OpManager's WAN monitoring feature ensures high availability of WAN links across networks, providing comprehensive performance monitoring to meet Service Level Agreements (SLAs). Utilizing Cisco's IP-SLA technology, OpManager facilitates easy setup without requiring IPSLA expertise. It includes efficient data collection, proactive threshold settings, and Path Echo mode for precise troubleshooting.
OpManager's WAN monitoring also allows you to monitor your WAN links' availability, RTT, and traffic details. Furthermore, you can also visualize them in the form of reports and dashboards, helping you gather actionable insights.
OpManager primarily relies on Cisco's IP-SLA for monitoring the WAN and the prerequisite therefore is that the device should be a Cisco router and must have IPSLA agent enabled on it. Almost all the routers from Cisco are enabled with IP SLA agent and OpManager supports IOS version 12.3 and above. OpManager uses SNMP to query the Cisco routers for the links' performance data. IPSLA familiarity is not a prerequisite. You just need to tell OpManager which links you want to monitor. OpManager provides an intuitive configuration wizard to help you configure all the IPSLA parameters for monitoring the WAN health.
Using OpManager, you can now monitor the availability and latency of a WAN link / path. A WAN link mentioned here is the path between the router in your main office and the one in the branch office that you wish to monitor.
snmp-server host <OpManager server IP> traps <host community string> rtr
For instance, if the OpManager host IP Address is 192.168.18.128, and the community string is private, the command would be:
snmp-server host 192.168.18.128 traps private rtr
To edit any of the configuration details, go to the respective template, make the changes and save the details. When you create a new monitor, the updated values take effect. When the configuration is complete, the router starts collecting the data at the specified frequency i.e. 60 seconds (default value). OpManager updates this statistics (collected data) every hour and the reports are generated after one hour of configuration.
