Nimble Storage Rest API
Overview​
HPE Nimble Storage is a predictive flash storage technology developed by Nimble Storage that was based in San Jose, California founded in early 2008. Nimble Storage produced hardware and software products for data storage, specifically data storage arrays that use the iSCSI and Fibre Channel protocols and includes data backup and data protection features. Nimble is a subsidiary of Hewlett Packard Enterprise.

FAQ​
Why do I get the following error message:​
UNKNOWN: 500 Can't connect to myserver.mycompany.com:19999​
This error message means that the Centreon Plugin couldn't successfully connect to the Nimble device API.
Check that no third party device (such as a firewall) is blocking the request.
A proxy connection may also be necessary to connect to the API.
This can be done by using this option in the command: --proxyurl='http://proxy.mycompany:8080'.
UNKNOWN: 501 Protocol scheme 'connect' is not supported |​
When using a proxy to connect to the Nimble API, this error message means that the Centreon Plugin library does not support
the proxy connection protocol.
In order to prevent this issue, use the curl HTTP backend by adding the following option to the command: --http-backend='curl'.
UNKNOWN: Cannot load module 'Net::Curl::Easy'​
This error message means that a Perl library required to use the curl backend is missing.
In order to fix this issue, install the 'Net::Curl::Easy' Perl library using the following command:
yum install perl-Net-Curl
