Hi Wei-Lin Ku,
-The AzureMetrics table stores aggregated metrics, while dimensions are found in AzureDiagnostics or through the Azure Monitor Metrics API, with Log Analytics designed for pre-aggregated data.
-Dimensions, such as jobId, are often available at the raw event level but may not be included in the AzureMetrics table. Instead, they are usually found in the AzureDiagnostics table or other logs.
-Certain Azure Batch metrics are logged in separate tables rather than in AzureMetrics. Reviewing Batch-specific tables in Log Analytics may provide further details.
-When using Kusto Query Language (KQL) to retrieve data, make sure your query specifically looks for dimensions, as some columns may not be included by default and can be accessed using project or extend.
-Dimensions may not appear in some cases due to permission restrictions or configuration settings within your Azure Monitor setup.
