Monitoring network performance;
Network maps

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

7. 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

8. 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

9. 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

10. 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 polling
Interface templates

11. Interface groups
1. Creating interface groups based on
site, department, customers, etc
2. Threshold settings based on custom
interface groups
3. Dashboard for groups and sub groups
4. Filters based on Interface groups in
widgets
5. Filters based on Interface groups in
reports

12. Monitoring hardware sensor
Power VoltageTemperature Battery Disk Array Data Fan
Supported vendor's
Sensor categories

13. Setting up hardware monitoring
Go to Settings > System Settings > Hardware monitor
o Enable Hardware monitor
o Suppress Hardware Alarms
o Monitor interval
o Hardware health report

14. 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

15. WAN
Development Center HeadquartersService Provider

16. • 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

17. 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 Network > Select IPSLA
• Select WAN Monitor > Click plus icon at the top of the page
• Add the details of the source and destination IP
Adding WAN monitor

18. • 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

19. 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

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

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

22. 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
