VMware vCenter Operations V5

VMware vCenter Operations V5 is no longer supported in LoadMaster.

1 Introduction

The VMware vCenter Operations (vCOPS) Management Suite provides comprehensive visibility and insights into the performance, capacity and health of your infrastructure. vCenter Operations Manager collects performance data from each object at every level of your virtual environment, from individual virtual machines and disk drives to entire clusters and data centers. It stores and analyses the data, and uses that analysis to provide real-time information about problems, or potential problems, anywhere in your virtual environment.


The KEMP Virtual LoadMaster (VLM) operates within the vCOPS architecture to provide load balancing functionality. vCOPS can instantiate a LoadMaster, monitor it and provide detailed statistics and information regarding its health within the vCOPS architecture.


With vCOPS, information can be gathered from the LoadMaster to form aggregated dashboard views combining the resource consumption data that is already natively available, along with statistics relevant to how each VM is performing in the context of the applications that they serve. The LoadMaster’s proximity to virtual application server instances, and its role as an intermediary connection point between clients and VMs, puts it in an ideal location to provide this data to vCOPS for dashboard and other information rendering.

1.1 Document Purpose

The purpose of this document is to describe the various features and functionality that can be used within the vCOPS Manager relating to the KEMP LoadMaster. For further information on vCOPS in general, refer to the VMware documentation.

This document relates to vCOPS version 5. Refer to the VMware vRealize Operations Version 6, Installation and Feature Description for steps relating to vROps version 6 and above.

1.2 Intended Audience

This document is intended to be read by anyone who is interested in finding out how to utilize the vCOPS with the KEMP LoadMaster.

2 Using vCOPS with the LoadMaster

2.1 Prerequisites

Before using vCOPS with the LoadMaster, the RESTful API interface must be switched on in the LoadMaster. This allows vCOPS and the LoadMaster to communicate. To enable the RESTful API interface on the LoadMaster, follow the steps below:

1. In the main menu of the LoadMaster Web User Interface (WUI), select Certificates & Security > Remote Access.


2. Select the Enable API Interface check box.

2.2 Installation

To make the LoadMaster work with vCOPS, follow the steps below:

1. Download the LoadMaster vCOPS installation (.pak) file.

2. Log in to the vCenter Operations Manager Administration page.


3. Select the Update tab.

4. Click Browse.

5. Browse to and select the .pak file.

6. Click Update.

7. Click OK.

8. Select the I accept the terms of this agreement check box.

9. Click OK.

10. Click OK to confirm the update.

11. Wait for the update to complete. The progress bar will disappear when the update is complete.

The update can take several minutes to complete.

2.3 Add the LoadMaster Adapter

After importing the .pak file, the LoadMaster adapter needs to be added. To do this, follow the steps below:

1. Log into the vCenter Operations Manager page at https://<IPAddress>/vcops-custom.

Add the LoadMaster Adapter.png

2. In the menu at the top, select ADMIN and SUPPORT.

7. Reload the page by refreshing the browser. The LoadMaster adapter should appear in the list of adapters.

2.4 Add a LoadMaster Adapter Instance

If you have just added the LoadMaster adapter, wait for a few minutes before adding an instance because it takes time to initiate. If the instance is added too soon, a failure will occur when you save or test the credentials.

An instance of the adapter needs to be created for every Virtual LoadMaster (VLM) to be monitored. To add an instance, follow the steps below:

Add a LoadMaster Adapter Instance.png


Add a LoadMaster Adapter Instance_1.png

2. Click the Add New Adapter Instance button.

Add a LoadMaster Adapter Instance_2.png

3. Select the Collector.

If vCenter Operations Standard Server is not available to select in the Collector drop-down list it means that the LoadMaster adapter has not initiated yet. If this happens, wait a few minutes and try adding the new adapter instance again.

4. Select the type of adapter. In this case it is LoadMaster Adapter.

5. Click Add to input the LoadMaster credentials.

Add a LoadMaster Adapter Instance_3.png

6. LoadMaster Adapter will already be selected in the Adapter Kind drop-down list. Select LoadMaster Credentials from the Credential kind drop-down list.

7. Enter an Instance name for the credentials.

The credentials can be reused.

8. Enter the IP Address of the LoadMaster that you want to collect statistics for.

If the default self-signed certificate of the LoadMaster WUI has been updated with a trusted certificate, a valid subject or subject alternative name from the certificate should be entered in the IP address text box to establish the connection.

9. Enter the Username and Password of the LoadMaster.

The default LoadMaster username is bal.

10. Click OK.

Add a LoadMaster Adapter Instance_4.png

11. Enter an Adapter Instance Name.

12. Click Test.

If the test fails and you are sure the credentials are correct, the instance may have been added too soon after the adapter was added in the Add the LoadMaster Adapter section. If this happens, wait for a few minutes and then add the instance again. Do this by clicking Cancel and following steps 2 to 12 above. There is no need to create the credential instance again if it has already been created. You can select the credential instance from the Credential drop-down list if it has already been created.

The API interface must be enabled on any monitored LoadMasters for this to work. Refer to the Prerequisites section for instructions on how to enable it.

13. When the test is successful, click OK.

Do not click OK unless the test is successful.

14. Click OK again.

2.5 Environment Overview

The environment overview screen provides you with an overview of all of the adapters.
