Today, companies are increasingly adopting DevOps for its continuous integration and continuous delivery approach. In the realm of DevOps, the spotlight is often taken by automation.
That is not surprising. Why? According to the 2019 State of DevOps report by Puppet, DevOps automation has a positive impact on the overall effectiveness of an organization However, perhaps more than automation, DevOps monitoring is yet another crucial element that helps increase awareness during each stage of the delivery pipeline. There are numerous aspects of monitoring that you might want to consider. Like what? What you should monitor, which tools to use, or how to get started with your DevOps monitoring strategy. While monitoring preceded DevOps, DevOps has further transformed the software development process to such an extent that monitoring has to evolve as well. The overall pace of software development has increased with DevOps and teams are now automating integration and testing, and deploying software in the cloud with quick timelines and continuous delivery. With DevOps, there’s more to monitor now, from integration, provisioning, to deployment, teams need to use DevOps monitoring strategies to effectively monitor different aspects of the project. To help you with your DevOps monitoring strategies in a rapidly changing environment, we have created a generic framework to help you understand how to get started, what to monitor, which tools to use for monitoring needs, and where you can consolidate. The first step of effective DevOps monitoring strategies? Determining what you should monitor in your applications. Monitoring targets can be divided into several primary categories, and you will likely want to cover at least one aspect of each category. These categories include: Monitoring development milestones is an indicator of how well your DevOps strategy is working. It is an effective way to gain insights into your workflow and determine how effectively your team is operating. Track the duration of each sprint; the rate at which bugs are identified, documented, and fixed; and the ratio of expected-to-delivered features. Ask questions such as: Consolidate monitoring tools whenever possible to streamline and speed up troubleshooting. Use open-source and open-license agents to extend technology and remain vendor-independent. What else? You can use machine learning technology to automate configuration tasks and save time. Vulnerabilities can be broadly categorized into two parts: known weaknesses or vulnerabilities in an application that are widely known or identifiable via lists maintained by National Vulnerability Database (NVD), and vulnerabilities that occur due to insecure coding practices, insecure design, or insecure architecture in the application. It is imperative for businesses to monitor these vulnerabilities and mitigate them in a timely manner. These vulnerabilities can be addressed in several ways such as modifying third-party dependencies, conducting regular secure code reviews, educating your software development team, and hiring experienced professionals. User activity monitoring may be one of the most obvious types of monitoring strategies for DevOps. Unusual requests or unexpected inputs such as multiple failed login attempts, unusual login times, and unknown login device should be constantly monitored to ensure that only authorized users can access the system. What’s more? Monitoring the behavior of users can also help detect unusual activities such as access privilege escalation. For instance, a developer attempting to access an admin account. Such unusual behavior and requests may trigger suspicion and make you more aware of potential insider threats or other cyberattacks that may occur due to poor user activity monitoring. Monitoring application log output is often underestimated, but if your services are distributed and you don’t have centralized logging in place, then this task is much more difficult. Further, if errors and vulnerabilities are not detected in real-time, they don’t hold that much value. It is important to ensure that faulty codes or error-prone codes generate notifications in real-time, and those notifications are easily searchable. The ability to trace a bug or error in a production environment is a huge bonus. Monitor your server’s health by analyzing the performance and uptime with respect to the available resources. Make sure that it is properly configured and scanning features are working as intended such as for identifying vulnerabilities in the application. Also, ensure servers are hardened to approved configurations. Monitoring tools for DevOps should be able to collect the performance time-series data from open source agents, track the application of machine learning for alerting and reporting, and collect data in scalable time-series databases. Here’s a set of functionalities that one or more of your monitoring tools might provide: A DevOps monitoring tool you choose should be capable of monitoring your full stack end-to-end and providing faster troubleshooting and quick remediation. This list is not essentially comprehensive but rather intended to cover the largest feature sets in an application: Infrastructure monitoring is a key component of full-stack application monitoring strategies. What should tools measure? Further, they should also be able to provide a history of trends, time-series data of the measurements, and aggregation of data with process-level drill down. Network monitoring tools should have the capability to measure performance metrics like latency, different port level metrics, bandwidth, the CPU usage of hosts, network packets flow, and offer custom metrics as well. Generally, network monitoring tools need a platform that works across various network topologies such as cloud-based networks and heterogeneous networks. Application performance monitoring is where logs are searched, collected, and centralized with tracing and profiling available on the application. It also helps provide measurements on performance such as availability, error rate, throughput, user response time, slow pages, page loads, third-party JavaScript slowness, track SLAs, browser speed, and checks for end-user transactions. While this list is not exhaustive by any means, it should give you an idea of what your existing monitoring tools offer and what are the loopholes in your DevOps monitoring strategy. Create an outline framework that can be used as a starting point for the evaluation process by DevOps teams. By outlining goals that apply to your overall DevOps monitoring strategy, you can narrow down your focus during evaluation to specific questions such as: “Does this monitoring tool meet my goals and needs?” Understanding DevOps monitoring tools and the functionalities they offer will allow you to dive deep into feature functionality during the evaluation process. What’s more? Knowing the monitoring functionality related to each monitoring aspect such as application monitoring or infrastructure will help inform the best choice for a more specific and comprehensive DevOps monitoring strategy. Here are some of the best DevOps monitoring tools on the market today: It is crucial for businesses to create and implement effective DevOps monitoring strategies. Quicker development processes in DevOps pose several challenges, specifically regarding vulnerabilities and loopholes in the system that might be left due to rapid processes or lack of testing. Having efficient and scalable DevOps monitoring strategies will help you gain insights into your application, identify loopholes early in the process, and mitigate them. Remember that while one area of monitoring may be more important for your business than another, it is essential to evaluate various aspects of your application or project.
