The WAN being an expensive part of the corporate network, one needs to be kept informed of any outage⁄ unscrupulous usage⁄ intermittent connectivity. This is where establishing a proper monitoring practice for WAN environment is important. WAN management involves monitoring the WAN for health, performance and availability. It is essential for organizations, especially for the ones that depend on WANs for their crucial operations.
Regular monitoring ensures the WAN performs efficiently, without any performance bottlenecks. This largely helps reduce network downtime, which is an even costlier game when it comes to wide area networks. This way, it helps maintain reliability in the network where potential issues are addressed well before they impact the network largely. Effective WAN management also ensures proper planning for future network growth, with the ability to accommodate increased traffic. For organizations that are spread over geographies, it is essential to monitor those WAN connections as well for availability and performance.
ManagEngine OpManager is a versatile network monitoring software that helps manage all the network devices - routers, switches, firewalls, load balancers, wireless LAN controllers, servers, VMs, printers, and storage devices, from a single console. OpManager leverages Cisco IPSLA technology to help you visualize your WAN links and troubleshoot WAN outages and performance issues, even over your ISP infrastructure.
Upgrading your WAN pipes is neither a permanent, nor a cheap solution to improving application performance across the WAN. OpManager’s WAN RTT (Round–Trip–Time) monitor provides details on WAN link latency, bandwidth utilization, Round–Trip–Time and other performance factors for you to completely diagnose and resolve poor WAN performance before you can think of upgrading WAN bandwidth capacity.
OpManager brings WAN link availability and performance information to the fore with the help of an intuitive network dashboard. The WAN RTT dashboard’s business views graphically represent the various links over geographical maps. Each link’s information on status and latest alarms generated are presented to give a quick bird's eye view of entire WAN link health.
Sometimes terrible network quality may be just as worse as no connectivity at all. A round trip time (WAN RTT) of 200ms across a link where the expected round trip time is 60ms is definitely unacceptable. OpManager allows you to set custom thresholds based on agreed service levels (SLAs) with Service Providers. The WAN RTT dashboard presents Top Paths by RTT Threshold Violation and Top Paths by RTT (Round Trip Time) to help WAN administrators know which WAN links require immediate attention.
OpManager doesn’t merely identify network delay or outage, it also helps you to drill down to the hop level displaying the various paths of communication between the source and destination and the round trip time across each underlying link. OpManager simplifies WAN Latency monitoring by performing an automatic traceroute on the WAN links to present hop–wise latency count and information about packet loss monitoring metrics across the entire circuit in a single graph.
OpManager provides informative reports that can help in capacity planning and other WAN investment decisions.
The WAN specific reports available through OpManager include:
