Limit length of log line in RequestLogsFeature

mauve · October 27, 2023, 6:20am

Hi,

I am using the CsvRequestLogger to log each request to the filesystem.

Due to logging the whole response the log lines could get really long.

Is there a way to set a limit for log lines?

Greetings
Andre

You can customize what gets saved by registering a RequestLogFilter:

Plugins.Add(new RequestLogsFeature {
    RequestLogFilter = (req,logEntry) => ...
});

But if you only log a partial Request/Response you’ll break deserialization which will prevent being able to view latest logs with GetLatestLogs().

Best to limit which responses are logged by using the available configuration options, e.g:

github.com

ServiceStack/ServiceStack/blob/main/ServiceStack/src/ServiceStack/RequestLogsFeature.cs#L79-L110


      
          public Type[] ExcludeRequestDtoTypes { get; set; }
          
          /// <summary>
          /// Don't log request body's for services with sensitive information.
          /// By default Auth and Registration requests are hidden.
          /// </summary>
          public Type[] HideRequestBodyForRequestDtoTypes { get; set; }
          
          /// <summary>
          /// Don't log Response DTO Types
          /// </summary>
          public Type[] ExcludeResponseTypes { get; set; }
          
          /// <summary>
          /// Limit logging to only Service Requests
          /// </summary>
          public bool LimitToServiceRequests { get; set; }
          
          /// <summary>
          /// Customize Request Log Entry

Another option is to use an external framework like NLog which I’ve been using for over a decade in all my projects. I log from PreRequestFilters, GlobalResponseFilters and ServiceExceptionHandlers. Advantage is you can really format the output to your heat’s content. Downside is you’ll lose the GetLatestLogs, etc that’s built in to ServiceStack.
