SmartMon Tools Enterprise

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This connector is superseded by:

hardware[6] linux[7] storage[8]

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

CLI

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

  <RESOURCE_GROUP>:
    resources:

          host.name: <HOSTNAME> # Change with actual host name
          host.type: linux
        connectors: [ +SmartMonLinux ] # Optional, to load only this connector
        protocols:

            password: <PASSWORD> # Encrypted using metricshub-encrypt

            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)
