Bandwidth Monitoring

Nagios provides complete bandwidth monitoring of switches and Routers via SNMP. Switches and routers can be monitored via SNMP v1, 2c, or 3 and deliver bandwidth utilization for both inbound and outbound traffic. Thousands of different network devices are enabled by default for this type of monitoring. Nagios allows you to run the switch or router monitoring wizard and setup to monitor bandwidth on the device can be done in just minutes.

Implementing effective monitoring of bandwidth with Nagios offers the following benefits:

  • Easily find over utilized ports
  • Discover possible network abusers
  • Ability to track per-port bandwidth utilization and errors
  • Fast detection of network outages and protocol failures
