Description

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

Connector file name: MS_HW_SmartMonLinux.hdf

This connector is superseded by:

• MS_HW_SunHwMon.hdf
• MS_HW_CpqSCSIDriveArray.hdf
• MS_HW_LSIsas2ircu.hdf
• MS_HW_CpqIDEDriveArray.hdf

Target

Typical platform: Any system with SmartMon

Operating system: Linux

Prerequisites

Leverages: SmartMon Tools

Technology and protocols: System Commands

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

• /bin/dd
• /usr/sbin/smartctl

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 patrol account:

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

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)
