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.

Other SAM errors

The following compiled errors provide additional information and troubleshooting. You can also search for errors in the SolarWinds Success Center.

PowerShell 2.0 not installed

Issue: PowerShell 2.0 or later is not installed

Resolution: PowerShell is included in most versions of Windows Server but you can install it, if necessary. SolarWinds recommends using PowerShell 5.1.

The easiest way to set up a target server for PowerShell is to configure AppInsight for IIS on the node, which you can do in several way such as:

  • For an existing node currently managed via WMI, click List Resources on the Node Details view and select Microsoft IIS directly beneath AppInsight Applications. See Add AppInsight for IIS to an existing WMI node.
  • For a new node added via the Add Node Wizard, you'll see the same Microsoft IIS option as provided for existing nodes.
  • For multiple nodes, add them via the Discovery Wizard or assign AppInsight for IIS to nodes on the Manage Application Monitor Templates page.

PowerShell WebAdministration snapin not installed

Issue: PowerShell WebAdministration snapin is not installed.

Information: For legacy systems with IIS 7.0 (such as Windows 2008) PowerShell WebAdministration snapins are not part of IIS.

Resolution: The WebAdministration snapin was an option in old versions of PowerShell that is now integrated into PowerShell, which is included in most versions of Windows Server now. If necessary, install PowerShell and then configure AppInsight for IIS on nodes.

Polling IIS unsuccessful

Issue: Polling IIS servers is unsuccessful.

Possible Errors: OutOfMemoryException, Not enough storage, WinRM, WinRM not functioning properly, and so on.

Cause: IIS servers hosting many sites may cause polling to be unsuccessful.

Resolution: Increase the polling frequency and Memory per Shell Limit on the target node as needed following the instructions below. When finished, rerun the steps in Assign AppInsight for IIS to nodes in SAM.

You can also increase the polling frequency from the default value: 300 seconds (five minutes). If you see more than a five-minute gap in a graph, this value can be increased, as in any other SAM application.

  1. Click My Dashboards > Applications > SAM Summary, and then select an application to be taken to the Application Details view.
  2. Click Edit Application Monitor > Override template (next to Polling Frequency).
  3. Change to the desired value, and then click Submit.

To increase the memory per shell limit:

  1. Run PowerShell via Run as Administrator and execute the following command to get the actual value:

    winrm get winrm/config/Winrs

  2. Examine MaxMemoryPerShellMB. If the value is less than 512, run the following command to increase this value:

    Set-Item WsMan:\localhost\Shell\MaxMemoryPerShellMB NewValue -WarningAction SilentlyContinue;
    where the NewValue is the desired memory limit.

If the error persists, increase the value again.
