I have configured my OpenTelemetry agent to instrument the MySQL database my PHP application uses. Next, I followed the install process for the PHP agent to collect traces. My application is being detected in APM, and MySQL shows up as an inferred service in APM, so far so good. When I open Database Query Performance to analyse the queries being executed against my database, however, Splunk claims it cannot display any query data, no matter how large I make the time window.
Yet, when I look at the traces of my application, Splunk is able to see the content of the query spans and their latency. I'm having difficulty understanding why no data is flowing into the Database Query Performance while everything seems to be configured well. Is this feature simply not enabled for trial users?
