Amazon CloudTrail and CloudWatch are two security pillars of your cloud. Majorly they must maintain logs, create metrics of sign-ins and notify the subscribed user about sign-ins. This way the user can react immediately. Since the reach of these two is incomparable, you can subscribe to them and have their services in more than 32 assigned regions. To ensure that Amazon CloudTrail and CloudWatch perform their duty without any delay, ensure that CloudTrail logs are delivered to CloudWatch alarms. For their configuration, you need to check their integrated status.
How to monitor Amazon CloudTrail Log files with Amazon CloudWatch Logs?
- First, you need to configure your trails to send log events to CloudWatch Logs.
- To evaluate log events for matches in terms, phrases or values, define the CloudWatch metric filters. For example, you can monitor events in Console Login.
- Assign CloudWatch metrics to the metric filter.
- Create CloudWatch alarms which are triggered by the thresholds and time periods specified by you. You can set up alarms to get notified when alarms are triggered so that you can take the required action.
- You can also automate a particular action in response to a particular alarm by configuring CloudWatch.

|Account Id||Applying account Id filter will display all the public snapshots for the selected account Id.|
|Region||Applying the region filter will display all the public snapshots corresponding to the selected region.|
|Severity||Applying severity filter will display public snapshots according to the selected severity type i.e. selecting critical will display all instances with critical severity. Same will be the case for Warning and Ok severity types.|
|Resource Tags||Applying resource tags filter will display those public snapshots which have been assigned the selected resource tag. For e.g., If the user has tagged some public snapshots by a resource tag named environment, then selecting an environment from the resource tags filter will display all those snapshots.|
|Resource Tags Value||Applying resource tags value filter will display data which will have the selected resource tag value. For e.g. – Let’s say a user has tagged some resource by a tag named environment and has a value say production (environment:production). Hence, the user can view data of all the resources which are tagged as “environment: production”. The user can use the tag value filter only when a tag name has been provided.|
|Compliance||Applying Compliance filter, you can further refine your security and health checks.|
