AppStack categories and data

Table of contents
No headers

The following matrix outlines all of the categories associated with the AppStack Environment view. Different categories are available with each SolarWinds product, as indicated in the Product column

Category Definition Products
Groups Groups enable you to more effectively manage your environment by giving you the ability to logically organize monitored objects, regardless of device type or location.
  • SRM
  • SAM
  • VMan
  • WPM
Applications In SAM, an application is a collection of component monitors grouped together to collect specific metrics concerning the application as a whole.
  • SAM
Transactions A transaction is a recording of web browser steps assigned to a specific location.
  • WPM
Steps A step is a collection of actions. For example, the actions required to navigate to a specific URL make up one step.
  • WPM
Servers

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.

  • SAM
  • VMan
Hosts A Host is defined as a server running a Hypervisor for virtualization. (E.g. It hosts multiple virtual machines.)
  • SAM
  • VMan
Virtual Clusters Virtual clusters are built with VMs installed at distributed servers from one or more physical clusters. The 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.
  • SAM
  • VMan
Virtual Datacenters A virtual datacenter is a centralized virtual repository for the storage, management, and dissemination of data and information organized around a particular body of knowledge or pertaining to a particular business.
  • SAM
  • VMan
Virtual Centers A VMware virtual center (vCenter) server is a centralized management application that lets you manage virtual machines and ESXi hosts centrally. The vSphere client is used to access vCenter Server and ultimately manage ESXi servers.
  • SAM
  • VMan
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.
  • VMan
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.
  • SRM
  • SAM
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.
  • SRM
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.
  • SRM
Pools

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 will provide a redundancy level.

  • SRM
VServers

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.

  • SRM
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.
