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.
Example #1 – Real-Time Troubleshooting
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 – 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.
Observer provides real-time identification of network
issues for faster troubleshooting.
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.
Example #2 – Proactive Discovery
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 – 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.
Observer provides proactive discovery and
notification of rogue elements.
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.
Example #3 – Application Analysis
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

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.
Observer allows you the ability to quickly differentiate
between Network and Application Performance
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
Example #4 – Forensic Analysis
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

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.

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.
