Description

This connector discovers Emulex HBAs of servers running on UNIX or Linux using the hbacmd utility provided with the Emulex Drivers.

This connector supersedes:

• CpqHBA^[2]
• SMISHBA^[3]

emulex^[4] enterprise^[5] hardware^[6] linux^[7] solaris^[8]

Target

Typical platform: Any system with Emulex

Operating systems: Linux, Oracle Solaris

Prerequisites

Leverages: Emulex's hbacmd utility

Technology and protocols: Command Lines

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

• hbacmd

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: hbacmd

Examples

metricshub HOSTNAME -t linux -c +EmulexHbacmd --ssh -u USER --sudo-command-list hbacmd

resourceGroups:
  <RESOURCE_GROUP>:
    resources:
      <HOSTNAME-ID>:
        attributes:
          host.name: <HOSTNAME> # Change with actual host name
          host.type: linux
        connectors: [ +EmulexHbacmd ] # Optional, to load only this connector
        protocols:
          ssh:
            username: <USERNAME> # Change with actual credentials
            password: <PASSWORD> # Encrypted using metricshub-encrypt
            useSudo: true
            useSudoCommands: [ "hbacmd" ]

Connector Activation Criteria

The Emulex HBAs (hbacmd) connector will be automatically activated, and its status will be reported as OK if all the below criteria are met:

• The command below succeeds on the monitored host
  • Command: hbacmd ListHBAs
  • Output contains: Port WWN (regex)
