DevOps monitoring: The Why, What, and How of DevOps monitoring
In 2017, Amazon faced an unfortunate four-hour outage, causing S&P 500 companies to lose $150 million. What was the cause? An erroneous command removed more servers than intended, causing system downtime. Although downtime is not an alien topic for developers, its impact can be deeply felt. Gartner estimates the average cost of downtime to be as high as $5600 per minute, which may build up to over $300k per hour. These are definitely scary numbers for any organization.
But there’s no need to panic just yet!
Taking a few proactive and calculated steps can minimize the impact of downtime. A list of best practices for achieving this can include reviewing the test server backups, infrastructure maintenance, regular monitoring, and maintaining the stability and security of your devices.
Monitoring as a development practice is essential – not just for preventing downtimes. It brings multiple other benefits to an organization and improves the processes for your development teams.
What is DevOps monitoring?
Monitoring in Devops covers a diverse range of processes, including planning, development, testing, deployment, and operations. It offers a comprehensive and real-time view of the status of the production environment with insights into applications, infrastructure, and services. Collecting data from logs and metrics allows you to observe performance and compliance at each stage of the SDLC pipeline.
How is monitoring different from telemetry?
When a monitoring tool collects measurement data, telemetry is responsible for representing this data. It performs the function of an agent providing specific monitoring data and real-time alerts for important events and crucial information related to resource utilization. DevOps requires continuously measuring application health and performance, and telemetry always provides these metrics on the dashboards.
What are the different types of monitoring in DevOps?
An organization that relies on Information Technology for delivering its products and services requires setting up and maintaining an IT infrastructure. This infrastructure includes everything from networks, servers, computer hardware/software, data centers, and storage. By monitoring the IT infrastructure, you can collect and examine information obtained from it and use the data to enhance final outcomes. It includes monitoring hardware, application, OS, and the network. Popular infrastructure monitoring tools include Prometheus, ManegeEngine, and Solarwinds.
Application performance monitoring
By monitoring an application, you can gain runtime metrics on how your application performs, including app uptime, security and log monitoring, and overall app performance. APM tools such as DataDog, Uptrends, and Splunk are widely used to generate transaction volume and time metrics, API responses, backend application health, and more. Typically, these metrics are delivered after evaluating the application performance and overall infrastructure in the form of graphics and statistics.
It tracks everything about the network, including routers, servers, VMs, firewalls, etc. Network monitoring is responsible for identifying faults, measuring the performance of these elements, and optimizing their functionality. A dynamic network monitoring system can help avoid downtimes and failures before affecting performance. A list of popular tools includes Cacti, Spiceworks, and Wireshark.
What are the best DevOps monitoring strategies?
Decide what needs monitoring
Before going into details, it is important to know what needs to be monitored to make the most of your efforts. The monitoring goals should focus on the server’s health, vulnerabilities, user activity, and application log output.
Set fixed development goals
These goals are indicative of how well your DevOps monitoring strategies are working. It also helps obtain insights into how efficient your workflow is and how well your teams perform. A proven way of ensuring these outcomes is to record the duration of each sprint and the average time taken to identify, document, and fix bugs. Consider using machine learning to effectively automate configuration tasks and save significant time.
Enable user activity monitoring
One of the essential monitoring types, user activity monitoring, can help mitigate cyberattacks and potential threats to the system. It is important to track unusual requests, multiple login attempts, or log in from unknown devices and suspicious activities like a developer accessing the admin account. By monitoring the user activity, you can ensure that only the authorized users have entered the system and make your application more reliable for your users.
Pick the right monitoring tools
Choosing a monitoring tool that meets your goals and requirements starts with an evaluation process. It primarily involves understanding the functionality of each tool and learning if the tool is best suited for application or infrastructure monitoring to make the right decision.
Why is DevOps monitoring important?
Proper system monitoring provides valuable insights, enabling you to view every component in your application stack with the help of API-driven code. Also, when code hooks are embedded into the application logic, it augments the monitoring process.
Devops monitoring is inherently proactive, and as a result, it identifies the gaps and opportunities to improve the application performance before the bugs are visible. Monitoring also improves the DevOps toolchain by highlighting where automation may be beneficial. It encourages DevOps teams to use third-party tools for deployment, ticketing, altering, and more, offering more advanced complex application features.
Here are three common but significant benefits of DevOps monitoring:-
Brings automation for collaboration
The core principle of DevOps is improving collaboration between the development and operations teams. However, if there is an absence of integration between tools, coordination between teams may hit a wall. Therefore, you can leverage automation to enable a unified view of the entire development pipeline or track commits and pull requests to make records of Jira issues and notify the development team on their preferred communication channel.
Improves visibility for constant code changes
The complexity of a production environment increases as CI/CD enables developers to make frequent changes to their code. Moreover, micro-services and micro frontends have introduced thousands of moving parts in a workflow, where every part operates at a different scale and observes different latency and redundancy. As a result, complete visibility into the ecosystem is crucial for teams to mend any damage done to the user experience in real time.
Enables implementation of shift-left testing
Shift-left testing can improve quality, reduce test cycles, and decrease errors when performed at the beginning of the lifecycle. It also makes it easy to streamline monitoring the health of your pre-production environments and implement it before and more often. Early monitoring also helps assess how the application behaves by tracking user interactions essential for maintaining performance and availability before the application is deployed in production.
Use cases of Devops monitoring
There’s no doubt that DevOps monitoring brings significant benefits to any organization. However, implementing it effectively will ensure complete success. Here are 5 use cases of DevOps monitoring that can be leveraged by organizations without requiring their development teams to go out of their way to achieve success.
Monitoring Git workflows
When multiple developers handle the same project functionality, there are higher chances of recurring codebase conflicts. Git helps manage and resolve conflicts, which also includes commits and rollbacks. Monitoring Git workflows enables you to keep track of conflicts and maintain consistent progress in your project.
Microservices applications require distributed tracing to streamline monitoring and debugging processes. When your teams understand how the applications interact with each other through APIs, it becomes easier to detect and repair issues. Moreover, distributed tracing is also crucial in optimizing app performance and identifying bottlenecks.
Continuous Integration/Deployment logs
With the growing adoption of CI/CD pipelines in development ecosystems, monitoring them is crucial for a healthy system. CI logs inform you about the errors or warnings in your code builds. Monitoring them ensures the identification of potential challenges in your build pipeline, so your team can address them on time. Similarly, monitoring CD logs generate reports on the development pipeline’s overall system health and status. It helps you troubleshoot any failed deployments and also repair potential issues.
Configuration management changelogs
Configuration management changelogs offer insights into the system’s health and vital changes. Monitoring these logs will provide you access to changes made to the system – manual and automated, to view unauthorized changes and repair damages.
Code instrumentation is adding code to an application that collects data about its performance and operations route. It is key to tracing stack calls and viewing contextual values. By monitoring the instrumentation results, you can determine the efficiency of your DevOps practices and identify potential gaps that need urgent attention and improvements. It’s also important to detect bugs and enhance testing.
What makes a DevOps monitoring platform ideal?
When choosing a solution for DevOps monitoring, you need to consider features that will allow you to make the most of your investment. More importantly, complex applications need to be updated multiple times a day. Therefore, an advanced monitoring system is vital. Such a system must support Docker, traditional and modern toolsets, and frameworks. It should also have the top programming languages like Ruby, Go, Python, and PHP.
The platform should seamlessly integrate into your workflow and be compatible with the tools your team leverages. They may include, but are not limited to:
