如何获取超过45天的ADF管道1月历史运行日志？

Core Limitations & Eligibility #

• Built-in ADF Monitoring: Only retains logs for the last 45 days. If your January logs fall outside this window, you can’t retrieve them through this tool.
• Azure Data Factory Analytics (Powered by Log Analytics): Can access historical logs only if you enabled Diagnostic Settings for your ADF instance to send logs to a Log Analytics workspace before January 1st. Logs are collected from the moment you enable the setting—no retroactive data capture is possible.

Step-by-Step Process to Query Historical Logs via Log Analytics #

1. Verify Diagnostic Settings Were Active in January #

• Go to your Azure Data Factory resource in the Azure Portal.
• Navigate to Monitoring > Diagnostic settings (left sidebar).
• Check for an existing setting that includes the PipelineRuns log category and sends data to a Log Analytics workspace. Confirm the setting’s creation date is prior to January 1st.

2. Access the Linked Log Analytics Workspace #

• From the Diagnostic Settings page, click the workspace name to open it directly.
• Alternatively, search for Log Analytics workspaces in the Azure Portal and select the relevant workspace.

3. Run a Kusto Query to Fetch January Pipeline Runs #

• In the workspace, go to Logs (left sidebar).
• Use this Kusto query to filter runs from your target January period (adjust the year as needed):

ADFPipelineRuns
| where TimeGenerated between (datetime(2024-01-01 00:00:00) .. datetime(2024-01-31 23:59:59))
| project PipelineName, RunId, Status, StartTime, EndTime, DurationMs, ErrorMessage
| sort by StartTime desc

• Modify the project clause to include additional fields (e.g., TriggerName) based on your needs.

4. Export or Analyze Results #

• Use the Export button at the top of the results pane to save logs as CSV, Excel, or send to Power BI.
• Add Kusto operators like summarize or filter to analyze run trends, failure rates, or bottlenecks.

If Diagnostic Settings Were Not Enabled in January #

If you didn’t configure diagnostic logs before January, there’s no way to retrieve those historical pipeline run logs via Azure’s built-in tools. ADF does not retain logs beyond the 45-day window unless explicitly configured to send them to an external store (Log Analytics, Storage Account, Event Hub) before the logs are generated.
