What is this?
Plug ADO.NET timings into ILogger with scopes for request id — structured, redacted.
Why should you care?
ShopNest on-call greps request id across API and SQL logs.
See it live — copy this example
Use a .NET console or API project with SQL Server LocalDB. Run dotnet run after pasting.
using (_logger.BeginScope(new Dictionary<string, object>{{"RequestId", requestId}}))
{
_logger.LogInformation("sql {Proc} started", cmd.CommandText);
await cmd.ExecuteNonQueryAsync(ct);
}What happened?
- ILogger abstractions.
- Scopes carry request id.
- Don’t log parameter secrets.
Practice next
- Inject ILogger
. - Log proc + duration.
- Scope request id.
- LogEvent on failure with Number.
- Sampling for chatty reads.
Remember
ILogger + scopes. Duration fields. Redaction.
ShopNest correlated SQL logs
RequestId links API↔SQL.
Outcome: Faster incident tracing.
