Store and Monitor OS & Application Log Files with Amazon CloudWatch

Today we are introducing a powerful new log storage and monitoring feature for Amazon CloudWatch. You can now route your operating system, application, and custom log files to CloudWatch, where they will be stored in durable fashion for as long as you’d like. You can also configure CloudWatch to monitor the incoming log entries for any desired symbols or messages and to surface the results as CloudWatch metrics. You could, for example, monitor your web server’s log files for 404 errors to detect bad inbound links or 503 errors to detect a possible overload condition. You could monitor your Linux server log files to detect resource depletion issues such as a lack of swap space or file descriptors. You can even use the metrics to raise alarms or to initiate Auto Scaling activities.
