Updating LEM Agents

Updated: September 15, 2017

This topic describes how to update LEM Agents on remote or local Windows computers.

Manually update LEM Agents on Windows installations using the LEM Local Agent Installer

Check the LEM release notes or ReadMe file first to be sure that the LEM Agent version you are planning to install is compatible with your installed LEM Manager version.

  1. Open the LEM console. See Log in to the LEM web console or Log in to the LEM desktop console for steps.

  2. Click Manage > Nodes, and then select Agent.

  3. In the Nodes pane, select the LEM Agent(s) to upgrade. Press <Ctrl> when you click to select more than one Agent.

  4. Select Add Node, and then select Agent node.

  5. Select one of the following:
    • Select Remote Installation if you need to push SolarWinds Log & Event Manager Agents to Microsoft Windows hosts across your network.
    • Select Local Installation if you will log in to the device that you want to install the Agent(s) on.
  6. If installing locally:
    1. Copy the setup.exe file to the computer's local hard drive.

      Security settings in newer versions of Windows may require you to copy the setup.exe files to the local hard drive on the computer.

    2. Log into the computer, right-click the installer, select Runas administrator, and complete the installation wizard.

Manually upgrade LEM Agents on Unix, Linux, Mac, and Windows hosts using LEM Remote Agent Installers

If you are installing LEM Agents on the far end of a WAN link, copy the Remote Agent Installer executable to the end of the WAN link and run it there. This will avoid using your WAN bandwidth to copy LEM Agents multiple times.

Check the LEM release notes or ReadMe file first to be sure that the LEM Agent version you are planning to install is compatible with your installed LEM Manager version.

Download the LEM Remote Agent Installer

The following LEM Agent installers are available from the SolarWinds customer portal:

  • Windows Agent Installer
  • Windows Remote Agent Installer
  • Linux Agent Installer (32-bit)
  • Linux Agent Installer (64-bit)
  • AIX Agent Installer
  • HPUX Itanium Agent Installer
  • Solaris Intel Agent Installer
  • Solaris Agent Installer
  • Mac OS X Agent Installer

Run the LEM Remote Agent installer

  • Specify a temporary folder on your computer to use for the installation process and click Next. The default is C:\SolarWindsLEMMultiInstall.
  • Enter the hostname of your LEM Manager in the Manager Name field and click Next. Do not change the default port values.

    Use the fully qualified domain name for your LEM Manager when you deploy LEM Agents on a different domain. For example, enter

  • Select Get hosts automatically or Get hosts from file (One host per line) and click OK.
    • Get hosts automatically uses a NetBIOS broadcast to identify hosts on the same subnet and domain as the computer running the installer.
    • Get hosts from file (One host per line) prompts you to browse for a text file that includes the hosts on which you want to install LEM Agents. Use this option for any of the following reasons:
      • You are deploying LEM Agents to computers on a different subnet than that on which the computer running the installer resides. Your computer may be able to access these subnets, but their hosts will not be recognized by the NetBIOS broadcast used to get hosts automatically.
      • You are deploying LEM Agents to a small segment of a large network, which could make choosing them from a list time prohibitive.
      • You are deploying LEM Agents in a network with a complex naming scheme, which could make choosing hosts from a list time prohibitive.

        The text file used for this option can contain hostnames, fully qualified domain names or IP addresses, each on their own lines. If DNS names are used, the computer running the installer must be able to resolve them.

  • Select the checkboxes next to the computers on which you want to install a LEM Agent.
  • Click Next.
  • Confirm the list provided is correct and click Next again.

  • Specify the Windows destination for the remote installation.
    • The default paths are provided for all supported Windows systems. We strongly recommend using the default paths, as the LEM Agent may not recognized as a service by Windows if it is not installed in a system folder.
    • The installer is set to automatically detect host operating systems by default, but you can also specify an operating system if all of the target hosts are running the same one.
  • Click Next.
  • Specify whether or not you want to install USB-Defender with the LEM Agent and click Next. The installer will include USB-Defender by default. To omit this from the installation, clear the Install USB-Defender checkbox.

    SolarWinds recommends installing USB-Defender on every system. USB-Defender will never detach a USB device unless you have explicitly enabled a rule to do so. By default, USB-Defender simply generates alerts for USB mass storage devices attached to your LEM Agents.

  • Confirm the settings on the Pre-Installation Summary and click Install.
  • Click Next after the installer extracts the installation files to the temporary directory.

The installer copies the extracted files to the installation directory.

After installation, the Agent automatically starts on each host. The installer removes the temporary installation directory from your computer. Find troubleshooting information here.
