Configure the NSX Controller instances for the management cluster and shared compute and edge cluster to forward log information to vRealize Log Insight in Region B by using the NSX REST API. To enable log forwarding, you can use a REST client, such as the Postman application.

Procedure

  1. Log in to the Windows host that has access to your data center.
  2. Start the Postman application and log in.
  3. Specify the request headers for requests to NSX Manager. 
    1. On the Authentication tab, configure the following authorization settings and click Update Request.
      Setting Value
      Type Basic Auth
      Username admin
      Password nsx_admin_password
      The  Authorization:Basic XXX header appears in the Headers pane.
    2. On the Headers tab, enter the following header details.
      Request Header Attribute Value
      Content-Type application/xml
      The  Content-Type:application/xml header appears in the  Headers pane.
  4. Contact the NSX Manager to retrieve the IDs of the associated NSX Controllers.
    1. Select GET from the drop-down menu that contains the HTTP request methods.
    2. In the URL text box next to the selected method, enter the following URL, and click Send.
      NSX Manager URL
      NSX Manager for the management cluster https://lax01m01nsx01.lax01.rainpole.local/api/2.0/vdn/controller
      NSX Manager for the shared compute and edge cluster https://lax01w01nsx01.lax01.rainpole.local/api/2.0/vdn/controller
      The Postman application sends a query to the NSX Manager about the installed NSX controllers.
    3. After the NSX Manager sends a response back, click the Body tab in the response pane.
      The response body contains a root <controllers> XML element that groups the details about the three controllers that form the controller cluster. 
    4. Within the <controllers> element, locate the <controller> element for each controller and write down the content of the <id> element. 
      Controller IDs have the controller-id format where id represents the sequence number of the controller in the cluster, for example, controller-4.
    5. Repeat the steps for the other NSX Manager.
  5. For each NSX Controller, send a request to configure vRealize Log Insight as a remote syslog server.
    1. In the request pane at the top, select POST from the drop-down menu that contains the HTTP request methods, and in the URL text box, enter the following URL.

      Replace controller-ID with the controller IDs you have written down.

      NSX Manager NSX Controller in the Controller Cluster POST URL
      NSX Manager for the management cluster NSX Controller 4 https://lax01m01nsx01.lax01.rainpole.local/api/2.0/vdn/controller/controller-4/syslog
      NSX Controller 5 https://lax01m01nsx01.lax01.rainpole.local/api/2.0/vdn/controller/controller-5/syslog
      NSX Controller 6 https://lax01m01nsx01.lax01.rainpole.local/api/2.0/vdn/controller/controller-6/syslog
      NSX Manager for the shared edge and compute cluster NSX Controller 4 https://lax01w01nsx01.lax01.rainpole.local/api/2.0/vdn/controller/controller-4/syslog
      NSX Controller 5 https://lax01w01nsx01.lax01.rainpole.local/api/2.0/vdn/controller/controller-5/syslog
      NSX Controller 6 https://lax01w01nsx01.lax01.rainpole.local/api/2.0/vdn/controller/controller-6/syslog
    2. In the Request pane, click the Body tab, select Raw, and using the drop-down menu, select XML (Application/XML).
    3. Paste the following request body in the Body text box and click Send.
      <controllerSyslogServer>
         <syslogServer>192.168.32.10</syslogServer>
         <port>514</port>
         <protocol>UDP</protocol>
         <level>INFO</level>
      </controllerSyslogServer> 
    4. Repeat the steps for the other NSX Controllers in the management cluster and in the shared edge and compute cluster.
  6. Verify the syslog configuration on each NSX Controller. 
    1. In the Request pane, from the Method drop-down menu, select GET, in the URL text box, controller-specific syslog URL from Step 5 and click the SEND button.
    2. After the NSX Manager sends a response back, click the Body tab under Response
      The response body contains a root <controllerSyslogServer> element that represents the settings for the remote syslog server on the NSX Controller.
    3. Verify that the value of the <syslogServer> element is 192.168.32.10
    4. Repeat the steps for the other NSX Controllers to verify the syslog configuration.
