Application Analysis Troubleshooting & Problem Identification

Example #1 – Real-Time Troubleshooting

Situation: A large Law firm has been experiencing network slowdowns during peak usage times.

Solution: Determine who or what is causing heightened levels of network activity at peak times.

Step 1: Check Bandwidth Utilization, which shows higher than expected utilization levels

Example #1 – Real-Time Troubleshooting

Step 2: Review Top Talkers to determine active Backup Sessions during the afternoon are consuming network resources

Example #1 – Real-Time Troubleshooting

Observer provides real-time identification of network issues for faster troubleshooting.

Example #1 – Recap

Situation: A large Law firm has been experiencing network slowdowns during peak usage times late in the afternoon.

Solution: Determine who or what is causing heightened levels of network activity at peak times.

Result: By reviewing Observer’s Real-Time Statistics, network administrators were able to quickly determined that backups were running during work hours and promptly reconfigured the backup schedule.

Example #2 – Proactive Discovery

Situation: Network Operations for a large Community College is concerned with Peer to Peer client usage and virus activity on their wired and wireless networks.

Solution: Monitor both the Wired and Wireless environment with Observer’s Triggers and Alarms.

Step 1: Configure Triggers & Alarms for multiple probes from a single display

Example #2 – Proactive Discovery

Step 2: Define alarms on each probe, customizing Observer for each network segment

Example #2 – Proactive Discovery

Step 3: Set Variable Alarm Thresholds to help eliminate false positives

Example #2 – Proactive Discovery

Step 4: Define the appropriate action(s) for each alarm configured

Example #2 – Proactive Discovery

Observer provides proactive discovery and notification of rogue elements.

Example #2 – Recap

Situation: Network Operations for a large Community College is concerned with Peer to Peer client usage and virus activity on their wired and wireless networks.

Solution: Monitor both the Wired and Wireless environment with Observer’s Triggers and Alarms.

Result: Using Observer’s Proactive Network Monitoring tools, the network operations team quickly identified a virus outbreak and prohibited illegal usage.

Example #3 – Application Analysis Situation: An large accounting firm has the need to track and

identify application metrics, such as response time, as well as troubleshoot application connections.

Solution: Application Analysis, paired with Connection Dynamics, offers an in-depth view of application response time, statistics, and conversation flows.

Step 1: Monitor Application Level Response Time

Example #3 – Application Analysis

Step 2: Examine Application Specific Statistics

Example #3 – Application Analysis

Step 3: Review Graphical Application Flow Detail

Example #3 – Application Analysis

Observer allows you the ability to quickly differentiate

between Network and Application Performance

Example #3 – Application Analysis

Situation: An large accounting firm has the need to track and identify application metrics, such as response time, as well as troubleshoot application connections.

Solution: Application Analysis, paired with Connection Dynamics, offers an in-depth view of application response time, statistics, and conversation flows.

Result: Isolate and identify application delay on the network, to put the responsibility on the proper group, and offer faster problem resolution for users.

Example #4 – Forensic Analysis Situation: A major retail company has been tasked with

researching the violations of their acceptable use policies by a former employee.

Solution: The GigaStor appliance, featuring a time-based navigation interface, allows for complete write-to-disk at Gigabit line speed, to ensure all necessary data is captured and stored

Step 1: Identify the timeframe of interest using the GigaStor Time Analysis Interface

Example #4 – Forensic Analysis

Step 2: Determine the stations, conversations, or ports of interest from the specified timeframe

Example #4 – Forensic Analysis

Step 3: Complex filters can be created automatically, and will be run against the specified timeframe

Example #4 – Forensic Analysis

Step 4: Complete reconstruction capabilities allow an administrator to reassemble original documents such as emails, IM conversations, web pages, and even VoIP calls

Example #4 – Forensic Analysis

Example #4 – Forensic Analysis

Situation: A major retail company has been tasked with researching the violations of their acceptable use policies by a former employee.

Solution: The GigaStor appliance, featuring a time-based navigation interface, allows for complete write-to-disk at Gigabitline speed, to ensure all necessary data is captured and stored.

Result: Proactive monitoring allows the organization to have relevant information available without the need to recreate an issue, or, in this case, not have the ability to verify a potential conflict with their acceptable use policy.
