Application Performance Monitoring

Monitoring application performance from a high level is important, but without packet-level analysis it's impossible to actually resolve the issue. Unlike traditional reporting tools, Observer Reporting Server's (ORS) version 13 troubleshooting enhancements make it easy for you to monitor performance trends and diagnose the source of delay in one solution.

Speed Root-Cause Analysis with Enhanced GigaStor

Regardless of the innumerable tasks required of network engineers, their primary purpose is to ensure the prompt delivery of applications to users. As a part of version 13 upgrades, we've enhanced GigaStorâ„¢ to speed the troubleshooting process. The improvements make it easier to sift through terabytes of data, perform analysis, isolate problems, and find their sources.

Top 5 Observer 13 Features

VIAVI Solutions has a history of developing features around customer requests. For example, the introduction of Observer Reporting Server (ORS) was driven by customer need to aggregate Observer views. Upon using ORS, many asked for greater troubleshooting capabilities. As shown below, VIAVI Solutions has met those customer requests by adding real-time analysis in ORS.

Are You Prepared for Unified Communications?

The migration of organizations from gigabit to 10 Gigabit Ethernet (10 Gb) networks is often driven by unified communications initiatives that push traditional communication functions onto the network. Unified communications (UC) programs involve a combination of network-driven communication tools including VoIP, Web conferencing, online collaboration, instant messaging (IM), email, voicemail, and videoconferencing.

10 Gb Adoption Trends & Obstacles

With nearly one-quarter of global organizations implementing 10 Gigabit Ethernet (10 Gb) by the end of 2008, it is safe to say that a steady migration to 10 Gb is underway. This trend is currently driven by larger organizations, but with the price of 10 Gb infrastructure falling adoption is becoming more widespread. This article explores adoption trends and the hidden costs of moving to 10 Gb.

Application Analysis and Probe Placement

Ensuring timely access to business-critical application servers is what justifies having a network (and an IT staff) in the first place. Effectively monitoring applications means measuring how well key components of the IT infrastructure are performing over time and identifying problems before they affect your business.
