pmurt,
We create Spectrum events from PAM via two methods:
1) Use the Create Event Operator, as Michael has suggested. Make sure that your "Attribute IDs" on the Operator match the Spectrum AlertMap files. (e.g. varbind 101 on PAM Operator field is mapped to varbind 101 on Spectrum AlertMap file). Also, make sure that you're pointing to the correct Spectrum Server on the Operator.
2) Use the HTTP Post Operator, and directly inject an alert into Spectrum via a REST call. There is information about how to do this in the "Web Services" documentation on the Spectrum side. Basically, you're crafting a (rather large) XML string in PAM using JavaScript, and sending it over to Spectrum.
