EMC Isilon (SSH)

Description

This connector discovers the status of an EMC Isilon Storage cluster.

dell emc hardware storage

Enterprise Connector

This connector requires the Enterprise edition of MetricsHub.

Superseded Connector

This connector is superseded by:

• EMCIsilonSNMP

Target

Typical platform: Dell Isilon

Operating system: Storage System

Prerequisites

Leverages: EMC Isilon SSH interface

Technology and protocols: Commands

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

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

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 metricshub account:

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

Examples

CLI

metricshub HOSTNAME -t storage -c +EMCIsilon --ssh -u USER --sudo-command-list /usr/bin/isi,/usr/bin/isi_for_array

metricshub.yaml

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

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)
