21 | | -### Step-by-Step Instructions to Resolve High Data Usage |
| 21 | +1. Identify high data tables: |
22 | 22 |
|
23 | | -1. **Identify High Data Tables:** |
24 | | - |
25 | | - - Use the `AzureDiagnostics` table to determine which Reference are sending large amounts of data. |
26 | | - - Run the following query in your Log Analytics workspace: |
| 23 | + 1. Use the `AzureDiagnostics` table to determine which listed references are sending large amounts of data. |
| 24 | + 1. To identify the reference that's contributing to high data usage, run the following query in your Log Analytics workspace: |
27 | 25 |
|
28 | 26 | ```plaintext |
29 | 27 | AzureDiagnostics | distinct _ResourceId |
30 | 28 | ``` |
| 29 | +2. Review the diagnostic settings: |

|
32 | | - - This will help you identify the Reference contributing to high data usage. |
33 | | -
|
34 | | -2. **Review Diagnostic Settings:** |
35 | | -
|
36 | | - - Navigate to the diagnostic settings of the identified Reference. |
37 | | - - Remove unnecessary diagnostic settings if the data is not needed. This will stop the data from being sent to the AzureDiagnostics table. |

|
41 | | - Review the articles in the [reference section](#reference) to understand the costs associated with your Log Analytics workspace. |
| 31 | + 1. Navigate to the diagnostic settings of the identified reference. |
| 32 | + 1. Remove unnecessary diagnostic settings if the data is not required. This step stops the data from being sent to the AzureDiagnostics table. |
