Since December 2017 Amazon provides a CloudWatch Agent for Windows and Linux operating systems included disk and previously not available memory information,[2] previously Amazon provided example scripts for Linux instances to collect OS information.[3][4] The data is aggregated and provided through AWS management console. It can also be accessed through command line tools and Web API's, if the customer desires to monitor their EC2 resources through their enterprise monitoring software. Amazon provides an API which allows to operate on CloudWatch alarms.[5]
The metrics collected by Amazon CloudWatch enables the auto-scaling feature to dynamically add or remove EC2 instances.Template:Sfnp The customers are charged by the number of monitoring instances.
Since May 2011, Amazon CloudWatch accepts custom metrics[6] that can be submitted programmatically via Web Services API and then monitored the same way as all other internal metrics, including setting up the alarms for them, and since July 2014 Cloudwatch Logs service is also available[7].
