Typical hourly cost of downtime by industry (in U.S. dollars):
• Brokerage service --- 6.48 million• Energy --------------- 2.8 million• Telecom -------------- 2.0 million• Manufacturing ------- 1.6 million• Retail ----------------- 1.1 million• Healthcare ----------- 636,000 • Media ----------------- 90,000
SMB loss based on IT failure is about $55,000 per year in revenueMid-sized companies lose about $91,000 per year in revenueLarge companies lose about $1 Million per year in revenue

10 Steps to Avoid Network Monitoring Nightmares
STEP #1: Map out your architecture and ensure its accuracy.
What type of devices are in your network?
How many of each device do you have?
Where is each device physically located?
How do devices connect to the rest of the network?
![Page 10: 10 Steps to Avoid Network Monitoring Nightmares](https://reader035.fdocuments.us/reader035/viewer/2022070515/587b5bd91a28ab38258b4a65/html5/thumbnails/10.jpg)
10 Steps to Avoid Network Monitoring Nightmares
STEP #2: Determine what information is most critical to monitor.
Which devices—if they failed—would cause major operational bottlenecks?
Monitor the metrics that would signal when those devices go off the grid.
![Page 11: 10 Steps to Avoid Network Monitoring Nightmares](https://reader035.fdocuments.us/reader035/viewer/2022070515/587b5bd91a28ab38258b4a65/html5/thumbnails/11.jpg)
10 Steps to Avoid Network Monitoring Nightmares
STEP #3: Configure exception-based notifications with a clear escalation plan.
Don’t let false positives fill your inbox.
Set up exception-based notifications to help you solve real problems quickly.
![Page 12: 10 Steps to Avoid Network Monitoring Nightmares](https://reader035.fdocuments.us/reader035/viewer/2022070515/587b5bd91a28ab38258b4a65/html5/thumbnails/12.jpg)
10 Steps to Avoid Network Monitoring Nightmares
STEP #4: Identify and monitor networkperformance baselines.
Monitoring baselines helps you: • Know what normal device
performance looks like• Be aware of scheduled exceptions to
normal traffic levels (e.g. nightly backups)
• Set appropriate traffic thresholds
![Page 13: 10 Steps to Avoid Network Monitoring Nightmares](https://reader035.fdocuments.us/reader035/viewer/2022070515/587b5bd91a28ab38258b4a65/html5/thumbnails/13.jpg)
10 Steps to Avoid Network Monitoring Nightmares
STEP #5:Configure SNMP on network devices.
Why? So you can monitor metrics beyond simply “up” or “down” status.
EXPERT TIP: Use SNMPv3 to ensure network security.
![Page 14: 10 Steps to Avoid Network Monitoring Nightmares](https://reader035.fdocuments.us/reader035/viewer/2022070515/587b5bd91a28ab38258b4a65/html5/thumbnails/14.jpg)
10 Steps to Avoid Network Monitoring Nightmares
STEP #6: Make upgrades to your core hardware to support performance monitoring
protocols.
Replace outdated hardware (instead of wasting your time optimizing it).
EXPERT TIP: Make sure core network devices support modern performance monitoring protocols.

STEP #7: Use NetFlow to capture and monitor bandwidth utilization on routers and switches.
Analyzing flows data can help you:
• Identify the source of bottlenecks
• Plan how much bandwidth capacity you’ll need

10 Steps to Avoid Network Monitoring Nightmares
STEP #8: Use protocols to support Windows and Linux servers.
Use these protocols to ensure secure connections on remote machines:
• WMI (Windows)
• PowerShell (Windows)
• SSH (Linux)

10 Steps to Avoid Network Monitoring Nightmares
STEP #9: Keep probe and MIB architecture updated to ensure monitoring of all
devices.
Networks with a variety of standard and non-standard equipment require probe and MIB architecture that is constantly up-to-date.
EXPERT TIPS: • Use industry SNMP MIBS to
capture performance data for standard network components.
• Use vendor-provided MIBs to monitor non-standard devices

10 Steps to Avoid Network Monitoring Nightmares
STEP #10: Implement continuous monitoring (24/7).
Ongoing monitoring helps ensure healthy network operations and 24/7 access to your products and services.
EXPERT TIP: Mobile capabilities make it easy to keep tabs on real-time network performance from anywhere.
