Firebase Performance logs too much when data collection disabled

[xiao99xiao]

• Xcode version: 11.2
• Firebase SDK version: 6.11.0
• Firebase Component: Preformance
• Component version: 3.1.5

Steps to reproduce:

I have isInstrumentationEnabled & isDataCollectionEnabled set to false, then run the app from Xcode in Debug mode, Performance begins infinite logging complaining things like below

[Firebase/Performance][I-PRF100013] Dropping event since data collection is disabled.

One or two logs like that are usually ok. But currently, I got this line log every 1 seconds. Maybe it's because I have a timer that sends a network request every 1 seconds and Performance manages to monitor the request, but then find it should not collect the data, so it complains. Anyway, It makes log console in Xcode completely useless.

Relevant Code:

in func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool

Performance.sharedInstance().isInstrumentationEnabled = false
Performance.sharedInstance().isDataCollectionEnabled = false

I found a few problems with this issue:

• I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.
• This issue does not seem to follow the issue template. Make sure you provide all the required information.

@xiao99xiao Currently these are log messages that are displayed only on one of the higher levels of verbosity. Can you double check if you have a high level of verbosity. Check for environment variable "-FIRInfoEnabled" in your app's scheme definition?

When set to -FIRDebugEnabled, these load of log messages should not be seen.

@visumickey You are right, I set -FIRDebugEnabled and then the log was gone. Even after I removed that flag, the log still stays neat now.
Thanks you so much!
