No log data appears in the UI

Problem

After enabling log management, no data appears in your Logs UI after about five minutes.

Solution

If no data appears after you send some log payloads and wait about five minutes, try the following:

Logs troubleshooting Comments
Access to data See Factors affecting access to features and data.
Compatibility Make sure you've installed a compatible log forwarding plugin.
Status codes

Check the response status code being returned from the New Relic log collection endpoint. For example, you might see:

HTTP Error 403: Forbidden. Review your license key.

This error means that you're using an invalid security key. New Relic requires an Insights API Insert key or license key to enable log shipping. An HTTP 202 response is a success.
Errors

Run a query using the NrIntegrationErrors NRQL event to see if any errors are related to logging. For example, look for messages like:

Error parsing JSON payload
Checking for Data Try querying the Log data type using Insights. For example, you can use a NRQL query to look at everything in the Log eventType. If no data appears in Insights, then no data will appear in the Logs UI. 
SELECT * FROM Log

For information on querying in general, see Query your data.
