Description

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

This connector is superseded by:

• EMCIsilonSNMP^[2]

dell^[3] emc^[4] enterprise^[5] hardware^[6] storage^[7]

Target

Typical platform: EMC Isilon

Operating system: Storage System

Prerequisites

Leverages: EMC Isilon SSH interface

Technology and protocols: Command Lines

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

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

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)
