Today we're happy to introduce support for EC2 instance tags in our seamless AWS CloudWatch integration. When we import CloudWatch statistics for your EC2 instances, we record them with a source mapped to Amazon's unique instance ID's e.g. us-east-1.i-0076ac73 . While this makes it easy to load any single instance into one of our template dashboards, it's been impossible to load multiple related instances that comprise a cluster or service tier.
We've addressed this by adding intelligent support for EC2 instance tags. If you've set either librato:displayName or Name on an instance, we'll automatically use that value as a source display name i.e. alias. In the case both tags are set, librato:displayName takes precedence. Any changes to the tag's value will be detected and applied automatically.
You can search or wildcard match on either the original instance ID or the human-readable name specified in one of these tags. Whichever value matches your search will be used in the display. Let us know what you think!
