AWS CloudWatch is a monitoring tool for tracking AWS application health and resource use. It's commonly used to help:
The data and reports that AWS CloudWatch provides let users keep track of application performance, resource use, operational issues, and constraints. This helps organizations resolve technical issues and streamline operations. CloudWatch is most commonly used with Elastic Compute Cloud (EC2) instances and can also monitor Amazon Elastic Block Store (EBS) volumes, Elastic Load Balancers (ELBs), and instances of Amazon Relational Database Service (RDS). It also can extend beyond these core services to intake custom data from external sources. Users choose CloudWatch for its automatic integration with AWS services and its flexibility and scalability.
AWS CouldWatch comes in pricing tiers, a free and paid tier. The paid tier of CloudWatch has no upfront fees or commitments and is billed based on usage at the end of the month. Keep in mind, CloudWatch prices do vary by region and are subject to change. Below are the current prices listed by Amazon:
Amazon CloudWatch is configured out-of-the-box to integrate with EC2, offering two levels of monitoring capabilities:
Additional AWS services that CloudWatch can monitor automatically include the following:
Amazon CloudWatch is capable of monitoring custom metrics from data produced by your applications, scripts, and services. Custom metrics can include anything, from web page load time or the amount of work performed by your application. PutMetricData API is the easiest way to get started with custom metrics, but you can also use several other applications and tools offered by AWS partners.
Amazon CloudWatch offers Basic AWS Monitoring at no cost for EC2 instances. Data included in Basic monitoring includes CPU load, disk I/O, and network I/O metrics, which are collected in five-minute intervals with two-week storage.
Beyond its automatically configured monitoring capabilities, CloudWatch can be extended to monitor metrics from additional AWS services and even external applications. Through API requests, users can enable the same core functionality of CloudWatch for their custom data. CloudWatch also can function for basic monitoring of system logs, allowing users to track and analyze specific metrics.
The CloudWatch dashboard interface allows users to create custom graphical views across their AWS services. These can include both real-time data and historical data for up to a two-week maximum.
Users also can set alarms that will trigger whenever a metric crosses a specified limit, allowing them to take quick actions on real-time data or easily spot resources that are being underutilized. Some responsive actions can even be automated using a rules engine built into the service.
AWS Cloudwatch is a monitoring tool that provides visibility into the performance of your AWS resources and applications. AWS CloudTrail is a logging tool for AWS account activity and API usage for compliance, monitoring, and risk auditing.
Using AWS CloudWatch, you can view log data on a stream-by-stream basis. All log data is sent by the CloudWatch Logs agent to CloudWatch logs. The data can easily be reviewed by the time range specified for the log data.

Using Sumo Logic, you can collect CloudWatch logs using our AWS Lambda function to subscribe to your CloudWatch Log Group. Our AWS Lambda function converts the CloudWatch log format into a format compatible with Sumo Logic, then POSTs the data directly to a Sumo HTTP Source. This is the preferred method for the following types of data: Custom CloudWatch log data, Amazon VPC Flow logs and AWS Lambda logs.
