hi Albert,
I think I'm going to be a little bias as I work for IBM and my focus is on our monitoring & analytics offerings. I'd be curious to learn more about your requirements. I'd be happy to review our capabilities in our IBM Performance Management offerings.
Here's a link for IBM Performance Management
https://www.ibm.com/marketplace/cloud/application-performance-management/ca/en-ca
There's information on key features, capabilities and you can even sign up for a free 30 trial so you can evaluate it yourself.
