Description

This connector discovers and monitors S.M.A.R.T.-enabled physical disk information through the smartd/smartctl utility under Linux.

This connector is superseded by:

• CpqSCSIDriveArray^[2]
• LSIsas2ircu^[3]
• SunHwMon^[4]
• CpqIDEDriveArray^[5]

Target

Typical platform: Any system with SmartMon

Operating system: Linux

Prerequisites

Leverages: SmartMon Tools

Technology and protocols: Command Lines

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

• /usr/sbin/smartctl
• /bin/dd

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 commands listed above.

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

metricshub ALL=(root) NOPASSWD: /usr/sbin/smartctl
metricshub ALL=(root) NOPASSWD: /bin/dd

Examples

metricshub HOSTNAME -t linux -c +SmartMonLinux --ssh -u USER --sudo-command-list /usr/sbin/smartctl,/bin/dd

resourceGroups:
  <RESOURCE_GROUP>:
    resources:
      <HOSTNAME-ID>:
        attributes:
          host.name: <HOSTNAME> # Change with actual host name
          host.type: linux
        selectConnectors: [ SmartMonLinux ] # Optional, to load only this connector
        protocols:
          ssh:
            username: <USERNAME> # Change with actual credentials
            password: <PASSWORD> # Encrypted using metricshub-encrypt
            useSudo: true
            useSudoCommands: [ "/usr/sbin/smartctl", "/bin/dd" ]

Connector Activation Criteria

The SmartMon Tools 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: /bin/ls /usr/sbin/smartd
  • Output contains: ^/usr/sbin/smartd$ (regex)
• The command below succeeds on the monitored host
  • Command: /bin/ls /usr/sbin/smartctl
  • Output contains: ^/usr/sbin/smartctl$ (regex)
• The command below succeeds on the monitored host
  • Command: /usr/sbin/smartd -c;/usr/sbin/smartd -q onecheck
  • Output contains: Device: .* opened (regex)
• The command below succeeds on the monitored host
  • Command: /usr/sbin/smartd -c;/usr/sbin/smartd -q onecheck
  • Output contains: Device: .* is SMART capable (regex)
