What is Application Availability ?

Application availability is the inclination of an application to handle end user requests and to return timely and accurate responses. As business becomes increasingly dependent on information technology, application availability is a universal concern for every business, in every IT infrastructure. The need for system availability extends across all components of a network. But nowhere the availability of a system is more obvious to users or more analytical of the competence of IT managers than at the application level. The function of application availability is to meet business needs. For today’s business-critical applications, enterprises require robust, proven solutions for application performance and IT monitoring. They must be confident that they are protected, not only against physical server failures, but also from outages that affect individual virtual servers and the applications running inside them.

Web-based business applications have become an essential component of every business. These applications are mission-critical, executing various organizational business processes. Whether it is a pure Web-based multi-tier application or a front end to an existing ERP or legacy system, the availability of the application and the content of transaction output need to be monitored all time, to ensure the reliable and correct operation of the business processes. Tevron’s CitraTest APM provides a way to quickly, efficiently, and discreetly monitor the application availability, reliability, and application performance as well as capture the hard-to-get URL-to-SQL application metrics. It presents these important metrics in a manner that enables hard communication and rapid proactive or reactive detection, correction, and verification throughout the application lifecycle. By using CitraTest APM, the availability of the application has increased and improved by a few percentage points so that thousand man-hours of down-time is saved and hence results in millions of dollars in improved efficiency throughout the organization.

Through the use of Tevron’s CitraTest APM, IT Administrators can better monitor access and performance and cost effectively run IT in alignment with company objectives. As a result, Business Managers can boost up IT Performance that helps achieve the business goals through increased IT efficiency and profitability.

Tevron's APM solutions address the critical IT issues identified in Aberdeen's recent Application Performance Management Research

Nashua, New Hampshire, November 20, 2008 - Tevron’s APM solutions directly address the key critical IT needs identified in Aberdeen’s Applications Performance Management Research. Some of the key findings from this Aberdeen research include:

• Issues with application performance can impact overall revenues by up to 9%
• Rolling out new enterprise applications is the top IT initiative for the next 12 months
• Only 44% of organizations are satisfied with performance of business-critical applications
• Inability to prevent network and application performance issues before they impact end-users is the top challenge around network and application performance management
• Inability to test applications in pre-production, lack of tools for visibility into network and application performance, and lack of visibility into quality of end-user experience are the top concerns for the next 12 months
• Server and desktop virtualization projects and increased amount of digital content are the top 2 technology drivers for investing in new network and application performance management solutions

Transaction Monitoring Solutions for End Users

Any business enterprise needs transaction monitoring solutions. Application measuring, monitoring service levels and system health is of great importance for any organization. Most of the monitoring tools are designed to monitor comprehensive infrastructures and devices. Major problems of application performance are reported to the IT team by the end users experience. IT service management needs a solution that can proactively see these problems and help to solve them before the end-user gets impacted.

These “Real User Transactions” are securely executed in the Windows service space to actively measure the End-To-End User Experience. Through the deployment of Tevron’s APM solutions, every application across the enterprise can be accurately measured and actively monitored allowing for the enforcement of all SLAs. By providing the ability to perform “Secure-Parallel Monitoring”, a single monitoring machine can remain in a “logged off” state from a specific point of presence in the enterprise to execute and measure real-world user transactions concurrently ensuring security and further expanding the overall coverage bandwidth. CitraTest APM can efficiently help for transaction monitoring that can uncover errors, misuse, and identify key process risks based on transactions, controls and business. It can correct unexpected results at an early stage.

Using Tevron’s CitraTest APM makes it easy to monitor and measure end user experience. Its robust transaction monitoring feature can track and alert on application and service health, notifying before the problem can impact. By monitoring the end user response time, it can perform customer analytics and system health check from the server’s outer boundaries.

CitraTest APM is easy to use and integrates with other tools to provide superior transaction monitoring and application monitoring solution support platform for customizable web based reports and real time dashboards.

How to deal with the Key Challenges to Citrix Monitoring?

When monitoring any Citrix hosted application, the key challenge is to identify how any application is responding at any point across the enterprise based on the real user perspective. How do the end-users see application perform from their client access points? It’s important to know whether every location delivers similar performance.

Tevron’s CitraTest® APM solution is an all encompassing APM solution that addresses the needs of Citrix monitoring, End to End Response Time, Availability Monitoring, and SLA Enforcement across any organization. All measurements are based on the Real User Experience and nothing is installed on the Citrix application server.

Tevron’s CitraTest® APM can replicate every user transaction and execute it periodically from every client access point. All these real user measurements are then collected and analyzed. Application performance thresholds can be set and alerts can be generated when those thresholds are exceeded. This approach gives IT organizations the ability to proactively and continuously manage every application across the enterprise, preventing system down time and saving time and money.

• Unique Benefits Delivered
  
  Tevron’s CitraTest® APM supports every application across the enterprise with one powerful solution. Any activity a Real User performs can be exactly replicated to be used as a measuring stick. Because the production environment is not changed in any way and all measurements are taken from the client perspective, the benchmarks and application availability metrics are exactly what the real users see and experience. This critical information can then be used to find and correct application performance issues before end users find them.

• Open Architecture

Tevron’s core monitoring technology is based on an open architecture allowing IT organizations to integrate this solution seamlessly into their current methodologies. All performance results can be shared with any application. In addition, full support for Microsoft MOM 2005 is also offered along with support for several other Event Management and Performance Systems.


• Ease of Use and Deployment

Tevron’s CitraTest® APM can easily be deployed across the enterprise to actively monitor all enterprise applications. There is no limit to the number of applications or the number of locations that can be monitored. This solution is easy to use and the user experience scripts are easy to create and deploy. All results are stored in a central database that is accessible via a Web based console. SLA reports based on application, location, and user type are automatically generated on a daily basis for IT Managers to analyze.
