DevOps / AppDynamics Interview questions
Describe the Metric Browser in AppDynamics?
The Metric Browser is the Controller UI screen for browsing and plotting the raw metrics AppDynamics collects, organized in a tree structure by application, tier, node, and metric category, rather than pre-packaged into a fixed dashboard.
It's useful when a default dashboard doesn't show the exact metric you need — for example, drilling into a specific JMX counter, a hardware metric from a Machine Agent extension, or a raw error count for one node rather than the whole tier — and metrics found there can be added to a custom dashboard for ongoing tracking.
Data in the Metric Browser is stored at one-minute granularity initially and rolls up into coarser resolutions (such as 10-minute and 1-hour) over time, which is why very old data appears smoother and less spiky than data from the last hour.
