Amazon RDS Performance Insights is a database performance tuning and monitoring feature that helps to asess the load on a database, and determine when and where to take action. Performance Insights helps non-experts to detect performance problems with a dashboard that visualizes database load. Performance Insights uses lightweight data collection methods that don’t impact the performance of your applications, and makes it easy to see which SQL statements are causing…

Foglight is a database performance management suite from Quest, with modules to perform cloud analytics, network performance monitoring and virtualization management, scaling to a broad, cloud / virtualization focused IT infrastructure monitoring solution.
When you need to monitor your database at low level metrics such as query load or CPU usage at some point in time. You can also use it to understand which component is a heavy load on your DB. It is a great tool for routine monitoring of your DB and to help plan for capacity. I would not use it as an exclusive source for scaling your DB though since the is not long-term or very granular data to be able to run a thorough analysis on peaks of predictive analysis.
It really depends on why my colleague is evaluating Foglight. If it is for Database monitoring and management, I highly recommend it. If it is for anything else, I would encourage them to look at others in this space.
Foglight allows detecting and diagnosing performance problems simplifying hybrid environments, it is a solution that has perfect features which work in a flexible and intuitive way, it allows database performance in a safe and fast way. It works perfectly with nothing else to add.
Amazon RDS Performance Insights is a out of the box plug and use solution for AWS with a press of a button, whereas Prometheus would require a lot of configuration and deployment and the learning curve is slower, making it not so user friendly. Datadog on the other hand offers similar capabilities but at a much higher cost. With that in mind, Amazon RDS Performance Insights is the choice to integrate with your AWS services quickly and affordably.
Foglight was chosen years ago as a replacement for Groundwork. After 2.5 years of implementing Groundwork things were still not complete and the decision to go with a more formalized solution was made. Foglight installed easily and quickly nearly across the board and the full implementation for complex infrastructure was completed (with no Professional Services) by us in under 4 months. Nagios is a wonderful toolkit but you have to be ready to build what you need. It's flexibility and breadth are excellent features but with that comes the need to define things very tightly lest you embark on the project that never ends (see above about Groundwork). Dynatrace is an excellent APM tool and has advanced analytics but as a general infrastructure monitoring tool it is actually very expensive and to be honest does not have the same focus and full feature set that it does on it's APM (which to be fair is it's wheelhouse). vROPs (we also have) is a wonderful tool but focused (and rightly so) on satisfying the VMware engineers in the crowd and doesn't put itself out there too far to make things palatable for the non-engineering crowd.
