As the system becomes more complex, the log system becomes more and more important. In traditional logging systems, each log has an automatically generated unique ID, usually called a log ID. It can help us track and locate logs, troubleshoot problems, etc.
This article will introduce how to implement a simple log ID in Golang.
- What is log ID
Log ID is a unique identifier used to distinguish different logs. Normally, a log ID consists of a string of numbers and letters with a fixed length, which can be a 32-bit or 64-bit hexadecimal number, for example: c1a2b3e4-d5f6-4f3d-b2d3-2c1a5b9d9e8f.
Using log IDs has many benefits, such as:
- It can help quickly locate and troubleshoot problems
- It can record all the logs in an operation for easy search and analysis
- Different logs can be classified into the same event
- Implementing a simple log ID
In Golang, we You can use the UUID library to generate unique IDs. UUID (Universally Unique Identifier) is a unique identifier generated within a certain time and space range by a specific algorithm. Its length is fixed, usually 36 characters (including hyphens).
Golang provides a standard library uuid
for generating UUID. The code below demonstrates how to use the uuid
library to generate a random UUID string.
package main import ( "fmt" "github.com/google/uuid" ) func main() { uuid := uuid.New().String() fmt.Println(uuid) }
Code output:
60e396aa-525b-4ce5-b8a2-8ca54507769a
Every time it is run, a new UUID can be generated.
In actual use, we can use UUID as the log ID. This ID is unique and random enough to avoid duplicate IDs.
- Encapsulate log ID
In order to facilitate use and management, we can encapsulate the process of generating log ID into a function. The following is a simple implementation:
package main import ( "fmt" "github.com/google/uuid" ) func genLogID() string { return uuid.New().String() } func main() { logid := genLogID() fmt.Println(logid) }
Here we define a function genLogID()
to generate a random UUID string. By calling this function, you can get a new log ID.
- Application scenarios of log ID
Log ID can be applied to various log systems, such as:
- In distributed systems Logs: In a distributed system, since different services may generate a large number of logs, log IDs can help quickly distinguish different logs, locate and troubleshoot problems.
- Big data log analysis: When performing big data log analysis, log ID can aggregate different logs into the same event to facilitate subsequent processing and statistics.
- Security audit log: In the security audit system, each operation will generate a unique log ID, which can be used for subsequent auditing and inspection.
In short, log ID has a wide range of application scenarios and can help us better manage and analyze log information.
- Summary
This article introduces how to implement a simple log ID in Golang. By using UUID as the log ID, the uniqueness and randomness of the ID can be guaranteed, which facilitates our log management and analysis.
When we develop large systems, don’t forget the importance of the logging system, and always maintain clear log output and appropriate log levels. Log ID can help us better manage and analyze log information and improve the maintainability and reliability of the system.

Developers should follow the following best practices: 1. Carefully manage goroutines to prevent resource leakage; 2. Use channels for synchronization, but avoid overuse; 3. Explicitly handle errors in concurrent programs; 4. Understand GOMAXPROCS to optimize performance. These practices are crucial for efficient and robust software development because they ensure effective management of resources, proper synchronization implementation, proper error handling, and performance optimization, thereby improving software efficiency and maintainability.

We need to customize the error type because the standard error interface provides limited information, and custom types can add more context and structured information. 1) Custom error types can contain error codes, locations, context data, etc., 2) Improve debugging efficiency and user experience, 3) But attention should be paid to its complexity and maintenance costs.
