Cisco, Devices, IT360, management, network, OpManager, SNMP
IT360 uses opmanager module for the network management service. This tap when clicked will show a window that gives a very comprehensive view of the whole network. From the figure below, it shows the various elements. First it will show the devices (It supports many other devices, a list can be seen from their website). A map can be uploaded to show a geographical representation of the devices. Event Summary will show all the monitors applied and if anything has been triggered. in our case we have plenty of violations (mostly link over utilization). it will show the top 10 for CPU utilization, Memory Utilization, Interface Traffic, and Bandwidth. These were the monitors configured in the start. If more monitors were configured, we expect to see them in this window as well.
Clicking on any device will give a general view of the device. when the SNMP configured properly, it managed to show the device name, ip address, vendor, type, and general description. on the right: availability, response time, packet loss, CPU utilization, Memory Utilization, and Backplane utilization. More monitors can be added from the action tap. Scrolling down, we see the monitors, notifications, and interface. I picked the interfaces and then we can see a detailed view of all the interfaces, from name, send and received traffic, errors and a real time monitor. Real time monitor can be configured to update per second for 5 mins. the interfaces will show green (up/up, or administratively down), Red (up/down) and orange for any violation. all this can be seen from the figure Below
Going to the interface. it will show interface details, utilization graphs. day’s traffic that can be modified to show up to a month. Errors and Discards can be seen as well. It will also show packets per day, and bytes per second. The one issue I found it to be very strange. The Real time traffic showing me traffic exceeding 1Gbps, where the link is only 1Gbps.
In the case more monitors are needed to be added. here a brief list of all the possible built in monitors.
The OpManager and IT360 do provide a good solution for the Network services.
