Ethernet Traffic (EPT1)
This probe measures the amount of traffic (bytes) sent and received from the network via the ethernet (LAN) interface.
Version 1.0 - General deployment
- Feature: Initial value
Resource configuration interface
- Interface: name of the interface to be monitored. This defaults to
eth0 which is normally the only useful value.
This probe generates a graph with following performance metrics:
- in: the number of bits per second received from the network, averaged over 5 minutes.
- out: the number of bits per second sent to the network, averaged over 5 minutes.
This probe can report following alarm states:
- CRITICAL: the Ethernet interface is down.
A CRITICAL alarm may be caused by:
- Ethernet cable disconnected or malfunction.
- Misconfiguration or malfunction of the connected Ethernet switch.
- no Internet connection
- no remote console access
- service down (e.g. telephony, application)
Abnormal high network bandwidth utilization:
- Degraded service like bad audio quality or slow application
In case of a CRITICAL alarm:
- Check cabling and switch
- Check link up indicator LED
In case of an abnormal high network bandwidth utilization following actions may be performed:
- Capture network traffic to see what is using the most bandwidth.
