Description

This connector enables the monitoring of active network cards on all Linux systems using ifconfig command.

This connector is superseded by:

• MIB2Linux^[2]
• LinuxIPNetwork^[3]

hardware^[4] linux^[5]

Source^[6]

Target

Typical platform: Any system

Operating system: Linux

Prerequisites

Leverages: Linux system commands (ifconfig)

Technology and protocols: Command Lines

This connector requires advanced privileges on the managed host for the command below:

• ethtool

This connector therefore needs to run as root or you need to configure a privilege-escalation mechanism like sudo on the managed host to allow the monitoring account to run the command listed above.

Sample of /etc/sudoers to allow the above command to be run as root by the metricshub account:

metricshub ALL=(root) NOPASSWD: ethtool

Examples

metricshub HOSTNAME -t linux -c +LinuxIfConfigNetwork --ssh -u USER --sudo-command-list ethtool

resourceGroups:
  <RESOURCE_GROUP>:
    resources:
      <HOSTNAME-ID>:
        attributes:
          host.name: <HOSTNAME> # Change with actual host name
          host.type: linux
        connectors: [ +LinuxIfConfigNetwork ] # Optional, to load only this connector
        protocols:
          ssh:
            username: <USERNAME> # Change with actual credentials
            password: <PASSWORD> # Encrypted using metricshub-encrypt
            useSudo: true
            useSudoCommands: [ "ethtool" ]

Connector Activation Criteria

The Linux - Network (ifconfig) connector will be automatically activated, and its status will be reported as OK if all the below criteria are met:

• Operating System is Linux
• The command below succeeds on the monitored host
  • Command: /sbin/ifconfig -a
  • Output contains: LOOPBACK (regex)
