Getters and checks require a license-file to work. You can download a license-file for your product from the distributors website (portal) typically at the same place from where you got the package with the software.
The license-file has a dat-extension and placing it into the directory /usr/local/check_netapp_pro/etc will always work. To place it into an other directory consult the executables --help.
To get information about the license (duration, …) open the license-file with a text editor.
Check NetApp-ZAPI requires a valid license file. The checks will stop if the license expires. Therefore we highly recommend to install a check which will warn you in advance. See the License Files-chapter and/or the etc.example/license.cfg file for details.
