AppStack categories and data

By default, the following AppStack Environment categories are available in the Orion Platform:

  • Groups
  • Containers
  • Chassis
  • Applications
  • Database Instances (with Orion Integrated DPA)
  • Servers
  • Hosts
  • Virtual Clusters
  • Virtual Data Centers
  • Virtual Centers
  • Volumes

Other Orion Platform products offer additional categories. Empty categories can be hidden via the Change Layout Settings option in the drop-down menu.

The Category Status Summary (located to the right of each category) parses, enumerates, and displays the number of objects in each category, emphasizing the status as indicated by the colors. The Category Status Summary can be toggled to either display at all times, or only when categories are collapsed.

You can manage the setting through the Change Layout Settings option.

Supported categories and data

The following matrix outlines categories associated with the AppStack Environment view, which vary by SolarWinds product.

Category SRM SAM VMAN WPM DPA NPM Definition
Groups Manage your environment by organizing monitored objects logically into groups, regardless of device type or location.
Containers Lightweight, executable packages of software that include everything needed to run an application: code, system tools, system libraries, and settings. Containers isolate applications and their dependencies into self-contained units that can run anywhere without interfering with each other.
Chassis A physical structure that houses one or more servers.
Applications A collection of SAM component monitors grouped together to collect specific metrics concerning the application as a whole.
Database Instances An organized collection of data. The displayed database instances including Microsoft SQL, MySQL, and Oracle.
Transactions A recording of web browser steps assigned to a specific location.
Steps A collection of actions. For example, the actions required to navigate to a specific URL make up one step.

A computer capable of accepting requests from the client and giving responses accordingly. The server makes services, as access to data files, programs, and peripheral devices, available to workstations on a network.

Hosts A server running a hypervisor for virtualization that can host multiple VMs.
Virtual Clusters A group of VMs installed at distributed servers from one or more physical clusters. VMs in a virtual cluster are logically connected by a virtual network across several physical networks. Each virtual cluster is formed with physical machines or a VM hosted by multiple physical clusters.
Virtual Data Centers A centralized virtual repository to store, manage, and disseminate data related to a particular body of knowledge or pertaining to a particular business.
Virtual Centers A server that acts as a centralized management application to manage VMs and ESXi. Use a vSphere client to access vCenter Server and manage ESXi servers.
Data Stores A repository is a set of data object sets modeled using classes defined in a database schema. A data store may also store simpler types such as flat files. Some data stores represent data in only one schema, while others use several schemas for this task.
Volumes A volume, or logical drive, is a single accessible storage area with a single file system, typically resident on a single partition of a hard disk.
LUNS A Logical Unit Number (LUN) is used to identify a logical unit, which is a device addressed by the SCSI or SAN protocols that encapsulate SCSI, such as Fibre Channel or iSCSI. A LUN may be used with any device which supports read/write operations, such as a tape drive, but usually refers to a logical disk created on a SAN.
NAS Volumes Network-attached storage (NAS) is a type of dedicated file storage device that provides LAN users with centralized, consolidated disk storage through a standard Ethernet connection.

A storage pool (also called a RAID array) is a collection of disk drives that become a logical entity. When you create a storage pool, you select the desired capacity (number of disk drives) and assign a RAID level to it which provides a redundancy level.


A virtual storage server (VServer) contains data volumes and one or more logical interfaces (LIFs) through which it serves data to clients. A VServer can contain multiple FlexVol volumes, or a single Infinite Volume.

A VServer securely isolates the shared virtualized data storage and network, and appears as a single dedicated server to its clients. Each VServer has a separate administrator authentication domain and can be managed independently by a VServer administrator.

Storage Arrays Storage Arrays consist of two or more disk drives built into a stand-alone unit. Storage arrays provide increased availability, resiliency, and maintainability by using existing components (controllers, power supplies, fans, and so on) often up to the point where all single points of failure are eliminated from the design.

This AppStack provides a sample of categories and multiple nodes in various health states:
