This document covers a free training session on monitoring network performance using OpManager, focusing on various aspects such as hardware sensors, SNMP monitors, WAN and VoIP links, and creating custom SNMP monitors. It provides details on monitoring specific devices like routers, switches, and firewalls, as well as performance analytics such as latency, jitter, and bandwidth usage. Additionally, it discusses configuring network maps and customizing dashboards for efficient network management.

5. Agenda
 Monitoring network performance
 Monitoring hardware sensor
 Creating custom SNMP monitor
 Monitoring WAN and VOIP links
 Network maps

6. Performance monitors Protocol
CPU, memory, temperature, etc. SNMP
Cisco UCS UCS API
Network devices/ other infrastructure devices such as
printer, UPS, etc.
SNMP
WAN latency check IPSLA (Cisco devices only)
VOIP latency check, mos, jitter, etc. IPSLA (Cisco devices only)
*Configure SNMP on the network devices

7. Monitoring Router performanceo CPU/memory usage
o Temperature, etc.
o Setting up threshold for the performance monitors
Monitoring network performance
Monitoring Switch performance
o CPU/memory usage
o Back plane utilization, etc
Monitoring Firewall performance
o CPU/memory usage
o Active session count, etc
Monitoring Printer performance
o Paper jam, low paper or no paper
o Low toner or no toner, etc
Monitoring Router performance
o CPU/memory usage
o Temperature, etc.
o Setting up threshold for the performance monitors

8. Monitoring bandwidth/ traffic
Interface performance counters
• Bandwidth usage
• Errors/discards
• Received and transmitted traffic
• Total bytes received
• Total bytes transferred
• Real time interface monitors
*SNMP based
monitoring

9. 1. Enable or disable monitoring for
specific interface type
2. Configuring monitoring interval for the
interface type
3. Configuring thresholds for utilization,
errors and discards
4. Enable or disable interface status

12. Creating a custom SNMP monitor
Prerequisites
• SNMP-enabled device
• Vendor MIBs >> OpManagermibs
Mibs
• What is a mib file?
• How to obtain the mib file?
• Uploading the mib files in OpManager
Examples
• Creating a custom monitor
• Performing mathematical operations on OIDs using expressions
(.1.3.6.1.4.1.9.9.48.1.1.1.5.1*100) / (.1.3.6.1.4.1.9.9.48.1.1.1.5.1+.1.3.6.1.4.1.9.9.48.1.1.1.6.1)
• Functional expressions
(Celsius to Fahrenheit, Kilobyte to Megabyte, Average of column values, Sum of column values, etc)
• Monitor instances

13. WWAN
Development Center HeadquartersService Provider

14. • Identify the network paths with high round trip time
• Identify where the outage happened by viewing the hop-
wise latency graph
• Collect the IPSLA traps for events such as connection
loss, threshold violation for RTT, average payload,
timeout, etc
Monitoring WAN performance

15. Prerequisites
• A Cisco router with an IPSLA agent enabled
• iOS version must be 12.3 or later
• SNMP read and write community configured on the
device
• Configure the device to send traps to OpManager
server
How to add?
• Go to Inventory > Select IPSLA
• Select WAN > Click plus icon at the top of the page
• Add the details of the source and destination IP
Adding WAN monitor

16. • Jitter: The variation in delay between arriving packets
• Latency: The time taken for the voice packets to reach the
destination
• Packet loss: Data lost during transmission
• Mean opinion score (MOS): The standard for measuring
codecs and is rated on a scale of 1 to 5
VOIP performance monitoring

17. Network maps : #1 Business views
• Group devices based on geographical
site or department or business service
• Add link between devices and monitor
the link connectivity
• Add shortcuts in a business view for
branch offices
• Restrict user access based on
business view groups

18. Network maps : #2 Maps
Google Maps API
is now charged
Zoho Maps Free

19. Network maps : #3 Building racks & 3D floor view
Rack View 3D Floor View

20. Customizing dashboard
Network management : Dashboards and
widgets
1. Total network traffic across all servers
2. Devices which are using high % of their CPU and Memory
3. All active alarms
4. Downtime report for all devices and services
5. IT summary
