Description: How to monitor EMC Isilon Clusters through the REST API.

Additional Keywords: Isilon


This article explains how to monitor EMC Isilon Clusters through the REST API.


To use the EMC Isilon REST connector, a user must be specified. It must have an assigned role with sufficient privileges on the system. The following read privileges are required for the role associated to the user:

  • Platform API Login (ISI_PRIV_LOGIN_PAPI)
  • Devices (ISI_PRIV_DEVICES)
  • Network (ISI_PRIV_NETWORK)

These permissions can be set through the CLI, using the command isi auth roles modify. For example:

isi auth roles modify “rolename” --add-priv-ro=ISI_PRIV_LOGIN_PAPI --add-priv-ro=ISI_PRIV_DEVICES --add-priv-ro=ISI_PRIV_SMARTPOOLS --add-priv-ro=ISI_PRIV_NETWORK

  1. Log in to TrueSight Presentation Server.
  2. Create a new policy:

    • Specify the general properties and agent selection criteria.
    • Add a monitoring configuration.
    • Select the Hardware Monitoring Solution.

    • In the Hardware Configuration section, click Add:

      Providing the Isilon Information

      • Indicate the name of the device you wish to monitor. This may be a label or the actual hostname.
      • Enter the IP address of the device. If no IP address is provided, the device name previously specified will be used.
      • Select Storage (Array, Switch, Library) as Device Type.
      • Enable HTTP and provide the required configuration information.
