How to create a custom widget for SFP Power or Voltage on the network advisor... currently we using 12.3.3 version but i couldn't find the option.
I'd follow the following steps to ensure that you're able to create custom widgets for SFP Power and Voltage.
1) Create your own Dashboard by clicking on the Add button. This ensures that you are creating a separate dashboard, where you will be able to create and add newer widgets to the Dashboard.
2) The click on the Customize Dashboard button on the Top Left of the toolbar. This will show you the existing widgets and also give you the option of adding a new widget (Status or Performance).
3) Click on the Performance Tab and select Add. Here if you go to the Ports section you will be able to create top/bottom/Distribution/Time Series widgets and select the measures that you want to pick for the widget.
