2.2.0 [Release date: 2021-05-19]

GitHub Releases

Added

  • Support cost control configured in the Dynatrace UI.
  • It is possible to get the duration from an IAction.
  • An IAction can be canceled.
    Canceling an IAction is similar to leaving it, without reporting it.
  • Requests to Dynatrace can be intercepted to add custom HTTP headers.
  • Excplicit support for additional .NET target frameworks.
    • .NET Core 2.1 and 3.1
    • .NET Standard 2.1
    • .NET Framework 4.5.1, 4.5.2, 4.6.1, 4.6.2, 4.7.1, 4.7.2 and 4.8

Changed

  • Provide a more reliable way to determine monotonic timestamps.
  • Fix potential endless loop in beacon sending, when lots of data is generated in a short period of time.
  • Update testing dependencies to latest possible version.

2.1.0 [Release date: 2020-11-16]

GitHub Releases

Added

  • DynatraceOpenKitBuilderVB and AppMonOpenKitBuilderVB are added to workaround an ambiguity error affecting VisualBasic developers. Since VB is case insensitive AbstractOpenKitBuilder.WithModelID(string) and AbstractOpenKitBuilder.WithModelId(string) are considered the same methods.
    This workaround is marked as obsolete and will be removed when the obsolete method AbstractOpenKitBuilder.WithModelID(string) is removed.
  • Overloaded IAction.ReportValue(string, long) method for reporting 64-bit integer values.
  • Overloaded ISession.ReportCrash(Exception) as convenience method for reporting an Exception as crash.
  • Overloaded IAction.ReportError(string, int) method for reporting an integer error code without description.
    The old IAction.ReportError(string, int, string) has been deprecated in favor of the new one.
  • Overloaded IAction.ReportError(string, Exception) for reporting caught exceptions as error.
  • Overloaded IAction.ReportError(string, string, string, string) for reporting generic errors to Dynatrace.

Changed

  • Fix issue with sessions being closed after splitting. This happened because OpenKit was sending an end session event right after splitting. New behavior is to only send the end session event if explicitly requested via the Session.End() method and only for the active session.
  • IdentifyUser can be called with null or an empty string.
    This simulates a log off event and no longer re-applies the user tag on split sessions.
  • Improve handling of client IP in combination with server-side detection.
  • Fix in JsonResponseParser to parse correct key for max session duration.
  • Fix multithreading issues in SessionProxy, leading to a potential NullReferenceException.
  • Fix potential memory leak for very short-lived sessions in SessionProxy.

2.0.0 [Release date: 2020-06-24]

GitHub Releases

Added

  • Support for parsing JSON
  • Technology type support for error and crashes
  • Support for session splitting. Sessions are split transparently after either the maximum session duration, the idle timeout or the number of top level actions are exceeded. Session splitting is only applicable, if it is also supported by Dynatrace. The internal details are described here.
  • Re-apply user tag on split sessions.

Changed

  • On OpenKitBuilder creation device ID is parsed from the given string. Non-numeric device IDs are hashed to a corresponding numeric value. Internally a numeric type is used for the device ID.
  • Response code is now a parameter of WebRequestTracer's stop method. Existing methods for stopping and setting the response code have been deprecated.
  • Fix missing parameter in request URL when requesting a new session.
  • WithModelID on AppMonOpenKitBuilder / DynatraceOpenKitBuilder was deprecated. WithModelId should be used instead.
  • Setting property ApplicationVersion on IOpenKit was deprecated and calls to this setter are ignored. WithApplicationVersion on AppMonOpenKitBuilder / DynatraceOpenKitBuilder should be used instead.
  • Add OpenKit.createSession overload without IP address parameter.
    The IP address is determined in this case on the server side.
  • Fix coveralls.io build
  • Fixed issue with reporting localized beacon data
    Integer and floating point numbers might have been reported with the thread's locale causing issues with session properties.
  • Reporting a crash causes a session split, which is transparently handled

Improvements

  • Reformatted text files to unix style line endings.

1.4.0 [Release date: 2019-02-14]

GitHub Releases

Added

  • Package distribution via NuGet Distribution via GitHub releases changed as well, since a single zip file is deployed.

Changed

  • Application ID and Visitor ID are correctly encoded for special characters The encoding is a percent-encoding based on RFC 3986 with additional encoding of underscore characters.
  • OpenKit assemblies are strongly named
  • Fixed problem with infinite time sync requests This problem occurred mainly in AppMon settings.

1.3.0 [Release date: 2018-10-25]

GitHub Releases

Added

  • Device ID can be specified as String in addition to long
    This allows to send UUIDs or other specifiers
  • Standalone web request tagging
    A WebRequestTracer can also be obtained from a Session

1.2.0 [Release date: 2018-09-14]

GitHub Releases

Added

  • New project for .NET Standard 2.0
  • New project for UWP and PCL 4.5 target 111
    For those two projects, self signed SSL certificates are not manageable by OpenKit .NET.
  • Server overload prevention
    Additional HTTP 429 response code handling

Changed

  • Fix wrong Session start time
  • Fix wrong device ID in web requests
  • Add Thread identifier to log output
    This makes the log output similar to the Java/Native implementation

Improved

  • OpenKit internal version handling

1.1.0 [Release date: 2018-07-20]

Changed

  • Replace DotNetZip library with .NET builtin gzip library
  • Internally used sleep method does sleep in small intervals
    .NET Core 1.X cannot interrupt a thread
  • Further actions on already left/closed OpenKit objects are no longer possible
    Calling the methods is still allowed, but nothing is reported to the backend
  • HTTPClient checks response type from server when parsing
  • Enhanced null checks in public interface implementation
    No exception are thrown, if nulls are passed via public interfaces
  • OpenKit internal threads are background threads
  • Enhanced state transition in internal state engine
  • Thread IDs are reported as positive 32-bit integers only
    This is handled by masking out the sign bit
  • WebRequestTracer's start time is initialized in constructor
  • Advanced URL validation when tracing web requests
    The URL must have the form
    <scheme>://<any character>[<any character>]*
    Where scheme must be as defined in RFC 3986

  • Major logging improvements (more and better messages)
