# Performing Log Analysis

Veeam Intelligent Diagnostics is a feature that allows you to automatically detect known issues in configuration and performance of backup infrastructure.

To use **Veeam Intelligent Diagnostics**:

1. Open Veeam ONE Web Client.
2. At the top right corner of the Veeam ONE Web Client window, click **Configuration**.
3. In the configuration menu on the left, click **Data Collection**.
4. In the inventory pane, select the desired object in the **Object Name** column.
5. In the **Veeam Intelligent Diagnostics** drop-down list specify the diagnostic actions:

   - Click **Start log analysis** to start analysis.
   - Click **Stop log analysis** to stop analysis.
   - Click **Schedule** to schedule a start time for log analysis.

For details on Veeam Intelligent Diagnostics, see [Veeam Intelligent Diagnostics](intelligent_diagnostics.md).

Veeam Analytics service allows you to perform log analysis according to the defined schedule or manually:

- When a scheduled log analysis session starts, Veeam Analytics service analyzes Veeam Backup & Replication logs for the last 48 hours or since the last successful log analysis session (whichever is later).

  By default, Veeam Analytics service is set to perform log analysis daily at 7:00 AM. To change the default log analysis schedule, see [Scheduling Automated Log Analysis](vbr_log_analysis.md#schedule).

- When you start a log analysis session manually, Veeam Analytics service analyzes Veeam Backup & Replication logs for the last 24 hours or since the last successful log analysis session (whichever is later).

  For details on starting log analysis manually, see [Starting Log Analysis Manually](vbr_log_analysis.md#manual).

::: note

If silence mode is active for the target Veeam Backup & Replication server, log analysis cannot be run manually or by schedule.
