Introduction<\/strong><\/p>\n\n\n\n

NSClient++ is a monitoring agent\/daemon for Windows systems that works with Nagios. This service allows Nagios to gather the performance metrics<\/em><\/p>\n\n\n\n

Prerequisites<\/strong><\/p>\n\n\n\n

    \n
  1. Credentials of Windows server<\/li>\n\n\n\n
  2. Nagios Host IP address<\/li>\n\n\n\n
  3. SSH (sudo) access of Nagios host<\/li>\n<\/ol>\n\n\n\n

    Implementation<\/strong><\/p>\n\n\n\n

    Step 1: Download NSClient from the below link on the Windows server

    https:\/\/sourceforge.net\/projects\/nscplus\/<\/u><\/a>

    Step 2: Start the installation process. Click on next<\/p>\n\n\n\n

    \"\"<\/a><\/figure>\n\n\n\n


    Step 3: Click on the generic option > Next<\/p>\n\n\n\n

    \"\"<\/a><\/figure>\n\n\n\n

    Step 4: Click on custom > Next<\/p>\n\n\n\n

    \"\"<\/a><\/figure>\n\n\n\n

    Step 5: Navigate the program and choose “will be installed on local hard drive” then next<\/p>\n\n\n\n

    \"\"<\/a><\/figure>\n\n\n\n

    Step 6: Leave the default path and click on next<\/p>\n\n\n\n

    \"\"<\/a><\/figure>\n\n\n\n

    Step 7: Specify the Nagios host IP and a new strong password. Then enable the NRPE server option and Insecure legacy mode > next<\/p>\n\n\n\n

    \"\"<\/a><\/figure>\n\n\n\n

    Step 8: Click on Install to initiate the installation and finish the installation<\/p>\n\n\n\n

    \"\"<\/a><\/figure>\n\n\n\n

    Step 9: On the Nagios host server, modify the check_nt command definition to include the password and restart the Nagios service<\/p>\n\n\n\n

    $ vi \/usr\/local\/nagios\/etc\/objects\/commands.cfg<\/strong><\/p>\n\n\n\n

    Change the definition of the check_nt command to include the -s argument (where PASSWORD is the password you specified on the Windows machine) like this:<\/p>\n\n\n\n

    define command{ command_name check_nt command_line $USER1$\/check_nt -H $HOSTADDRESS$ -p 12489 -s PASSWORD -v $ARG1$ $ARG2$ }

    $ service nagios restart<\/strong><\/p>\n\n\n\n

    Step 10: Edit the hostname and IP to configure the Windows server in Nagios

    $vi \/usr\/local\/nagios\/etc\/objects\/windows.cfg<\/strong>

    Note: Type hostname in the command prompt to find the hostname of the Windows server.<\/p>\n\n\n\n

    \"\"<\/a><\/figure>\n\n\n\n

    Step 11: Uncomment the windows.cfg file in \/usr\/local\/nagios\/etc\/nagios.cfg<\/p>\n\n\n\n

    \"\"<\/a><\/figure>\n\n\n\n

    Step 12: Verify the Nagios configuration files for any errors and restart Nagios<\/p>\n\n\n\n

    $\/usr\/local\/nagios\/bin\/nagios -v \/usr\/local\/nagios\/etc\/nagios.cfg<\/strong><\/p>\n\n\n\n

    \"\"<\/a><\/figure>\n\n\n\n

    $service nagios restart<\/strong><\/p>\n\n\n\n

    Step 13: Edit the nsclient.ini file from the path C:\\Program Files\\NSClient++ in the Windows server as mentioned below<\/p>\n\n\n\n


    ============================================================<\/p>\n\n\n\n

    # If you want to fill this file with all available options run the following command:<\/p>\n\n\n\n

    # nscp settings –generate –add-defaults –load-all<\/p>\n\n\n\n

    # If you want to activate a module and bring in all its options use:<\/p>\n\n\n\n

    # nscp settings –activate-module <MODULE NAME> –add-defaults<\/p>\n\n\n\n

    # For details run: nscp settings –help<\/p>\n\n\n\n

    allowed hosts = nagiosIP, 127.0.0.1<\/p>\n\n\n\n

    NSClientServer = 1<\/p>\n\n\n\n

    ; Undocumented key<\/p>\n\n\n\n

    NRPEServer = enabled<\/p>\n\n\n\n

    =============================================================<\/p>\n\n\n\n

    Step 14: Restart the NSClient service in the Windows server. Search service in the search bar and click on service<\/p>\n\n\n\n

    \"\"<\/a><\/figure>\n\n\n\n

    <\/p>\n\n\n\n

    Step 15: Search for the NSClient monitoring agent and click on restart<\/p>\n\n\n\n

    \"\"<\/a><\/figure>\n\n\n\n

    Step 16: Check on the Nagios Monitoring Web interface (https:\/\/nagiosip\/nagios) to ensure the Windows server has been added to that list<\/p>\n\n\n\n
