I'm not sure if you'll find anybody with much experience with that HP tool on here, one resource that might be worth looking at is the Gartner Magic Quadrant Report on APM Suites which has some high level comparisons between several vendors:
Thanks for the link. I jus had visited them and have made few points.
But, the link does not provide explanation on technical terms on why Appmon is better than HP Diagnostics. The point here is, since our competitor vendor's use HP Diagnostics, we are asked for a strong and elaborated reason when we try to suggest Appmon as our APM to our clients.
I kindly request you/team to share details on how Appmon stands better than HP Diagnostics so as to have successful proposal to our clients. Thanks in advance.
