AppStackis a specialized visualization tool designed to show the "stack" of dependencies between different layers of an IT environment. According to theSolarWinds Platform Administrator Guide, AppStack has two defining characteristics:
* Automatic Relationship Gathering (A): The tool uses the data already collected by various modules (SAM, VMAN, SRM) toautomaticallymap how applications, database instances, servers, virtual hosts, and storage volumes are linked. This eliminates the need for manual manual line-drawing in most cases.
* Customizable Visual Mapping (B): It provides aninteractive environment viewwhere users can filter by status, application name, or site to see a visual map of the infrastructure. This allows a user to click on a failing application and see exactly which virtual host or storage array might be causing the failure due to its relationship.
Options C and D describePerfStack(Performance Analysis), which is the tool used for time-series correlation and dragging metrics onto charts. AppStack focuses on thestructureof the environment, whereas PerfStack focuses on theperformance dataof the entities within that structure.
