How to have different log types using Serilog and ElasticSearch

Question

I am currently trying to change our system configuration to work with Serilog (instead of working with FileBeat as a shipper to LogStash)

We are also working with the log type field (which is easy to configure in the FileBeat config file) in our various queries and for indexing out logs on Elastic.

The problem is that when using Serilog we get the default type logevent, and I didn't find where I can configure it. I want to have an option to determine a specific log type per Serilog instance. At the moment I have the default type for all of my logs.

my Serilop Config is:

        var path = GetLogPath();
        var logger = new LoggerConfiguration()
            .MinimumLevel.Information()
            .Enrich.WithMachineName()
            .Enrich.WithProperty("RequestId", Guid.NewGuid())
            .WriteTo.RollingFile(
                pathFormat: path,
                outputTemplate: "{Timestamp:yyyy-MM-dd HH:mm:ss} [{Level:u4}] [{RequestId}] {Message}{NewLine}{Exception}", buffered: false, shared: true);
        logger.WriteTo.Elasticsearch(
                new ElasticsearchSinkOptions(new Uri(this.configurationService.ElasticSearchUrl())));

如何更改日志类型？

编辑

经过一番调查，我发现我想更改在LoggerConfiguration 中提交的typeName并且似乎我只能通过 AppConfig 文件来做到这一点，如果我要更改它，该更改将影响所有记录器实例。

我错过了什么吗？

只需对 Elasticsearch 接收器使用另一个重载即可：

var path = GetLogPath();
var logger = new LoggerConfiguration()
    .MinimumLevel.Information()
    .Enrich.WithMachineName()
    .Enrich.WithProperty("RequestId", Guid.NewGuid())
    .WriteTo.RollingFile(
        pathFormat: path,
        outputTemplate: "{Timestamp:yyyy-MM-dd HH:mm:ss} [{Level:u4}] [{RequestId}] {Message}{NewLine}{Exception}", buffered: false, shared: true);
logger.WriteTo.Elasticsearch(
        this.configurationService.ElasticSearchUrl(), typeName: "type");

因此您不必在应用程序设置中指定 typeName，它也不会影响所有实例。
