Data collection and display

SAV scans devices (servers and network and storage devices) and draws maps based on data that is collected in real-time results of a SAV snapshot. Device data is captured directly from servers and then recorded in snapshots. Network device data is scanned and then recorded in scan results by NAS — where it is retrieved by the SAV from the Network Automation data model. Storage data that relates to the selected device is scanned from the SE data model.

When you launch SAV, a set of programs runs on the selected managed devices and captures data. This scanning process collects data about processes running on those devices and the connections between them. It also collects detailed configuration information and current run-time state information about connections and processes. SAV then merges the server data, network, and storage device data to show how servers, interfaces, switches and switch ports, file systems and local and remote storage are connected together.

When you click Refresh Snapshot on the SAV toolbar, SAV creates a new snapshot that captures all the information gathered when you scan a business application (and the servers and devices it runs on) as well as your business application definitions.

SAV uses information gathered from SA, NA, and SE, leveraging the architecture to collect more data on-demand (such as processes that are running, open ports, and the number of users logged in). It also maps business application data to visualize and analyze your operational environment.

SAV collects and displays the following information about managed servers, network, and storage devices:

  • Processes and process families (potentially matching application signatures) that are running on managed servers
  • TCP and UDP connections between these processes
  • Detailed configuration information
  • Current runtime information about servers, connections, and processes
  • File systems on servers and how they are used by process families, are mapped to fibre channel ports, and are reliant on local and remote storage
  • Servers, interfaces, adapters, switches and vSwitches, and switch port connections
  • Local and remote storage devices and how they connect to servers, SAN switches, and other storage devices

See Processes, process families, and extended process families for an explanation of how SAV interprets this data. See Filtering SAV data for instructions on how to search the data that was collected by object type, such as by process family, network interface, and so on.
