# Metric data does not flow into Splunk despite setting up HEC Connection

### Issue <a href="#issue" id="issue"></a>

Customers setting up an HEC connection <https://docs.splunk.com/Documentation/Splunk/8.2.4/Data/UsetheHTTPEventCollector> with Spinnaker Logging may encounter an issue where data is not being pushed to the connector

### Cause <a href="#cause" id="cause"></a>

HEC connector with default ports uses 8088 or 8089 depending on the Splunk version by default. This will happen if you do not configure a TCP listener, and can cause issues in Splunk with attaining data if the port is already in use
