Devops Best Practices for Observability

Imagine one night you receive a notification from your team member that a critical production problem has caused chaos in your application.

There is a sudden drop in sales as customers are unable to access the application and reporting issues relating to the same.

Now, when you reach the office to fix the issue, you demand the team to run through all the files.

But, when the team members try to go through all the log files, they find that you have access to only a few event records as all the files are scattered, metrics are confusing as well as traces are difficult to track down. Hence, you face the struggle to find the actual cause of the production issue.

Now, what if you had invested in the concept of observability?

Observability is not just a simple term, but a whole concept that consolidates all your logs, metrics, and distributed tracing systems into one place for quick analysis and troubleshooting.

This practice allows DevOps teams to discover the root cause of failure, measure the internal processes’ health status, identify flaws, and take corrective actions.

By examining the logs and data, you may determine what went wrong with the application and when, having an effective observability system in place allows DevOps teams to solve issues more quickly, maximize performance, and provide better user experiences.

In fact, observability solutions can be very helpful for the DevSecOps lifecycle and IT operations (AIOps).

Let us learn more about the concept of observability, its three pillars, and best practices for each pillar.

The Observability Pillars

The observability concept works on three pillars, i.e., logs, metrics, and distributed traces, using which any organization can better maintain its performance and achieve its goals.

Logs

These are event records stored by organizations in plain text for future reference and analysis.

These include information about every event that occurred in a specific period.

With a centralized log management system, businesses can view all the events and errors collected from different sources in one place and timely analyze as well as troubleshoot issues.

Further, the log formatting standards like JSON, make it simpler for system administrators and coders to analyze all the log data programmatically.

By employing these right tools, businesses can track all the issues and anomalies in real time.

Metrics

Metrics are attributes-based numerical values that show how well a specific system component is performing.

For example, application metrics include error rates, throughput, and response time.

With the help of these metric insights, businesses can track how well a software application is performing and serving its purpose.

Similarly, the infrastructure metrics include memory usage, CPU usage, network latency, and more responsibility for monitoring the health and performance of each hardware and software component.

Business metrics are another example used by organizations to monitor key objectives and outcomes of a business.

It is easier to prioritize monitoring efforts when you know which key metrics are most important for the system’s stability and success.

Also, you can even set alerts based on predefined thresholds or patterns in metrics that help proactively identify and resolve problems before they escalate.

Traces

With distributed tracing, IT professionals can easily visualize how each service is connected with one another and how the flow of requests moves through the entire application.

With the help of these insights, users gain clear visibility and a better understanding of pathways, requests, transactions, and responses, which help in better application performance management.

By tracing each and every component, the user can quickly identify the bottlenecks and latency issues in real-time time, further helps in performance optimization and improving user experience.

Best Practices for Each Pillar

Here are a few DevOps best practices that must be followed for each pillar –

Logs:

1. Choosing the right log management tool – There are several open-source and commercial log management tools available in the market that one can choose from for logging monitoring.

Depending on your budget and scalability requirements, try to invest in a tool that meets your needs. Open-source log management solutions and flexible and can be easily customized but demand more maintenance.

On the other hand, commercial log management tools come with a wide range of features and support services but are a bit pricey in comparison to other tools.

2. Log Rotation Policy Enforcement – By setting up log rotation policies, organizations can better manage the disk spaces and avoid issues.

With regular rotation and log archiving, businesses can prevent log files from taking up too much of disk space and maintain better system performance.

3. Leverage log analysis tools – Investing in some of the best log analysis tools will provide better visibility into big data, help identify trends and anomalies in real-time as well as troubleshoot issues faster.

These tools include pattern recognition and anomaly detection features that save time and allow businesses to take preemptive actions before the problem escalates.

Metrics:

1. Define ownership and documentation – Assign DevOps teams or individual responsibility for each metric with complete ownership and documentation. With this practice, you can ensure better clarity and consistency across the organization.

2. Standardize metric collection – Set standardized practices that address the purpose of metrics, naming format, and classification which will help team members gain more clarity into the processes.

Further, standardizing metric collection makes it easier for DevOps to compare different metrics, analyze, and troubleshoot issues.

3. Dashboards and Visualizations – Using the dashboards and data visualization, DevOps can easily monitor the different metrics, their trends, issues, and abnormalities in real time.

Thus, allowing them to take the right action at an early stage and prevent the issue from escalating any further.

Traces:

1. Select a distributed tracing solution – Choose from a wide range of distributed tracing solutions but make sure to invest in the one that integrates well with your existing tools.

Compare the different sets of tools depending on their ease of integration, scalability as well as compatibility criteria for smooth operations.

2. Identify critical service calls – It is essential to identify the important service calls and transactions that play a key role in system performance.

By tracing these functionalities, businesses can use resources as efficiently as possible and optimize performance as well as user experience.

3. Utilize trace data for analysis – Transaction and Service call tracing helps in incident management.

IT Teams gain clear visibility into the flow of requests that help identify the root cause of potential issues and bottlenecks in the systems.

Further, with the help of these insights, businesses can work on failure points and prevent losses.

Putting it all Together

The three pillars of Observability, i.e., logs, metrics, and traces have their own roles and functionalities.

Each of these pillars when used together can help provide a comprehensive picture of your system’s health and enable teams to strategize an action plan accordingly.

With logs, users can keep an account of events that happened at a specific period which can be used for troubleshooting.

With metrics, users can analyze the trends and patterns as well as measure resource utilization across the entire system.

Lastly, the trace data provides a clear path of how the transactions and requests move through the system.

Together, they help teams uncover problems, comprehend system behavior, and make better decisions that raise dependability and performance.

An observability pipeline is a stream processing engine that ensures all data is gathered efficiently, processed, and transformed into insightful data which is later presented to the stakeholders in a visual manner for quick analysis and decision-making.

Observability pipelines enable cost-effective management of observability data for enterprises, as well as regulatory compliance.

It provides a centralized platform for addressing issues and responding to them.

Without a robust observability pipeline, teams may find it difficult to efficiently monitor and manage complex systems.
