Outputs

Splunk

Nuget Package: Spotsoft.Diagnostics.EventFlow.Outputs.Splunk

This output writes data to a Splunk HTTP Event Collector (HEC). Here is an example showing all possible settings:

Field	Values/Types	Required	Description
type	"SplunkOutput"	Yes	Specifies the output type. For this output, it must be "SplunkOutput".
serviceBaseAddress	string	Yes	Base address for the Splunk HTTP Event Collector (HEC) (excluding the API URI e.g. services/collector/event/1.0).
authenticationToken	string	Yes	Defines the HEC token as configured in Splunk. This token can be used to configure the default index, source and sourcetype associated with all events which use it.
host	string	No	The host associated with the events. If left blank this will default to the name of the server which is executing the process using EventFlow.
index	string	No	The Splunk index where the event will be stored. Leave blank unless you specifically want to override the default index associated with the HEC token.
source	string	No	The Splunk source associated with the event. Leave blank unless you specifically want to override the default source associated with the HEC token.
sourcetype	string	No	The Splunk source type associated with the event. Leave blank unless you specifically want to override the default source type associated with the HEC token.
ignoreSslCertificateErrors	boolean	No	When set to true can be used against a Splunk HEC with a self-signed SSL certificate (only recommended for testing purposes).
maxRetryAttempts	integer	No	Maximum number of attempts to call the Splunk HEC API if it returns a server error HTTP Status Code (i.e. >= 500). This uses an exponential backoff algorithm.

Splunk Dashboard

The events might end up looking something like this on the Splunk dashboard:
