Monitor server interface bandwidth usage by SNMP ...

[xpertech]

What's the most popular and easy plugin on monitoring server interface bandwidth usage by SNMP only?

In Nagios XI, there is a wizard called the Network Switch / Router Wizard which is used to monitor Network Ports for Bandwidth and for Up / Down Status.

The following links has a video on using the Wizard and some details on how the devices are monitored.

what I need is for serve network interface bandwidth usage, not for switch/router.

The wizard will work with Servers as well. It is not limited to Switches or Routers.
I used it to monitor various Windows and Linux systems.

Is it possible to freely edit the bandwidth value for warning & critical and then save as a template using for next time, rather than edit it every time when create a new monitor?

The monitored ports and threshold settings for the interfaces are unique to each device and when saving a template, it does not store the unique settings and it is not possible to do that.

When you do run the wizard, on the first screen, you can set the Default Port Speed. This will set it to all of the ports but is should get most of the ports set correctly in the Wizard.

FYI, it the port is disconnected, the wizard cannot determine the speed correctly all of the time so settings the Default Port Speed helps set the correct speed for the disconnected ports.
