Monitoring Weblogic on Windows

This article details setup steps specific to monitoring WebLogic when on a Windows platform.

Prerequisites

This document is assumes you have the following:

• A remote WebLogic server on a Windows platform

• A Nagios XI server with a network route to the WebLogic server

The monitoring of the WebLogic server is performed by the WLSAgent. This can be accessed via NCPA. You must install NCPA on your Windows server.

Setup on the Windows Server

1. Download wlsagent tar from below URL :

http://{nagiosxi_address}/nagiosxi/includes/configwizards/java-as/plugins/wlsagent.tar.gz

2. Extract the archive and put all files into C:\Program Files (x86)\Nagios\NCPA\plugins

3. Execute the following commands to generate and copy the WebLogic client library files:

cd $ORACLE_HOME\wlserver\server\lib

java -jar modules\com.bea.core.jarbuilder.jar

4. Copy the below files into : C:\Program Files (x86)\Nagios\NCPA\plugins\

• wlclient.jar

• wljmxclient.jar

• wlfullclient.jar

5. Create a run.bat file at C:\Program Files (x86)\Nagios\NCPA\plugins with the below content :

@ECHO OFF

java -Xmx32m -cp "C:\Program Files (x86)\Nagios\NCPA\plugins\wlsagent.jar;C:\Program Files (x86)\Nagios\NCPA\plugins\servlet-api-2.5.jar;C:\Program Files (x86)\Nagios\NCPA\plugins\jetty-servlet-7.6.2.v20120308.jar;C:\Program Files (x86)\Nagios\NCPA\plugins\wlclient.jar;C:\Program Files (x86)\Nagios\NCPA\plugins\lib\wljmxclient.jar;C:\Program Files (x86)\Nagios\NCPA\plugins\lib\wlfullclient.jar;" net.wait4it.nagios.wlsagent.core.WLSAgent 0.0.0.0 9090

6. Create a vbs Script to run the batch file in silent and invisible mode: Create a file wlsagent_run.vbs with the below content:

Set WshShell = CreateObject("WScript.Shell")

WshShell.Run chr(34) & "C:\Program Files (x86)\Nagios\NCPA\plugins\run.bat" & Chr(34), 0

Set WshShell = Nothing

7. Run the wlsagent_run.vbs by double clicking and the batch script will run as invisible/background.

8. To configure the Script to run at startup, open regedit and create a string value at the below location :

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

name: wlsagent_run

type: REG_SZ

Data: WScript C:\"Program Files (x86)"\Nagios\NCPA\plugins\wlsagent_run.vbs

9. To configure the Weblogic Monitoring Wizard from Nagios XI, see the The WebLogic Configuration Wizard section in Monitoring WebLogic.
