Documentation forServer & Application Monitor
Monitoring your applications and environment is a key capability of Hybrid Cloud Observability and is also available in a standalone module, Server & Application Monitor (SAM). Hybrid Cloud Observability and SAM are built on the self-hosted SolarWinds Platform.

Display application dependency data in SAM

As Application Dependency polling and Connection Quality polling (if enabled) occur, the latest data populates these parts of the SolarWinds Platform Web Console:

  • The Application Connections widget on Node Details and Application Details views, as described next.
  • The Connection Details page that you can access via the Application Connections widget.

Application Connections widget

The Node Details and Application Details views display the Application Connections widget if Application Dependency polling detects these types of dependencies:

  • Application-to-application, including application processes
  • Application-to-node
  • Node-to-application

The Application Connections widget does not appear automatically on cloned, custom versions of Node Details and Application Details views.

Sample data appears in the Application Connections widget if no dependencies are detected, or if a node does not host an application dependency agent plugin. To deploy agents and agent plugins, assign at least one application monitor to each node you want to monitor.

If Connection Quality polling is enabled, the Application Connections widget displays the following data about TCP connections:

Similar to Spotlight functionality in AppStack, you can click connection types and status indicators at the top of the widget to filter data.:

Interpret colors and symbols in the Application Connections widget

SolarWinds Platform products use icons as a visual language to describe the status of items such as nodes, interfaces, events, or alerts. Values that exceed SolarWinds Platform thresholds appear bold on a colored background, as shown next.

Gray indicates that either:

  • The current status of a node or application is Unknown, or

  • Displayed data is restricted by SolarWinds Platform account limitations.

    To display

    You must have permission to view

    Node-to-node links

    Both parent nodes.

    TCP connections and statistics about latency and packet loss

    Both parent entities — either nodes or applications.

    Applications and application processes linked to a node

    The parent node.

    Network connection thresholds for a node

    The parent node.

For a more granular picture of dependencies, use the Connection Details page, as described next.

Connection Details page

If Connection Quality polling is enabled, the Connection Details page can show the entire communication stack between nodes with dependencies, making it a unique troubleshooting tool.

Data displayed on the Connection Details page includes:

  • The application name and detected process names, such as mysql.exe.
  • Monitored TCP metrics, including:
    • CPU: The percentage of CPU utilization.
    • P-MEM: The amount of physical memory used.
    • V-MEM: The amount of virtual memory used.
    • R-IOPS: Read input/output operations per second.
    • W-IOPs: Write input/output operations per second.
  • The port used by the application process.
  • Latency and packet loss metrics (if Connection Quality polling is enabled).
  • Latest Events details.

You can also use the Commands menu to configure thresholds, initiate polling, or hide events.

To access the Connection Details page:

  1. Access a Node Details view or Application Details view in the SolarWinds Platform Web Console.

  2. Click the > arrow next to a connection displayed in the Application Connections widget.

  3. The Connection Details page opens.

  1. (Optional) Click an option on the Commands menu to:

    • Configure network connection thresholds.

    • Initiate Application Dependency polling immediately.

    • Show or hide events.

  2. Menu options vary based on account permissions.
