Error Reporting

Author: Venkata Sudhakar

Google Cloud Error Reporting is a real-time error monitoring and alerting service that automatically aggregates and displays errors produced in your running cloud services. It groups similar errors together into meaningful error groups, making it easy to identify and fix bugs quickly without manually sifting through raw log files.

Error Reporting works with App Engine, Cloud Functions, Cloud Run, GKE, Compute Engine, and any environment where you write error logs to Cloud Logging. It parses stack traces from logs and groups errors by their call stack signature. When a new error type appears, Error Reporting sends alerts to your team via email or PagerDuty, helping you catch regressions for new errors quickly.

The below example shows how to report errors to Cloud Error Reporting from a Python application using the Cloud Error Reporting client library.

It gives the following output,

Exception reported to Cloud Error Reporting
Customer error reported

# In Cloud Console - Error Reporting dashboard:
Error: ZeroDivisionError: division by zero
  File "app.py", line 8, in main
    result = 10 / 0
Occurrences: 1  |  First seen: 2024-01-15  |  Last seen: just now
Status: OPEN

The below example shows how to configure Error Reporting for a Java application using the Logback logging framework, which automatically captures and forwards exceptions to Cloud Error Reporting via Cloud Logging.

import com.google.cloud.logging.Logging;
import com.google.cloud.logging.LoggingOptions;
import com.google.cloud.logging.Payload.StringPayload;
import com.google.cloud.logging.LogEntry;
import com.google.cloud.logging.Severity;

public class ErrorReportingExample {
    public static void main(String[] args) {
        // Error Reporting reads from Cloud Logging automatically.
        // Log errors with ERROR or CRITICAL severity and a stack trace.
        try {
            processPayment(null);
        } catch (Exception e) {
            // When running on GCP (GKE, Cloud Run, App Engine),
            // simply logging the exception at ERROR level is enough.
            // Error Reporting picks it up and groups it automatically.
            java.util.logging.Logger logger =
                java.util.logging.Logger.getLogger("my-service");
            logger.severe("Payment failed: " + e.toString());
            // Stack trace is automatically captured and parsed.
        }
    }

static void processPayment(String orderId) {
        if (orderId == null) {
            throw new IllegalArgumentException("Order ID must not be null");
        }
    }
}

It gives the following output in the Cloud Error Reporting console,

Error Group: IllegalArgumentException: Order ID must not be null
  at ErrorReportingExample.processPayment(ErrorReportingExample.java:24)
  at ErrorReportingExample.main(ErrorReportingExample.java:12)

Occurrences: 1
Service: my-service
Severity: ERROR
Status: OPEN
Alert sent: [email protected]

Key Features of Cloud Error Reporting:

Automatic grouping - Similar errors are grouped by call stack, so 1000 occurrences of the same bug appear as a single error group rather than 1000 separate entries.

Resolution tracking - Mark errors as RESOLVED or ACKNOWLEDGED to track fix progress. Errors reopen automatically if they recur after being resolved.

Alerting - Configures alerts when new error types first appear in your service, sending notifications via email, PagerDuty, or other channels.
