ClientVantage Agentless Monitoring

The Compuware ClientVantage Agentless Monitoring solution reaches all local and remote employees, customers and business partners. How can Vantage provide me complete visibility into end-user experience?

The ClientVantage Agentless Monitoring solution is an effective, non-intrusive choice for web applications that are accessed by employees, partners and customers outside the corporate enterprise or from the corporate network (intranet or extranet). It complements ClientVantage agent-based monitoring, which measures predictable, predefined transactions from a steady-state client--such measurements help ensure the web site or enterprise application is up and available. The combination of agent-based and agentless monitoring offers the best of both worlds because IT practitioners have total visibility of the infrastructure to see when slowdowns occur. As a result, they respond to problems faster and prevent them from impacting the business. user experience of external web users as well as communication between application tiers without the need to modify application code. This provides a low-cost-of-ownership approach to monitoring your application, regardless of complexity, application architecture, etc.

What applications does the ClientVantage Agentless Monitoring solution support?

ClientVantage Agentless Monitoring targets web-based applications and their supporting middleware and databases, providing an overview of end-user experience, supplemented by analysis of the network and web server impact on transaction performance. The software highlights the most widely used web pages to help with the prioritization of problem resolution efforts.

Why should I choose a ClientVantage Agentless Monitoring solution?

1. Insightful visibility ClientVantage Agentless Monitoring shows you all users, all applications and transactions, all the time for internal and remote workers, business partners and customers. 2. No network overhead Because of its passive nature, ClientVantage Agentless Monitoring introduces no additional load to the application infrastructure. 3. Low administration The ClientVantage Agentless Monitoring solution passively collects data from a switch port or tap in your data center using an Agentless Monitoring Device (AMD). The AMD allows you to monitor the endThe Vantage Analysis Server provides flexible, interactive reports that show multiple dimensions of performance and diagnostics in a single view.

Monitoring between server tiers provides response times for database and middleware transactions. In a Citrix environment, agentless monitoring will tie these back-end performance measurements to the specific end user who initiated the transaction. For all other enterprise applications, ClientVantage Agentless Monitoring can be used as a gauge to monitor application performance using indicative metrics such as user wait time, server delay, network delay and transaction throughput.

What analysis options are currently available for the ClientVantage Agentless Monitoring solution?

ClientVantage Agentless is the market's leading solution to provide in-depth monitoring of critical applications, including Oracle Forms, Siebel and more. A partial list of agentless options are below:

How does ClientVantage communicate end-user experience measurements via the Agentless Monitoring solution?

To speed the understanding of performance bottlenecks, the Vantage Analysis Server (VAS) ties end-user service metrics on the URL Performance Overview to supporting network performance characteristics. Interactive reports provide near-real-time visibility of all user traffic to monitored web sites and enterprise applications. The VAS recognizes and counts all real web-site users and the

application servers' users, as well as reporting on usage, availability, network and server performance and errors for all web and non-web applications. The VAS provides:

How does the ClientVantage Agentless Monitoring solution support Citrix environments?

The Thin Client Analysis Module tags measurements taken on the path between the Citrix Presentation Server and the application server with actual Citrix user login names. It provides detailed user troubleshooting and activity tracking, by user name, for the applications that are served via Citrix. The module also provides resource utilization statistics of the Citrix Presentation Server (CPU, disk and memory load as well as the number of total and active terminal sessions), which enables instant correlation of the detected Citrix end-user application issue to the system resource shortage.

helps IT to focus on addressing those web-site problems that are most severe, as well as assigning the right person to the job. The AWDS provides:

What analysis does the ClientVantage Agentless Monitoring solution offer for web applications?

The VAS shows page load time, server time, HTTP response time, errors, redirect time, loss rate, RTT and realized bandwidth associated with web-page performance--in context of the named web-site users. The VAS reports data on five-minute intervals. For deeper analysis, the Vantage Advanced Web Diagnostics Server (AWDS) provides detailed insight about web page and business transaction performance down to each individual page hit using one-millisecond reporting granularity. Capabilities include diagnostics that help troubleshoot specific user problems and diagram web page and transaction delivery times, showing timings and errors for each individual web object and business transaction step. For rapid fault domain isolation, the AWDS builds an analytical model of web-site performance to find systemic problems that cause HTTP-based application performance degradation. It then quantifies the site-wide impact and severity in clear terms. This

What happens when my applications change? Do they require a lot of rework?

No. The AMD sees any new URLs, servers, applications and users, and automatically starts monitoring the new entities.

Are security risks associated with the ClientVantage Agentless Monitoring solution, and does it create a single point of failure?

No. The AMD is commonly attached to a listen-only port on a switch, or in some cases, a passive network tap. The actual user

traffic does not flow through the AMD. Confidential information content is not retained. Analysis of all the monitored traffic occurs in the memory of the AMD and only results of the analysis (measurements) are saved to a hard disk. Business-driven service delivery Compuware Vantage provides a real-time, comprehensive picture of service delivery, helping align IT services with business-critical objectives. Vantage includes:

·

Do I need ClientVantage AMDs at all my locations?

No. You only need to place AMDs at points where traffic of interest flows. For example, you would place an AMD in front of your webserver farm. It will monitor the traffic from all users and locations.

Business service management: linking critical business processes to IT services

How does the ClientVantage Agentless Monitoring solution provide end-to-end performance visibility for web applications?

The ClientVantage Agentless Monitoring solution allows you to quickly identify web pages suffering from long server-processing times and link to Vantage Analyzer, Compuware's deep-dive performance analysis solution for .NET and Java, for complete server-side visibility. With Vantage Analyzer, it's easy to drill down and see the performance of the thread responsible for serving a particular web page. Further object- and method-level analysis tells you exactly where the server spent time serving a page and which back-end systems and operations slowed down processing of the end user's request. The result? An end-to-end view of web transaction performance unmatched in the industry.
