Amazon CloudWatch Integration

Create alerts in ilert from CloudWatch alarms.
Amazon CloudWatch is a monitoring service for AWS cloud resources and applications running in the AWS Cloud. Amazon CloudWatch can monitor AWS resources, such as EC2 instances, Amazon DynamoDB tables, and Amazon RDS DB instances, as well as application and service generated metrics and log files.
With ilert's CloudWatch integration, you can automatically create alerts in ilert from CloudWatch alarms. That way, you will never miss a critical alert and always alert the right person using ilert's on-call schedules, automatic escalation, and multiple alerting channels. When CloudWatch creates an alarm, ilert will alert the on-call person through their preferred channel, including SMS, phone calls, push notifications and Slack. ilert will automatically escalate to the next person, if the alert is not acknowledged. ilert also lets you define alerting rules based on support hours and delay alerts until your support hours start.
