seeing logs, here are a few things you can try safely:

Thanks for you reply @Khadeer Ali I’m still not seeing the expected logs, even after recreating the diagnostic settings. While I do see entries under the AzureDiagnostics table with ResourceProvider =="MICROSOFT.SERVICEBUS", there are no logs appearing under AZMSOperationalLogs. I’m specifically trying to obtain logs related to service bus message delivery failures, and as I understand, this information should be captured in AZMSOperationalLogs.
@Khadeer Ali Any assistance with this would be greatly appreciated, as I’m unable to determine why the AZMSOperationalLogs table isn't showing any logs.

Arvind Vijay Vergiya, You need to have a Log analytics Reader role to retrieve the operational logs. Could you confirm if you add the same in your environment!
@Madugula Jahnavi I’ve been assigned the Log Analytics Reader role on the Log Analytics workspace, but I’m still unable to see any logs. I waited for an hour after the role assignment, but the issue persists. Anything else to consider?
Arvind Vijay Vergiya, I have initiated a private chat to discuss more on the issue. Could you respond over there!
responded.
Thanks for sharing the details.
@Arvind Vijay Vergiya Can you check the below suggestions and let us know if that helps?
@SadiqhAhmed-MSFT Thanks for your response. Yes updating to resource specific helped.

@Arvind Vijay Vergiya Is the configuration in Diagnostic Settings has the toggle on “Resource specific?”
It should be if you want logs to get ingested to dedicated tables instead of AzureDiagnostics. Hope this helps!
