We are looking for a flexible Business Activity Monitoring package affordable enough for the average SMB and that can integrate reasonably well with our .NET applications (SOAP/REST interface is just fine).
I am aware that BizTalk has a BAM component, but we are not interested in using BizTalk as a messaging solution and I hate to buy a BizTalk license and get saddled with the heft of BizTalk just for the integrated BAM capabilities.
Ideally we are looking for a BAM solution that is middleware/vendor agnostic.
The alternative to buying a BAM package is, of course, building a customized BAM solution, but I'd like to reserve that option as a last resort.
I'm interested in any experiences, positive or negative, you may have had using a commercial (or open source) BAM product.
