Logstorage, developed by Infoscience Corporation, Japan, offers an integrated log management system that allows you to consolidate your logs and manage them from a browser. You can create various complex searches, analyze statistics, set up alerts and reporting on AWS Config data. For example, you can search which instances are using approved AMIs, or which security groups were recently updated. You also get a visual report of the configuration snapshot delivered by AWS Config. Logstorage is one of the leading providers of integrated log management solutions in Japan.
Logstorage is not limited to collecting AWS Config data but can also handle textual logs in any format(eg. AWS Cloudtrail, Amazon CloudWatch Logs)
