Monitoring NetApp Storage Devices over a RESTful API
NetApp® ONTAP® 9.6 and later versions include support for an expansive RESTful web services API. In comparison to an ONTAPI® application, the REST API offers a vastly simplified and workflow-driven user experience, allowing you to perform multiple operations on the storage objects with a single API. REST is the industry standard for API development, and the ONTAP REST API provides a great opportunity to automate your storage deployments.
I could basically only find the Centreon NetApp REST-API plugin which does do a number of things, but as it couldn’t do everything we needed, I had to write two more plugins. So the plugins we use now for the NetApp Monitoring are the following:
- centreon_netapp_ontap_restapi.pl
- check_netapp_api_cluster_network.pl
- check_netapp_api_node_disk_totals.pl
The monitoring Service Commands we use with NetEye for the above Services are the following:
- NetApp Aggregate Status:
/usr/lib/centreon/plugins/centreon_netapp_ontap_restapi.pl --api-password 'password' --api-username 'user' --hostname <hostname|ip> --insecure --mode aggregates --verbose
- NetApp Cluster Status:
/usr/lib/centreon/plugins/centreon_netapp_ontap_restapi.pl --api-password 'password' --api-username 'user' --hostname <hostname|ip> '-insecure --mode cluster --statefile-dir /neteye/shared/icinga2/data/lib/centreon-plugins --verbose
- NetApp Hardware Health Status:
/usr/lib/centreon/plugins/centreon_netapp_ontap_restapi.pl --api-password 'password' --api-username 'user' --hostname <hostname|ip> --insecure --mode hardware --verbose
- NetApp Node Disk:
/neteye/shared/monitoring/plugins/check_netapp_api_node_disk_totals.pl -H <hostname|ip> -c 90 -f -p 'password' -u 'user' -w 80
- NetApp Node Network Status:
/neteye/shared/monitoring/plugins/check_netapp_api_cluster_network.pl -H <hostname|ip> -e 'e0a|e0b' -f -p 'password' -r -u 'user' -v
- NetApp SnapMirrors Status:
/usr/lib/centreon/plugins/centreon_netapp_ontap_restapi.pl --api-password 'password' --api-username 'user' --hostname <hostname|ip> --insecure --mode snapmirrors --verbose
- NetApp Volumes Status:
/usr/lib/centreon/plugins/centreon_netapp_ontap_restapi.pl --api-password 'password' --api-username 'user' --critical-usage-prct 90 --filter-vserver-name '^(?!.*_DR).*' --hostname <hostname|ip> --insecure --mode volumes --verbose --warning-usage-prct 80
We then created some ITOA dashboards for all the performance data we get; here’s an example for the Volumes Dashboard:
So with this I guess you have all the necessary information to be able to add your own NetApp RESTful API Monitoring inside your monitoring system.
