Session data not available on console for custom code traces

[jbatra-umeey]

Description

There are no session data details available for custom log

Reproducing the issue

Add a custom code trace like the one below :

FIRTrace *traceObject = [[FIRPerformance sharedInstance] traceWithName:@"testing_code_trace"];
[traceObject start];

• Run the code to send a trace multiple times

• Go to firebase console -> Performance tab -> custom traces

Expected Output : You should be able to view testing_code_trace log with session data

Actual Output : There is no session data available for the log

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

Hello @jbatra-umeey, I suspect that your session data is less than 1%. Note that the default sampling rate for sessions is 1%, therefore, to have a single visible session, your app needs to generate at least 100 sessions. After generating enough sessions, the random sampling of these user sessions will be displayed in the console.

I'll now be closing this ticket, but feel free to comment if the issue persists or if you have questions.
