VMware vRealize Operations V6

 

1Introduction

The VMware vRealize Operations (vROps) Management Suite provides comprehensive visibility and insights into the performance, capacity and health of your infrastructure. vRealize 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 centres. 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.

Figure 1‑1: vROps example

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

With vROps, 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 vROps for dashboard and other information rendering.

1.1Document Purpose

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

  3. Click Save Settings.
  4. Click OK.
  5. Click Close.

2.3LoadMaster Dashboards

Three LoadMaster dashboard are automatically created when a LoadMaster instance is added:

  • LoadMaster Health Snapshot: This provides an overview of the health of the LoadMaster, Virtual Services and Real Servers
  • LoadMaster Resource View: This provides details about each of the LoadMaster resources
  • LoadMaster Resource Metric Graphs: This provides metrics on each of the LoadMaster resources, such as the number of connections per second.

Figure 2‑11: LoadMaster dashboards

These are available in the Dashboard List on the Home page of vROps Manager.

2.4Collection Interval

By default, the statistics get collected by vROps every five minutes.

The collection interval can be changed by following the steps below in the vROps Manager:

Figure 2‑12: Environment Overview

  1. Select the Administration (cog) icon in the top left section.
  1. Select Environment Overview on the left.

  1. Select the relevant adapter instance on the right panel.
  2. Click the Edit Resource (pencil) icon.

Figure 2‑15: Collection Interval

  1. Change the value of the Collection Interval.

Statistics in the LoadMaster are gathered in real time. The details shown in vROps are a snapshot of the statistics at the moment it polls the LoadMaster.

  1. Click OK.

2.5Discovering Virtual Services and Real Servers

When adding a LoadMaster adapter instance, there is a setting called Auto Discovery which is set to true by default.

If Auto Discovery was set to true when the instance was added, there is no need to follow the steps in this section because the Virtual Services and Real Servers will be added automatically.

If Auto Discovery was set to false when the instance was added, follow the steps below to manually add the Virtual Services and Real Servers:

Figure 2‑16: Environment Overview

  1. Select Administration (cog icon) in the top left section.
  1. Select Environment Overview on the left section.
