TS: BI Server system worksheet
The TS:BI Server system worksheet contains data related to how users interact with various systems in ThoughtSpot. This includes database latency, browser clients, size of responses, and more. The TS Stats: Latency Visualizations system Liveboard uses data from the TS:BI Server worksheet to display average and maximum latency for your visualizations. You can filter by a specific visualization ID on the Liveboard to find specific latency information.
Reference the following table to learn more about the most commonly used columns in the TS:BI Server worksheet:
| Column | Description | 
|---|---|
| Database Latency (us) | Represents the time in microseconds fetching data from Falcon. This is only query latency, and does not represent the time fetching metadata or rendering the visualization. | 
| HTTP Response Code | HTTP response code returned to ThoughtSpot. | 
| Incident ID | A unique identifier for each request made to ThoughtSpot. | 
| Attribute Count | Number of attributes in the search query. | 
| Join Count | Number of joins in the search query. | 
| Measure Count | Number of measures in the search query. | 
| Response Size | Size of response to user’s request in ThoughtSpot in bytes. | 
| Latency (us) | Response time in microseconds. Round trip latency in microseconds. This is the amount of time between firing the query and returning data to the front end. | 
| Timestamp | Time when the event occurred in yyyyMMdd HH’:’mm’:’ss format. | 
| Top Count | Count of queries with  | 
| URL | HTTP path of the request. | 
| User | Username of user associated with the request. | 
| Uses System Table | Set when Answer is based on tables. | 
| Uses User Data | Set when Answer is based on tables loaded using TQL. | 
| Uses Worksheet | Set when Answer is based on a Worksheet or Model. | 
| Query Text | Text of the search query. | 
| Answer Book GUID | GUID of the Liveboard or Answer. | 
| Answer Book Name | Name of the Liveboard or Answer. | 
| Impressions | The number of events based on the User Action type. An Answer viewing counts as one impression, while a Liveboard viewing counts as a partial impression, depending on the number of visualizations it contains. | 
| Browser Type | Browser type associated with the request. | 
| Browser Version | Browser version associated with the request. | 
| Viz Id | ID of visualization. Can be retrieved from URL parameters of the visualization. | 
| Client Id | Client ID used to uniquely identify clients | 
| Client Type | Describes the access mode of ThoughtSpot: either the classic Answer experience, new Answer experience, accessed via Mobile, or accessed via Embedded SDK. | 
| User Action | User actions in ThoughtSpot. For more information, see User action code reference. | 
| User Id | ID of the user associated with the request. | 
| Org Id | Unique ID of Org associated to the request (only applicable to Org-enabled accounts). | 
| Org Name | Name of Org associated to the request (only applicable to Org-enabled accounts). |
