We are using Cloudcheckr quite extensively, and it does support a very good Right Sizing tool. However, unless we deploy either Cloudwatch Agents or Datadog on each instance, we do not have any memory data, which makes it more difficult to rely on suggested instance sized.
Datadog is supported as a plugin to get that data into Cloudcheckr: eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fcloudcheckr.com%2F2018%2F05%2Fmemory-right-sizing%2F&data=02%7C01%7Ctom%40cloudar.be%7Ca0650d8d82244902a1c908d6e33d1a61%7C49c3d703357947bfa8887c913fbdced9%7C0%7C0%7C636946248919770391&sdata=QGUk4VdUpgyepm7P6Sejd89BahWDYzusToiC2E7rw8Q%3D&reserved=0 It would be very nice if you guys would offer us the same service Datadog does. It would quickly allow us to get all required data into Cloudcheckr without the need to deploy extra agents.
