LEM Remote Agent deployment using Patch Manager issue

Updated June 19, 2017

Overview

This article describes issues and limitations during remote deployment of LEM Agent using a patch management solution either from SolarWinds Patch Manager or from a third party patch management vendor.

 

For example, The following issues occurred when deploying LEM agent using QDP using the local agent installer with -i silent switch.

  • The LEM Agent was deployed but the node is not displayed in the Manager Console and the Agent log indicates that it is unable to bind to 127.0.0.1:xxxxx. This is because the installer.properties file was not copied to the local machine and it instead created a temporary location there the files were copied. 
    (Wed Jun 14 13:56:58 BST 2017) EE:ERR [Communications] {ComModuleSpop:21} IP is null so cannot open connection to parent
    (Wed Jun 14 13:57:38 BST 2017) II:INFO [AgentMessageCentralImpl] {XML Communication Reconnector - 1:40} Trying to establishing connection from the Agent to the Manager on localhost/127.0.0.1:xxxxx
    (Wed Jun 14 13:57:39 BST 2017) WW:WARNING [AgentMessageCentralImpl] {XML Communication Reconnector - 1:40} Unable to establishConnection with the Manager. Reason java.net.ConnectException: Connection refused: no further information: localhost/127.0.0.1:37891
  • Permissions and local policy settings have been exhausted on the agent machine deployed. 
  • Uninstalled and re-deployed via the QDP console and it resulted in the same issue.
  • Installing the agent locally works.

Environment

  • All LEM versions
  • LEM Agent 6.3.1

Cause 

This is caused by multiple environmental issues depending on the vendor used.

Resolution

 

Perform the following workaround during the deployment:

  1. Select the local agent .exe file instead of remote agent installer and add the -i silent switch while creating the deployment package.
  2. Download and save the installer.properties file in the same folder where the .exe file is located.
