The best thing about resMo is that it helps in monitoring every single AWS resource which are created using API Gateway or Lambda functions without any manual intervention from our side! I am able use this tool very easily by just logging into my account dashboard whenever need arises rather than going through different tabs of console one after another searching out each individual information needed like its IP address etc., In addition we can see detailed reports as well when required via email too if not logged onto website itself but then again you have option available at your disposal always while viewing online so dont worry!! Not much dislike apart form some minor bugs here n there once upon time since last couple years ago though nothing major has happened till now i guess.
It's definitely worth giving tryout because even free version works perfectly fine provided u know what exactly ur looking4n eveything gets.
