Programmable Reports

The Programmable Reports application enables the generation of reports using Python 2.7 scripts. Report jobs are run to generate reports. Each report job can generate multiple reports. You can schedule the report to run for a specific device or fabric. These reports are analyzed to obtain detailed information about the devices.

The REPORT template type is used to support the Programmable Reports feature. This template has two template subtypes, UPGRADE and GENERIC. For more information on the REPORT template, refer Report Template. A python SDK is provided to simplify report generation. This SDK is bundled with Nexus Dashboard Fabric Controller.


Note

A Jython template supports a maximum file size of 100k bytes. In case any report template exceeds this size, Jython execution may fail.

Nexus Dashboard Fabric Controller UI Navigation

To launch programmable reports on the Cisco Nexus Dashboard Fabric Controller Web UI, choose Operations > Programmable Reports.

The Reports window is displayed. This window has Report Definitions and Reports tabs. You can create reports from both the tabs by clicking Create Report. For information on creating a report job, refer Creating a Report Job. Refresh the window by clicking the Refresh icon.


Note

Report jobs and SAN user defined reports are not migrated when upgraded from Cisco DCNM 11.5(x) to Nexus Dashboard Fabric Controller Release 12.0.1a. You must create them again manually.

This chapter contains the following sections:

Create Report

Choose Operations > Programmable Reports. Click Create Report. The Create Report wizard appears.

To create a report job, perform the following steps:

Procedure

Step 1

Enter a name for the report job in the Report Name field.

Step 2

Click Select a template.

Step 3

Choose a report template from the drop-down list and click Select.

Based on the template you've chosen, provide required values to the fields that appear on the screen.

Step 4

Click Next to move to the Source & Recurrence step.

Step 5

Choose the frequency at which the report job should be run.

The following table shows the options available and their description.

Available Option

Description

Now

The report is generated now.

Daily

The report is generated daily at a specified time between the Start Date and End Date.

Periodic

The report is generated periodically in a time period between the specified Start Date and End Date. The interval of time between the reports can be specified in minutes or hours.

Note

 

When you are creating a Periodic NVE VNI Counters report, the report generation frequency has to be set to 60 minutes or more. If the frequency is less than 60 minutes, an error message is displayed.

Step 6

In the Email Report To field, enter an email ID or mailer ID if you want the report in an email.

You must configure SMTP settings in Settings > Server Settings > SMTP tab. If the Data service IP address is in private subnet, the static management route for SMTP server must be added in Cisco Nexus Dashboard cluster configuration.

Step 7

Choose the devices, fabrics, or VSANs in the Select device(s), Select fabric(s), or Select VSAN(s) area.
