I am attempting to configure component based message alerting with PO 7.5, and while it seems straightforward I am not seeing any alert generated for failed messages. I followed the steps in this blog: https://blogs.sap.com/2012/03/25/michals-pi-tips-component-based-message-alerting/, but when I navigate to Message Alert Configuration: Overview > Alert Log I see no alerts. I have configured an alert rule with message header rules, i have chosen the components that are relevant, and the message statuses I want to alert on.
I can see the message errors in the Message Monitor, but no alert is being triggered. As best I can tell, the message that failed meets all of the alert criteria I specified. The status of the alert is 'successful' and it is enabled.
