Why Monitor Microservices?

Reduces and Prevents Microservices Mishaps

Monitoring microservices helps reduce and prevent mishaps before they happen by proactively identifying potential issues and taking corrective actions. 

In a distributed system, a failure or malfunction in one service can have a cascading effect on other services, leading to a system-wide outage. 

By monitoring individual services' performance, health, and interactions, teams can detect anomalies, diagnose root causes, and fix the problem before it becomes critical.

Meeting Your Microservices' SLAs

SLAs define the level of service a customer can expect and establish clear expectations for availability, response time, and other critical metrics. 

To meet SLAs in a microservices environment, monitoring each service's performance and interactions is essential. Failure to meet SLAs can result in lost revenue, damaged reputation, and even legal repercussions.

Monitoring microservices helps to identify and resolve issues before they impact customers or the business. 

By tracking metrics such as response time, error rates, and throughput, teams can proactively detect and address performance bottlenecks or service failures.

Identify Patterns in Monolithic Apps with Microservices Monitoring

In a monolithic application, all the components are tightly coupled, and it is challenging to isolate specific issues. 

However, in a microservices architecture, each service operates independently, and monitoring can help to identify patterns that may be otherwise difficult to notice. 

For example, by tracking metrics like response time and error rates across services, teams can identify patterns of performance degradation or service failures that may indicate a systemic issue.

Microservices monitoring also helps to identify issues with dependencies between services. 

To Optimize End-user Experience

One of the significant benefits of microservices monitoring is the ability to identify and troubleshoot issues quickly. 

By tracking metrics like response time and error rates, teams can detect performance bottlenecks and service failures that can impact the user experience. 

By proactively identifying and addressing these issues, teams can optimize the end-user experience and improve customer satisfaction.

Best Practices for Microservices Monitoring

So, how to monitor microservices? And more importantly, what are some best practices of microservices monitoring that you can leverage?

Monitor what is Inside the Container 

When monitoring microservices, keeping an eye on what's happening inside the container is essential. Containers have become the standard for packaging and deploying microservices, making understanding their work and what's happening inside them crucial.

It lets you identify issues with specific microservices, such as memory or CPU usage. This information is crucial for ensuring that each microservice runs efficiently and performs as expected. 

Monitoring the container can detect problems affecting the entire microservices architecture, such as network latency or data inconsistencies.

Unify Logs, Metrics, and Traces into a Single Event Stream for Effective Monitoring

Unifying logs, metrics, and traces into a single event stream is crucial when monitoring microservices. Doing so provides a comprehensive view of your system's behavior, making detecting and resolving issues quickly easier.
