asp.net-core – 丰富Serlilogs,每个hangfire工作具有独特的价值

Log.Logger = new LoggerConfiguration()
    .ReadFrom.Configuration(Configuration)
    .WriteTo.Seq(serverUrl: serverUrl,apiKey: apiKey)

    // Enrich the logs with a tracking id. Will be a new value per request
    .Enrich.WithProperty("TrackingId",Guid.NewGuid())

    .CreateLogger();

BackgroundJob.Enqueue<MyService>(myService => myService.DoIt(someParameter));

为了它的价值,我最终使用下面显示的服务器/客户端过滤器和GlobalJobFilters注册将其关闭.我遇到的一个令人烦恼的问题是,AutomaticRetryAttribute默认添加到GlobalJobFilters集合,而 will log errors for failed jobs类则不知道在我们的自定义JobLoggerAttribute中创建的Serilog LogContext.就个人而言,我知道我只允许手动重试,所以我只删除了该属性并处理了IServerFilter.OnPerformed方法中的错误.检查我的帖子的结尾,看看如果它适合你,如何删除它.

如果要允许自动重试,则需要：1)创建一个自定义属性来装饰AutomaticRetryAttribute并使其知道自定义LogContext,2)再次从GlobalJobFilters集合中删除默认的AutomaticRetryAttribute,并且3)添加你的decorator属性集合.

public class JobLoggerAttribute : JobFilterAttribute,IClientFilter,IServerFilter
{
    private ILogger _log;

    public void OnCreating(CreatingContext filterContext)
    {
        _log = GetLogger();

        _log.Information("Job is being created for {JobType} with arguments {JobArguments}",filterContext.Job.Type.Name,filterContext.Job.Args);
    }

    public void OnCreated(CreatedContext filterContext)
    {
        _log.Information("Job {JobId} has been created.",filterContext.BackgroundJob.Id);
    }

    public void OnPerforming(PerformingContext filterContext)
    {
        if (_log == null)
            _log = GetLogger();

        _log.Information("Job {JobId} is performing.",filterContext.BackgroundJob.Id);
    }

    public void OnPerformed(PerformedContext filterContext)
    {
        _log.Information("Job {JobId} has performed.",filterContext.BackgroundJob.Id);

        if (filterContext.Exception != null)
        {
            _log.Error(
                filterContext.Exception,"Job {JobId} failed due to an exception.",filterContext.BackgroundJob.Id);
        }

        _log = null;
    }

    private ILogger GetLogger()
    {
        return Log.ForContext(GetType()).ForContext("HangfireRequestId",Guid.NewGuid());
    }
}

注册……

GlobalJobFilters.Filters.Add(new JobLoggerAttribute());

删除AutomaticRetryAttribute …

var automaticRetryFilter = GlobalJobFilters.Filters.Where(x => x.Instance is AutomaticRetryAttribute).Single();
GlobalJobFilters.Filters.Remove(automaticRetryFilter.Instance);
