Ethernet Traffic (EPT1)

Description

This probe measures the amount of traffic (bytes) sent and received from the network via the ethernet (LAN) interface.

Release notes

Resource configuration interface

Resource parameters

• Interface: name of the interface to be monitored. This defaults to eth0 which is normally the only useful value.

Performance graphs

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.

Alarms

This probe can report following alarm states:

• CRITICAL: the Ethernet interface is down.

Possible causes

A CRITICAL alarm may be caused by:

• Ethernet cable disconnected or malfunction.
• Misconfiguration or malfunction of the connected Ethernet switch.

Possible consequences

Critical alarm:

• 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

Possible actions

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.
  • SOP Shell > Diagnostics > Network > Capture traffic by host
