Reliable AWS monitoring and logging
The choice of logging solution should always be determined by the specific business requirements. It is crucial to align the logging strategy with what type of logs are needed and how they should be used. There are instances where we require custom solutions to retrieve logs, especially application logs that may not be easily accessible through CloudWatch or similar services. When we heavily rely on AWS native services, CloudWatch is indeed a robust choice. However, in certain scenarios, we might need integration capabilities with other tools, and if they can incorporate such features, it would enhance overall logging capabilities. I would rate it eight out of ten.
MuhammadAzhar Khan - PeerSpot reviewer

It allows me to save money by avoiding costs associated with AWS native services like CloudWatch or Amazon Prometheus. The ability to deploy on any cloud platform or environment, including Kubernetes, is a major advantage.
