Tagging in .NET SDK

Thundra's .NET agent enables you to add custom tags to your invocations or applications, which will help you better filter your data.
Tagging Invocations
You can add custom tags to your invocation with the help of static methods of Thundra.Agent.Lambda.Core.InvocationSupport object. These are the methods you can find in the InvocationSupport class.
Searchable Invocation Tags
For now, only primitive String, Number, and Boolean tag values can be searched. Other complex tag values (List, Set, Map, Object, etc.) cannot be searched, but can be seen in an invocation’s details.
Shown below is theInvocationSupport's programmatic tag API:
InvocationSupport.cs
1
public static string InvocationId;
2
public static Dictionary<string, object> GetTags();
3
public static void SetTag(string key, object value); 
4
public static object GetTag(string key);
5
public static void SetError(Exception error);
6
public static Exception GetError();
7
public static void ClearTag(string key);

The example below shows an usage of the InvocationSupport class:
1
using Thundra.Agent.Lambda.Core.InvocationSupport;
2
​
3
...
4
​
5
Console.WriteLine(InvocationSupport.InvocationId);
6
​
7
InvocationSupport.SetTag("user-id", 1980);
8
InvocationSupport.SetTag("user-name", "Dudley Dursley");
9
InvocationSupport.SetTag("is-muggle", true);
10
InvocationSupport.SetError(new UserException("Muggles not allowed"));

Set error to manually created OpenTracing Span
Thundra.Agent.Lambda.Core.SpanSupport tags a custom span that is created via OpenTracing API as erroneous. To learn more about how to create custom spans in order to further your monitoring experience, visit the Enrich Tracing page.
1
using (IScope updateEntityScope = 
2
       GlobalTracer.Instance.BuildSpan("UpdateEntity")
3
       .StartActive(finishSpanOnDispose: true))
4
{
5
  try 
6
  {
7
    DoRiskyThings();
8
  }
9
  catch(Exception e)
10
  {
11
    SpanSupport.SetError(updateEntityScope.Span, e);
12
    throw e;
13
  }
14
}
