It is recommended that async mode is set in NLog configuration. In async mode the log entries are sent in batches.

Resolving AuthToken

It is highly recommended that the AuthToken value is resolved from a secrets vault rather then NLog.config. You can extend this library and write a custom AuthToken resolution method in InitializeTarget(). Unfortunately, NLog does not support "MethodPointer" configuration parameter types.

Sample NLog.config

The required parameters are

Optional parameters are

  • ignoreSSLErrors - False by default. If True, ssl errors are ignored when posting to the HEC endpoint
  • timeout - # of milliseconds to wait before aborting a POST to HEC endpoint. Default is 30000 (30 seconds).

Keep in mind that the timestamp must be sent along with the log entries. The library will set the timestamp to the current time (DateTime.Now) so ensure that the time across your servers is synchronized.
