Path Trace App: Background Data Collection

§ Information Collected (The frequency is every polling interval)– Device, interface, link state– CDP, LLDP, IP device tracking DB– Wireless association– VLAN, STP– HSRP– OSPF, ISIS, EIGRP, BGP, static routes– More

§ Information Collected Using SNMP Traps– Wireless host discovery through SNMP traps– Wired host discovery through SNMP traps

APIC-EMNetwork

InformationBase

(NIB)

§ The Cisco® APIC-EM will periodically collect the device, host, and routing table information from the network elements

§ The collected information is stored in the APIC-EM network information base (NIB)

Note: the polling frequency is set to 30 minutes and is not configurable.

Example: Inventory IntegrationProblem: How to leverage APIC-EM discovery and inventory to feed service monitoring?

Real-World Example

Solution: Integrate APIC-EM REST APIs with existing Paessler / PRTG System:

1. Identify Relevant Service Domains

2. Run APIC-EM Discovery

3. Share APIC-EM Inventory via REST APIs and modular PowerShell Tool/Adapter

4. Correlate with EoX information viaapiconsole.cisco.com

5. Visualize and Share with IT and DevOps users via PRTG

Network

Example: Visualizing MulticastProblem: In a Hospital, Multicast is used for critical Medical Equipment as well as Patient Entertainment and Media – data privacy is a key concern. How to visualize the relevant multicast information?

Real-World Example

1)

Multicast Visualizer App

2)

Solution: Harvest information from the network and create custom, augmented displays

1) Collect relevant Topology, Inventory and Host information from APIC-EM

2) Augment with Multicast tree(s)

3) Use NeXt UI to for visual representation

4) Share with operational staff
