How Ylastic Uses Twilio
Ylastic initiates a phone call to the Ylastic account holder when their in-cloud virtual server triggers a notification (e.g. load spike).
Voice notifications can also be generated when:
- Amazon CloudWatch monitoring thresholds are triggered
- Amazon AutoScaling actions have been initiated by Amazon EC2
- Health status changes for Amazon Web Services including EC2, S3, CloudFront, SimpleDB, or SQS.
Example of a Voice Alert Generated by Ylastic
According to the Ylastic blog,
you can get a voice alert when any of these parameters for a Amazon CloudWatch enabled instance exceed the threshold you’ve set:
- CPU Utilization
- Bytes read from all disks for instance
Bytes written to all disks for instance
Completed read operations from all disks for instance
Completed write operations from all disks for instance
Bytes received on all network interfaces for instance
Bytes sent out on all network interfaces for instance
Latency for the load balancer
Number of requests processed by the load balancer
Number of unhealthy instances for load balancer
You can also get voice alerts when EC2 initiates Auto Scaling
activities for your scaling group, and when a service health change is
detected for EC2, S3, SQS, SimpleDB and CloudFront.
