Network Monitoring - How ManageEngine OpManager fits in
ManageEngine OpManager has a single big advantage of either loosely or tightly integrating with the other applications in the ManageEngine Suite. Built on a robust platform, OpManager addresses all the key requirements an administrator or an IT Manager looks for in a network monitoring solution. Let us quickly look at how each of the above functionality is addressed in ManageEngine OpManager:
Automatic Discovery
OpManager Network Monitoring provides various options as part of its automatic discovery feature. Further, the devices are automatically classified based on the category into Routers, Switches, Servers etc. OpManager relies on the standard SNMP ⁄ ICMP pings to perform deep discovery. The discovery options include the following:
IP Range–based Discovery - The option to discover by specifying a range is useful when there is a need to manage devices just within that range and proves less costly as opposed to scanning a complete network. When a new device is plugged into the network, the application to Monitor Network must be able to only that specific device.
CIDR Discovery - CIDR is Classless Inter Domain Routing, an IP addressing scheme that replaces the system based on classes A,B, and C.
File–based Discovery - This option is useful when an administrator has to discover a random set of devices across networks. Discovery must be initiated for a list containing the host–names or the IP addresses of the devices to be managed.
On–demand Discovery - When a new device is plugged into the network, the application to Monitor Network must be able discover only that specific device.
Monitoring almost every resource on the network
OpManager Network Monitoring supports industry standard monitoring protocols that include SNMP, WMI, Telnet, and SSH, besides allowing custom scripting. It monitors almost every network resource and reports the performance.
Availability and Up time monitoring - A quick, safe option to determine the performance of a network and its resources is to simply check its availability. Something as simple as a ping determines if a device is up or down. Checking for availability is often the start point from where an administrator can drill down to the root cause. Proactive Network Monitoring for availability and uptime ensures that you have a plan B in place if the server or link cannot be made functional in a given time.
System Resources monitoring - Any device is rendered unavailable if the hardware shows poor performance. An overloaded server may have its CPU and Memory eaten up by the applications hosted on it and make the server useless. By watching the performance of the resources, the system administrators can effect capacity planning, distribute the resources, or upgrade the resources much before a problem is encountered.
Bandwidth monitoring - Any business relies heavily on the WAN, which is an indispensable and costly side of an enterprise network. A network administrator must be wary of the impending outages and equip accordingly so that the business is not affected. Keeping a tab on the WAN link latency, bandwidth utilization, the round–trip–time (RTT), etc enables the administrator to avoid serious outages, and also aids in capacity planning.
Infrastructure Maps and Business Views
The discovered devices are grouped by category for easy Network Monitoring. Besides, OpManager allows you to create your own views to group the devices logically and manage them from one place. This option helps you manage the devices under each geographical location and assign authorized access to the business views.
