Manage glass tables in ITSI

In a future ITSI release, you will no longer be able to create or clone glass tables in the classic framework. You will still be able to edit existing classic glass tables. All classic glass tables in your environment will be cloned to the beta framework. The beta framework will soon become the official and only framework, so it is recommended that you begin to use this new framework exclusively. For more information, see Overview of the beta glass table editor in ITSI.

Glass tables allow you to visualize services and KPIs in your environment in a flexible way. Manage the glass tables that you create on the glass tables lister page.

To access the glass tables lister page, click Glass Tables on the IT Service Intelligence menu bar.

Modify a glass table

After you create a glass table, you can continue to make changes to it.

1. From the list of glass tables, click Edit next to the glass table that you want to modify.
2. Choose whether you want to edit the glass table itself, edit the title or description, or edit permissions.

Clone a glass table to make a template

You can clone a glass table to make a template so you can make experimental changes on another version.

1. From the list of glass tables, click Edit next to the glass table that you want to modify.
2. Click Clone.
3. Type a new title.
4. (Optional) Type a new description.
5. (Optional) Change the permissions of the cloned glass table.
6. Click Clone.

Access to glass tables

All users can view glass tables, but you must have the itoa_analyst, itoa_team_admin, or itoa_admin role, or have the "write_itsi_glass_table" capability to create and modify glass tables. If you do not have the necessary permissions, talk to your Splunk IT Service Intelligence administrator.

Performance and storage of glass tables

Glass table content is stored in the KV store. The glass table definitions are stored in the itsi_pages collection. Files added to glass tables, such as images, are stored in the sa-itoa_files collection. Custom widgets, images, and other items that you add to a glass table are all stored in this collection.

The performance of individual glass tables depends on the number of search widgets on a glass table. When you open a glass table for viewing, each search runs at the same time. Searches on glass tables with 200 or more search widgets could take 10-15 seconds to show data on the glass table.

Export a glass table

You can export a glass table to share it with others or to back it up. For more information, see Create a partial backup of ITSI in the Administration Manual.
