VisualAWR has been an interesting project for me while at Oracle. A great use case was for assessing customer DB workloads for health and capacity planning during Excite 20/20 engagements. Since moving on to AWS, I see opportunities to use this tool for assessing workload sizing (CPU/Mem/Storage/IOPS) for migration the cloud. Migration to cloud could mean lift-and-shift to RDS (Oracle flavor) or migration to other relational databases. Both approaches will need to know historical resource consumption for sizing of infrastructure required to run a database in the cloud, which is where this tool comes in.
I have uploaded a new version which now allows Batch processing of AWRMiner files. See download option to the right.
I have also opensourced this project on github: https://github.com/sfurlong/visual-awr
Looking forward to continued collaboration with folks interested in this project.
