Use Cloud Logging's query to count errors and manually check the rate periodically.

Create a log-based metric for error counts and another for total requests, then set an alert on the ratio.

Your application is running on Compute Engine and you have noticed that memory usage is consistently high. You need to determine which part of the code is responsible for the memory consumption. What should you do?

Use Cloud Profiler to capture a memory profile and analyze the heap allocations.

Run a load test and use Cloud Trace to analyze memory usage during the test.

Add logging statements to print memory usage at various points in the code.

Use Cloud Monitoring to view memory utilization of the VM and correlate with application logs.
