Description

This connector discovers the status of an EMC Isilon Storage Cluster

Connector ID: EMCIsilon

This connector is superseded by:

• EMCIsilonSNMP

Target

Typical platform: EMC Isilon

Operating system: Storage System

Prerequisites

Leverages: EMC Isilon SSH interface

Technology and protocols: System Commands

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

• /usr/bin/isi_for_array
• /usr/bin/isi

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 hwsagent account:

hwsagent ALL=(root) NOPASSWD: /usr/bin/isi_for_array
hwsagent ALL=(root) NOPASSWD: /usr/bin/isi

Examples

hws HOSTNAME -t storage -f EMCIsilon --ssh -u USER --sudo-command-list /usr/bin/isi_for_array,/usr/bin/isi

hosts:
- host:
    hostname: <HOSTNAME> # Change with actual host name
    type: storage
  selectedConnectors: [ EMCIsilon ] # Optional, to load only this connector
  ssh:
    username: <USERNAME> # Change with actual credentials
    password: <PASSWORD> # Encrypted using hws-encrypt
    useSudo: true
    useSudoCommands: [ "/usr/bin/isi_for_array", "/usr/bin/isi" ]

Connector Activation Criteria

The EMC Isilon (SSH) 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: if [ -f /usr/bin/isi ] ; then echo ms_hw_isi_found ; fi
  • Output contains: ms_hw_isi_found (regex)
• The command below succeeds on the monitored host
  • Command: /bin/zsh -c " /usr/bin/isi_for_array /usr/bin/isi status -w"
  • Output contains: Cluster Name: (regex)
