Individual beta features are enabled and disabled through the Lab Features dialog. Note that not all beta features will be available to all dyno types upon release to general audience. If there are additional features you would like to see let us know.
Response time summary
Similar to the memory summary, this feature displays summary metrics for response time, including the average of the median response times and the average of the 95th percentile median response times for the selected time interval.
Go language metrics
For Go users language runtime metrics, including heap and non-heap memory and GC activity, heap objects and Goroutine count are available. Please refer the the Language Metrics documentation for installation instructions and more details on the feature.
Once the metrics agent is installed plots are enabled through the Language Metrics beta feature.
HTTP Status codes
This beta feature replaces the Throughput plot with a new plot that shows request volume stratified by HTTP status code (e.g. 2XX, 3XX, 4XX and 5XX). The request volume is the total number of requests received for the resolution increment selected. For example a 24 hour time interval will display request volume in 10 minute increments. The throughput units are now displayed as the industry standard requests per second instead of requests per minute.
The labs feature allows you to reorder and hide individual metrics plots as a persistent, per process setting.
You can provide feedback through the Labs Feature dialog or by emailing the Dashboard Metrics team directly at email@example.com. Please drop us a line and let us know what you think.
