Accessing system-wide performance metrics (like com.oculus.ovrmonitormetricsservice)

I’m developing an internal Kotlin app for Meta Quest that reports headset performance data to our servers.

When running as a regular app, I can’t access the same system-wide metrics that com.oculus.ovrmonitormetricsservice logs every second.
From adb shell logcat I can see the data, but from inside the app I get nothing — logcat access and /proc reads are restricted.
I’ve also tried reading from Linux system files and running shell commands, but due to Android sandboxing I only get metrics for my own app process.

Is there any supported way (API, permission, intent, or service binding) to access those metrics from a normal app, or is it limited to system-signed packages?
