Description

This connector provides the monitoring of HBA cards on all Linux systems through the multipath utility.

Connector ID: LinuxMultipath

Target

Typical platform: Any system with multipath

Operating system: Linux

Prerequisites

• multipath

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 hwsagent account:

hwsagent ALL=(root) NOPASSWD: multipath

Examples

hws HOSTNAME -t linux -f LinuxMultipath --ssh -u USER --sudo-command-list multipath

hosts:
- host:
    hostname: <HOSTNAME> # Change with actual host name
    type: linux
  selectedConnectors: [ LinuxMultipath ] # Optional, to load only this connector
  ssh:
    username: <USERNAME> # Change with actual credentials
    password: <PASSWORD> # Encrypted using hws-encrypt
    useSudo: true
    useSudoCommands: [ "multipath" ]
