The device inventory display is divided into four sections: The device listing, the sort and filter bar, the command bar, and the scope limiter.
You can limit the scope of the device listing by clicking on Scope, thereby extending the scope limiter downwards.
In the scope limiter, narrow down the scope of devices by specifying location, process association, device group, network, or any combination thereof. If you want to reset the limit of a given dimension, simply click on the dimension's name (for example, click on "Location" if you want to reset a location filter).
Below the context scope you can filter the output in respect to device lifecycle stage (planned, installed, testing etc.). You can also select "Unidentified" if you want unidentified devices to show in the device listing. Unidentified devices are devices about only very basic details such as an IP or MAC address are known.
Sort and filter bar
You can sort the device listing by any column if you simply click on the column header.
In order to filter list entries in any column, input your filter term in the filter line of that column. Output will be filtered as you type. If you want to filter for a string contained within column text, preceed your search string with a percent sign ("%"). For number fields you can use "<" and ">" to limit the output to values smaller than or greater than the filter value.
You can use filters in multiple columns simultaneously. To reset all filters, click the "Reset Filters" button in the command bar.
The device listing contains entries for all devices that match your scope and filter settings.
Color codes indicate the device type at a glance:
- Network gear is shown in blue
- Automation gear is shown in grey
- Laptops are shown in light yellow
- Sensors are shown in bright yellow
- Actuators are shown in red
- Everything else is shown in white.
You may see multiple entries for a single device if that device has multiple network interfaces. This allows you, for example, to filter for specific IP addresses in the Address column.
For location, process association and device group, only the last leaf of the tree is shown. The full tree is displayed in a tooltip when you hover the mouse over the field value.
The command bar allows you to execute various commands which for the most part affect the entries that you have selected in the device listing.
In order to select an entry, use the left mouse button. You can select multiple entries with Shift-left click and Control-left click.
- Profile launches the device profile of the selected entry. This is the button that you will use most often, since a device profile shows all the information related to a given entry in the most comprehensive form.
- Export will export the device listing that you see (i.e. with all given scope and filter restrictions) as an Excel spreadsheet.
- Add allows you to manually add a new device. This can be useful for devices that cannot be examined using OT-BASE Asset Discovery.
- Clone clones an existing entry with most of its metadata. You are always prompted to input a new device ID for clones since the device ID must always be unique. Cloning devices can be helpful if you want to use OT-BASE for planning purposes, i.e. specifying the configuration of a new system. By default, the clone will be assigned the "planned" lifecycle stage.
- Merge lets you merge duplicate entries for the same device. Duplicate entries can occur when a device is identified independently by separate Asset Discovery nodes, for example because the device is hosted in multiple networks.
- Edit launches the edit dialog for the selected device, if you have read/write permission for the device.
- Remove removes a device from the inventory listing. The removal process is a two-step process. When you click Remove for the first time, the device's lifecycle status is set to "decommissioned". When you display the entry with decommissioned devices on and remove it again, all device data is actually removed from the database, and the device ID can be re-used. Decommissioned entries allow you to still access the configuration details of devices, should the need evolve at some point in time.
- Set Release lets you set a release version for the selected devices. Release management is tied to Distributed Control Systems and can be accessed in INVENTORY/SYSTEMS.
- Reset Filters resets any filters that you may have set in the filter bar. It's just a more convenient way to revert to the default listing without having to remove all filter terms individually.
- Impact Analysis executes an impact analysis for the selected device, informing you about the potential side effects of configuration changes for this device on other devices and processes. An impact analysis requires that you have already assigned physical process associations and data flow.
- Request Change Case opens a change case for the selected devices, if your permissions include this authority.
Filter by tags
If tags have been assigned to any device, you can filter for such devices by opening the Filter by tags dialog.
In the lower part of the dialog you see the available tags. If there is a lot of tags, you can filter the selection by inputting text in the "Add tag" edit field, which will filter the available tags as you type. Clicking on "Filter" will close the dialog box and display the results.
Tags can be added to devices in the Edit dialog (see above) if you have read/write permission for inventory entries.
