What are some best practices for monitoring and logging microservices?

由人工智能和领英社区提供技术支持

Microservices are a popular architectural style for building scalable and resilient applications that consist of small, independent, and loosely coupled services. However, managing and troubleshooting microservices can be challenging, especially when they are distributed across multiple environments and communicate through various protocols. That's why monitoring and logging are essential practices for ensuring the performance, reliability, and security of your microservices. In this article, we will discuss some best practices for monitoring and logging microservices, such as:

1 Define key metrics and alerts

Monitoring microservices means collecting and analyzing various metrics, such as response time, throughput, availability, error rate, resource utilization, and service dependencies. You should define the key metrics that reflect the health and performance of your microservices, and set up alerts and dashboards to visualize and notify you of any anomalies or issues. You should also use tools that support distributed tracing, which allows you to track and correlate requests across multiple services and identify the root cause of problems.

Among microservices you also want to differentiate the Client vs Service metrics, it's important to own the client side metrics as well, so you have a better picture to understand the client behavior vs network outage. Another big elephant in the room is the fault tolerance of your monitoring system, would you be alerted when the monitoring system itself hit incidents.

2 Implement structured and consistent logging

Logging microservices means capturing and storing the events and messages that occur within and between your services, such as requests, responses, errors, exceptions, warnings, and debug information. You should implement structured and consistent logging, which means using a common format and level for your log messages, and including relevant context and metadata, such as timestamps, service names, request IDs, and user IDs. You should also use tools that support centralized logging, which allows you to aggregate and query your logs from a single place and filter and analyze them by various criteria.

3 Adopt the 12-factor app principles

The 12-factor app is a set of principles and best practices for building modern, cloud-native applications that are portable, scalable, and maintainable. When it comes to monitoring and logging microservices, some of the relevant principles include treating logs as event streams, storing configuration settings in the environment, and using declarative formats for setup automation. This means that your microservices should not write logs to files or local storage but instead stream them to a standard output or log aggregation service. Additionally, configuration settings and secrets should not be embedded in code or files; rather, environment variables or external services should be used to inject them dynamically and securely. Moreover, manual or ad hoc scripts or commands for deployment or provisioning should be replaced with declarative formats like manifests or templates that can automate and standardize these processes.

4 Follow the best coding practices

Monitoring and logging microservices depend on the quality and consistency of your code, thus you should adhere to the best coding practices. This includes proper error handling and logging, with clear and meaningful names for variables, functions, classes, files, and services. Additionally, code reviews and testing should be done regularly to ensure functionality, reliability, and security. These practices are not only important but also necessary to improve the visibility, observability, and traceability of microservices as well as their performance, reliability, and security.
