HP-UX - Disks

Description

This connector provides hardware SCSI disks status information on HP-UX systems. Requires root privileges.

hardware hp-ux hpe

Enterprise Connector

This connector requires the Enterprise edition of MetricsHub.

Superseded Connector

This connector is superseded by:

• HPUXWBEM

Target

Typical platforms: HPE Alletra 9000, HPE Integrity, HPE SuperDome, HP-UX

Operating system: HP-UX

Prerequisites

Leverages: HP-UX system commands (pvdisplay, ioscan, etc.)

Technology and protocols: Commands

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

• /usr/sbin/diskinfo

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: /usr/sbin/diskinfo

Examples

CLI

metricshub HOSTNAME -t linux -c +HPUXDisk --ssh -u USER --sudo-command-list /usr/sbin/diskinfo

metricshub.yaml

resourceGroups:
  <RESOURCE_GROUP>:
    resources:
      <HOSTNAME-ID>:
        attributes:
          host.name: <HOSTNAME> # Change with actual host name
          host.type: linux
        connectors: [ +HPUXDisk ] # Optional, to load only this connector
        protocols:

            useSudoCommands: [ "/usr/sbin/diskinfo" ]

Connector Activation Criteria

The HP-UX - Disks connector will be automatically activated, and its status will be reported as OK if all the below criteria are met:

• The device type must be one of: HP
• The command below succeeds on the monitored host:
  • Command: if /bin/test ! -f /usr/bin/stm ; then /bin/echo "NO STM"; fi
  • Output contains: ^NO STM$ (regex)
• The command below succeeds on the monitored host:
  • Command: FIRSTRAWDEVICE=/bin/ls /dev/rdsk|/bin/head -1; /usr/sbin/diskinfo /dev/rdsk/$FIRSTRAWDEVICE
  • Output contains: ^SCSI describe of /dev/rdsk/ (regex)
