## Summary of Viewing data usage by table

This feature in the Data Management Console allows ServiceNow customers to analyze and monitor data usage at the individual table level.
It provides a daily refreshed summary of storage consumption and record counts for selected tables, helping customers understand a table's impact on overall storage and manage data growth effectively.

## Key Features

* **Table Size Monitoring:** Displays total storage used by a specific table in gigabytes, with updates reflecting changes within 24 hours.
* **Associated Table Size:** Shows storage used by related tables that contain dependent records such as attachments, audits, and journals.
* **Data Usage Trends:** Tracks and compares storage usage over weeks or months for the table and its associated tables, including percentage changes since a specified date.
* **Driver Tables Identification:** Identifies tables that contribute to the size growth of the current table (e.g., Incident, Problem, and Change Request tables for the Task table), including their size and record counts.
* **Associated Tables Overview:** Details the volume and record counts of tables storing dependent records tied to the current table, such as audit or attachment tables.
* **Data Management Rule Creation:** Enables customers to manage data growth by creating data management rules on the current table or its driver tables to control storage impact.

## Key Outcomes

* Gain comprehensive visibility into how individual tables and their related tables contribute to storage usage.
* Monitor and analyze storage trends to proactively address data growth issues.
* Identify driver and associated tables to target specific areas for data management and optimization.
* Leverage data management rules to control and reduce storage consumption, helping maintain system performance and cost efficiency.

## Access Requirements

Users must have the **admin role** to access the Data Management Console and view data usage by table.

## How to Access

Navigate in the ServiceNow instance to **All \> System Data Management \> Data Management Console \> Tables**, then select the desired table to view its data usage details.  
View a summary of data usage for an individual table.

## Key benefits {#data-management-table-data__section_zvd_nbn_rfc}

* Analyze data usage at the table-level.
* Monitor data usage for a specific table over time.
* Access a comprehensive view of a table's impact on storage usage by checking the size and record count of driver tables and associated tables.

## Required ServiceNow AI Platform roles {#data-management-table-data__section_wsm_fvc_mfc}

The admin role is required to view the Data Management console.

## Accessing data usage by table in the Data Management Console {#data-management-table-data__section_lvm_mvc_mfc}

Access data usage for a specific table in the Data Management Console by navigating to AllSystem Data ManagementData Management ConsoleTables and selecting the table.

## Table size (GB) {#data-management-table-data__section_ww3_pvq_hfc}

View the total amount of storage used by the current table. If you've made significant changes to your data recently, it might take up to 24 hours for changes to appear.

Track storage usage over time by viewing the percentage increase or decrease since a specific date.

## Associated table size (GB) {#data-management-table-data__section_zzb_qvq_hfc}

Associated tables contain records that don't have a lifespan of their own. Examples include attachments, audits, and journals.

* View the total amount of storage used by associated tables.
* Track the rate of storage usage by viewing the percentage change since a specific date.
* Address growth in associated tables by creating data management rules on the current table.
{#data-management-table-data__ul_kvq_qzq_hfc}

## Data usage trend {#data-management-table-data__section_gdv_qvq_hfc}

Monitor data usage for the current table over time.

* Track the size of the current table over weeks or months.
* Compare data usage between the current table and associated tables over time.
{#data-management-table-data__ul_rxy_lgr_hfc}

## Driver tables {#data-management-table-data__section_ohw_1fr_hfc}

Driver tables are those that contribute to the size of another table. For example, the Incident \[incident\], Problem \[problem\], and Change Request \[change_request\] tables contribute to the growth of the Task \[task\] table, which makes
them driver tables.

* Determine which tables are driving volume to the current table.
* View the size of each driver table and the total record count in each driver table.
* Address growth in the current table by creating data management rules in the driver tables.
{#data-management-table-data__ul_m3p_cfr_hfc}

## Associated tables {#data-management-table-data__section_o5k_rvq_hfc}

Associated tables store records like attachments, audit records, and journal entries that don't have a lifespan of their own. For example, the Sys Audit \[sys_audit\], Attachment \[sys_attachment\], and Journal Entry \[sys_journal_field\]
are tables associated with the Incidents table, which contributes volume to these tables.

* Determine how much volume the current table is contributing to associated tables.
* View the size of associated records and the total record count in each associated table.
* Address growth in associated tables by creating data management rules on the current table.
