Introduction

In the realm of cloud computing, logging is a crucial aspect of monitoring and troubleshooting applications. Google Cloud Platform (GCP) provides a robust logging service that allows users to collect, store, and analyze log data from various sources. However, by default, all logs in GCP are displayed with a DEFAULT severity level, which can make it challenging to identify critical issues. To address this limitation, we propose adding log severity mapping to GCP, similar to what is used in other cloud providers. In this article, we will explore the concept of log severity mapping, its benefits, and how it can be implemented in GCP.

What is Log Severity Mapping?

Log severity mapping is a mechanism that assigns a severity level to each log message based on its content and context. This allows users to quickly identify critical issues, such as errors and warnings, and prioritize their attention accordingly. Log severity mapping is commonly used in cloud providers, including Amazon Web Services (AWS) and Microsoft Azure, to enhance log visibility and analysis.

Benefits of Log Severity Mapping

The benefits of log severity mapping are numerous:

Improved log visibility: Log severity mapping enables users to quickly identify critical issues, such as errors and warnings, and prioritize their attention accordingly.
Enhanced troubleshooting: By assigning a severity level to each log message, users can quickly identify the root cause of an issue and take corrective action.
Better resource allocation: Log severity mapping helps users allocate resources more effectively, as they can focus on critical issues that require immediate attention.
Increased productivity: By reducing the time spent on troubleshooting and issue resolution, log severity mapping can increase productivity and efficiency.

Log Severity Levels

Log severity levels are typically categorized into the following levels:

DEBUG: Low-level messages that provide detailed information about the application's execution.
INFO: General information messages that provide context about the application's behavior.
WARNING: Messages that indicate a potential issue or anomaly.
ERROR: Critical messages that indicate a problem or failure.
CRITICAL: High-priority messages that require immediate attention.

Implementing Log Severity Mapping in GCP

To implement log severity mapping in GCP, we can use the following approach:

Define log severity levels: Define the log severity levels that will be used in GCP, such as DEBUG, INFO, WARNING, ERROR, and CRITICAL.
Assign severity levels to log messages: Assign a severity level to each log message based on its content and context.
Use a log severity mapping table: Create a log severity mapping table that maps each log message to its corresponding severity level.
Integrate with GCP logging: Integrate the log severity mapping table with GCP logging to display log messages with their corresponding severity levels.

Example Use Case

Suppose we have a web application that uses GCP logging to collect log data. We want to implement log severity mapping to enhance log visibility and analysis. We define the following log severity levels:

DEBUG: Low-level messages that provide detailed information about the application's execution.
INFO: General information messages that provide context about the application's behavior.
WARNING: Messages that indicate a potential issue or anomaly.
ERROR: Critical messages that indicate a problem or failure.
CRITICAL: High-priority messages that require immediate attention.

We assign a severity level to each log message based on its content and context. For example:

DEBUG: "User logged in successfully."
INFO: "User attempted to access a restricted page."
WARNING: "Potential security vulnerability detected."
ERROR: "Database connection failed."
CRITICAL: "System crashed due to hardware failure."

We create a log severity mapping table that maps each log message to its corresponding severity level. We then integrate the log severity mapping table with GCP logging to display log messages with their corresponding severity levels.

Conclusion

Log severity mapping is a powerful mechanism that enhances log visibility and analysis in GCP. By assigning a severity level to each log message, users can quickly identify critical issues and prioritize their attention accordingly. In this article, we explored the concept of log severity mapping, its benefits, and how it can be implemented in GCP. We also provided an example use case to illustrate the implementation of log severity mapping in a real-world scenario. By implementing log severity mapping in GCP, users can improve their log visibility and analysis capabilities, leading to increased productivity and efficiency.

Future Work

In the future, we plan to extend the log severity mapping feature to support additional cloud providers, such as AWS and Azure. We also plan to enhance the log severity mapping table to support more advanced features, such as log filtering and aggregation.

Appendix

The following is a sample log severity mapping table that maps each log message to its corresponding severity level:

Log Message	Severity Level
User logged in successfully.	DEBUG
User attempted to access a restricted page.	INFO
Potential security vulnerability detected.	WARNING
Database connection failed.	ERROR
System crashed due to hardware failure.	CRITICAL
