SplunkLogger 1.0.2

SplunkLogger

This is a C# .Net Core 2 Splunk ILogger implementation developed at VTEX to send log to Splunk

Package Name	Release
SplunkLogger

It was developed to be integrated to .Net Core 2 logging abstractions.

Features

• ILoggerProviders (SplunkHECJsonLoggerProvider, SplunkHECRawLoggerProvider, SplunkTcpLoggerProvider and SplunkUdpLoggerProvider)
• ILoggers (HEC (Raw and Json) and Socket (TCP and UDP)
• Custom Configurations
• Batch Manager class (Improve Splunk HEC performance sending data as batch)

Usage

After add SplunkLogger nuget library

PM> Install-Package SplunkLogger

You should initialize a new SplunkLoggerConfiguration and the logger provider at Configure method at Startup class:

static readonly ILoggerFormatter formatter = null;

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
    var splunkConfiguration = new SplunkLoggerConfiguration()
    {
        HecConfiguration = new HECConfiguration()
        {
            SplunkCollectorUrl = "https://localhost:8088/services/collector",
            Token = "753c5a9c-fb59-4da0-9064-947f99dc20ba"
        }
    };
    loggerFactory.AddHECRawSplunkLogger(splunkConfiguration, formatter);
    app.UseMvc();
}

In this case above we added a Splunk HEC Raw logger without any custom formmater as log provider.

Now in your controller you can log normally, for instance:

[Route("api/[controller]")]
public class ValuesController : Controller
{
    readonly ILogger logger;

    public ValuesController(ILoggerFactory loggerFactory)
    {
        logger = loggerFactory.CreateLogger<ValuesController>();
    }

    // GET api/values
    [HttpGet]
    public IEnumerable<string> Get()
    {
        logger.LogCritical(new EventId(-1, "Values Controller"), new NotImplementedException(), "Error on GET api/values route");
        return new string[] { "value1", "value2" };
    }
}

VTEXSplunkLogger

For us at VTEX we need more customized log entries at Splunk and also we need easier ways to call for log registration during the code and for that we created this VTEXSplunkLogger library.

This project contains all VTEX extra classes designed to facilitate to log registration and also, all classes to customize .Net Core 2 log abstraction to a customized log entry at Splunk

Package Name	Release
VTEXSplunkLogger

Features

• ILoggerExtensions (Allow easy log creation)
• LoggerFactoryExtensions (Simplify loggerFactory add provider method call)
• VTEXSplunkLoggerFormatter (Custom ILoggerFormatter responsable for create VTEX custom text to Splunk)

Usage

After add VTEXSplunkLogger nuget library

PM> Install-Package VTEXSplunkLogger -Version 1.0.0 -Source https://www.myget.org/F/vtexlab/api/v3/index.json

You should initialize a new SplunkLoggerConfiguration and the logger provider at Configure method at Startup class:

static readonly ILoggerFormatter formatter = new VTEXSplunkLoggerFormatter();

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
    var splunkConfiguration = new SplunkLoggerConfiguration()
    {
        HecConfiguration = new HECConfiguration()
        {
            SplunkCollectorUrl = "https://localhost:8088/services/collector",
            Token = "753c5a9c-fb59-4da0-9064-947f99dc20ba"
        }
    };
    loggerFactory.AddHECRawSplunkLogger(splunkConfiguration, formatter);
    app.UseMvc();
}

using Vtex;
//other usings ..

[Route("api/[controller]")]
public class ValuesController : Controller
{
    readonly ILogger logger;

    public ValuesController(ILoggerFactory loggerFactory)
    {
        logger = loggerFactory.CreateLogger<ValuesController>();
    }

        logger.DefineVTEXLog(LogLevel.Critical, 
                             "Values Controller", 
                             "api/values", 
                             string.Empty, 
                             new NotImplementedException(), 
                             new Tuple<string, string>("method", "GET"));
        return new string[] { "value1", "value2" };
    }
}
