Figure 1: Common View Settings (Device Filter Tab)
With this tab, you can specify a filter based on devices. If you do not want to apply this filter, simply check the check box. If you want to apply the filter, you would have to first uncheck the checkbox because otherwise the list box would remain un-editable.
Select the device on which you want to apply the filters. All the devices that you will select from the list box will be ORed together. E.g. If you have selected WS01 and WS03 from the above list, then it will bring all the records where device name is either WS01 or WS03.
