AppStack categories and data

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

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

Other Orion Platform products offer additional categories. Empty categories can be hidden through 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 a given 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 Settingsoption.

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 Definition
Groups   Use Groups more effectively manage your environment by organizing monitored objects logically, regardless of device type or location.
Applications         In SAM, an application is a collection of component monitors grouped together to collect specific metrics concerning the application as a whole.
Database Instances         A database is an organized collection of data. The displayed database instances including Microsoft SQL, MySQL, and Oracle.
Transactions         A transaction is a recording of web browser steps assigned to a specific location.
Steps         A step is a collection of actions. For example, the actions required to navigate to a specific URL make up one step.

A server is 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 Host is defined as a server running a Hypervisor for virtualization that can host multiple VM.
Virtual Clusters       Virtual clusters are built with 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 Datacenters       A virtual datacenter is 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 VMware virtual center (vCenter) server is a centralized management application that manages VMs and ESXi hosts centrally. Use a vSphere client to access vCenter Server and manage ESXi servers.
Data Stores         A data store is a repository of a set of data objects. These objects are modeled using classes defined in a database schema. A data store is a general concept that includes not just repositories like databases, but also simpler store types such as flat files. Some data stores represent data in only one schema, while other data stores 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, or LUN, is a number used to identify a logical unit, which is a device addressed by the SCSI protocol or Storage Area Network protocols which 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 is most often used to refer to a logical disk as created on a SAN.
NAS Volumes         Network-attached storage (NAS) is a type of dedicated file storage device that provides local-area network (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 LIFs through which it serves data to the clients. A VServer can either contain one or more 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.

In a cluster, a VServer facilitates data access. A cluster must have at least one VServer to serve data. VServers use the storage and network resources of the cluster. However, the volumes and LIFs are exclusive to the V-Server. Multiple Vservers can coexist in a single cluster without being bound to any node in a cluster. However, they are bound to the physical cluster on which they exist.

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.
