Description

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

Connector ID: LinuxIfConfigNetwork

This connector is superseded by:

• CpqNICiLO
• LinuxIPNetwork
• MIB2Linux

Target

Typical platform: Any system

Operating system: Linux

Prerequisites

Leverages: Linux system commands (ifconfig)

Technology and protocols: System Commands

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 hwsagent account:

hwsagent ALL=(root) NOPASSWD: ethtool

Examples

hws HOSTNAME -t linux -f LinuxIfConfigNetwork --ssh -u USER --sudo-command-list ethtool

hosts:
- host:
    hostname: <HOSTNAME> # Change with actual host name
    type: linux
  selectedConnectors: [ LinuxIfConfigNetwork ] # Optional, to load only this connector
  ssh:
    username: <USERNAME> # Change with actual credentials
    password: <PASSWORD> # Encrypted using hws-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)
