I can view my opentelemetry in transaction search but they do not show up in log analytics. I have the diagnostic setting configured correctly.

    Hello McClure, Timothy,

    For this issue check Under Diagnostic setting make sure 'Send to Log Analytics Workspace' is selected also make sure the traces are selected under Logs Category groups. Screenshots below for your reference.

    1. Querying Log Analytics: When querying Log Analytics, make sure you’re using the correct Kusto query. You can use the following query to look for traces:

    AzureDiagnostics | where Category == "DistributedTracing" | project TimeGenerated, Category, OperationName, Level, CorrelationId, DurationMs, properties_s | order by TimeGenerated asc
    

    2. Data Retention Settings: Verify the data retention settings in your Log Analytics workspace. If logs are older than the retention period, they won’t be available for querying.

    The Data Retention can be checked under.

     3. Data Ingestion Delay: Sometimes there can be a delay in data appearing in Log Analytics. Check back after some time to see if the traces show up.
