Prerequisites

NetApp ONTAP configuration

A read-only account (login/password) is required.

Setup

Online IMP Licence & IT-100 Editions

Offline IMP License

1. Install the Centreon Plugin package on every Centreon poller expected to monitor NetApp ONTAP ressources:

yum install centreon-plugin-Hardware-Storage-Netapp-Ontap-Restapi

2. On the Centreon Web interface, install the 'NetApp Ontap Rest API' Centreon Plugin-Pack on the "Configuration > Plugin Packs > Manager" page

1. Install the Centreon Plugin package on every Centreon poller expected to monitor NetApp ONTAP ressources:

yum install centreon-plugin-Hardware-Storage-Netapp-Ontap-Restapi

2. Install the Centreon Plugin-Pack RPM on the Centreon Central server:

yum install centreon-pack-hardware-storage-netapp-ontap-restapi

3. On the Centreon Web interface, install the 'NetApp Ontap Rest API' Centreon Plugin-Pack on the "Configuration > Plugin Packs > Manager" page

Configuration

• Log into Centreon and add a new Host through "Configuration > Hosts".
• Apply the template HW-Storage-NetApp-Ontap-Restapi-custom and configure all the Macros:

Mandatory	Nom	Description
X	APIPORT	Port used. Default is 443
X	APIPROTO	Protocol used. Default is https
X	APIUSERNAME	Username to access to the API.
X	APIPASSWORD	Password to access to the API.
	APIEXTRAOPTIONS	Any extra option you may want to add to the command

FAQ

How do I test my configuration through the CLI and what do the main parameters stand for ?

Once the Centreon plugin installed, you can test it logging with the centreon-engine user:

/usr/lib/centreon/plugins/centreon_netapp_ontap_restapi.pl \    
    --plugin=storage::netapp::ontap::restapi::plugin \
    --hostname=netapp.centreon.com \
    --port=443 \
    --proto=https \
    --api-username='admin' \
    --api-password='xxxx' \
    --mode=volumes \
    --verbose

The command above checks the status of the volumes (--mode=volumes) of the NetApp storage netapp.centreon.com (--hostname=netapp.centreon.com) using the API username admin and the related password (--api-username='admin' --api-password='xxxx'). The API connection uses the HTTPS protocol (--proto=https) on the port 443 (--port=443).
