Inside vPV: a new way to monitor and troubleshoot virtualization performance


Administering the proliferation of virtualized infrastructures has become a full-time job—and then some. Virtualization administrators and Virtualization Subject Matter Experts (vSMEs) need to monitor many elements and domains, including the status, problems and wastage of virtualized servers, storage and network infrastructure. They also need troubleshooting tools and workflows to pinpoint problems, foresee capacity issues and identify underutilized systems.

It's a complex role to play, and vSMEs often spend too much time troubleshooting, find it difficult to see all the details and must constantly switch between too many tools.

HP's new Virtualization Performance Viewer has been developed as a real-time diagnostic and triage tool to improve how vSMEs and other virtualization administrators perform their roles, allowing them to quickly visualize data from a single console and begin to diagnose performance issues rapidly.

Here is an overview of how administrators can use vPV to troubleshoot, perform triage analysis and report on virtualized infrastructures.

1. Troubleshooting with Treemaps

The primary method that vPV uses to help admins identify patterns of problems across elements of similar type is Treemaps. These visual analytic representations of data trees are commonly used by financial analysts and stock trading websites to analyze complex patterns and behavior of financial instruments. Treemaps organize objects in structured hierarchies to represent multidimensional performance data using easily identifiable size and colour indicators.

In vPV, Treemaps (Fig. 1) provide an intuitive, visual way to identify issues with resource utilization and capacity. The dashboard displays an ordered listing of elements based on various factors, such as # of CPU cores or size of memory for hosts, or usage and latency for storage.

Admins can also group and filter their view of the hierarchy (Fig. 2), including an "interesting" subset, as well as easily switch between hosts, VM, storage and other views via a navigation dashboard.

2. Performing triage analysis with Workbench

In order to trend server utilization over different time ranges, vPV offers a Workbench view (Fig. 3). This standard Explorer-based UI allows vSMEs to quickly visualize performance of individual entities and perform triage as necessary by tracking across days, weeks, or a month. Performance counters also enable administrators to compare usage rates of systems in the near term.

3. Reporting performance trends

vPV offers multiple kinds of out-of-the-box reports available in both HTML and PDF format (Fig. 4). These include:

  • Inventory reports
  • Monthly trends of usage, activity
  • Top and bottom Utilization
  • Pie-chart of usage
  • Group and individual reports
  • Storage reports
  • Storage used by VM breakdown

Gaining visibility into virtualized infrastructures

It's important for vSMEs to quickly and easily troubleshoot performance issues, with both high-level views and the ability to drill down into specific performance bottlenecks for ad hoc analysis of performance issues. vPV provides this capability, with real-time insight into underlying virtualized environments.
