Which of the following are features of Amazon CloudWatch Logs
Amazon CloudWatch is a component of Amazon Web Services that provides monitoring for AWS resources and the customer applications running on the Amazon infrastructure. Show
CloudWatch enables real-time monitoring of AWS resources such as Amazon Elastic Compute Cloud (EC2) instances, Amazon Elastic Block Store (EBS) volumes, Elastic Load Balancing and Amazon Relational Database Service (RDS) instances. The application automatically collects and provides metrics for CPU utilization, latency and request counts. Users can also stipulate additional metrics to be monitored, such as memory usage, transaction volumes or error rates. Users can access CloudWatch functions through an application programming interface (API), command-line tools, one of the AWS software development kits or the AWS Management Console. The CloudWatch interface provides current statistics that users can view in graph format. Users can set notification alarms to be sent when something being monitored surpasses a specified threshold. The app can also detect and shut down unused or underused EC2 instances. Amazon CloudWatch is designed for AWS users, including DevOps engineers, IT managers, cloud developers and site reliability engineers. CloudWatch featuresCloudWatch enables users to collect and view monitoring data for AWS infrastructures in a single platform. CloudWatch includes specific features for data collection, monitoring, automated actions, analysis and compliance and security. What does Amazon CloudWatch do?
