The company J, where developer Y works, is using an outdated installed version of Jira. It is installed somewhere in the IDC, and we know that the machine is old, but due to the licensing policy being assigned on a hardware basis, it is difficult to upgrade or move the installation. Y was able to check the transactions located at the upper part of the Y-axis using the X-View chart, a feature of the installed APM. *You can view the detailed content of the blog through the related link.

The dynamic method profiling feature of JENNIFER allows you to change the profiling level of transactions without restarting the AP server. By the way, what is a profile? In social networks, a profile represents an individual's identity or biography and contains information that outlines them. Similarly, a transaction profile includes information about individual methods' response times, parameters, or return values related to the transaction. Profile information includes the behavior of transactions used by the code's class to complete the transaction, the methods executed and their execution times, and the execution times of SQL queries run during database access. All of this information is very effective in understanding the behavior of transactions and analyzing the root causes of issues. *For more details, you can view the related links on the blog.

We would like to introduce a day in the life of Developer Y, who is working to solve performance issues that cannot be improved through individual transaction analysis. As usual, Y was in charge of the APM log collection server. Then, he received a report that the following content was output in the collection server's logs, and data was not being displayed on the dashboard. Upon checking the details, it was found that each request was processed within one second, but individual processing took between 294ms and 401ms. *For more detailed information, you can view the related links.

This time, we will take a look at Helm, which allows for easy installation of applications in a Kubernetes environment. Helm is an open-source application package management tool for Kubernetes environments that enables easy installation, distribution, upgrading, and rollback of applications. Helm defines applications in a package called a Chart, which allows applications to be configured and distributed as a unit along with templated resources. Additionally, similar to package management tools like yum or apt in Linux environments, it manages various elements necessary for running applications in a packaged form. It is a powerful tool that simplifies the installation and management of software packages by allowing for bulk installation. The author manages all applications in the Kubernetes environment using Helm. *For more details, you can view the blog through the related links.

This time, we will take a look at the open-source monitoring system Prometheus. Before getting into the main topic, let's examine how monitoring in a Kubernetes environment differs from monitoring in a traditional VM (virtual machine) environment. I believe it will be easier to understand if we can identify the differences from existing environments. *You can view the detailed content of the blog through the related links.

The author believes that the most important aspects of system operation are monitoring and alerts. By automatically and quickly grasping the state of the system through alerts, operational efficiency can be improved. The significance of an alert system lies in its ability to quickly confirm important information without complex processes and without missing anything. It is practically impossible for operators to check the state of the system one by one. While implementing an effective alert system may seem straightforward, it is actually a very challenging task. *For more details on the blog, you can view it through the related links.

JENNIFER has strengths in real-time monitoring and offers a variety of features for quick analysis. However, to conduct a comprehensive analysis, it takes time to check insights (the truth of the situation) and identify issues while navigating multiple screens and charts. Quick analysis is essential, especially in situations where problems arise, and it is very important to reduce the time spent checking multiple screens at that time. *You can view the detailed content of the blog through the related links.

Logs are necessary for handling system failures, resolving performance issues, and monitoring security. This time, we will check how to effectively manage application logs in a Kubernetes environment. First, let's look at the configuration of application logs. According to the 12-Factor App guide, it is recommended that logs in a container environment be output to standard output (stdout) and standard error (stderr), which is a fundamental principle of application logging in Kubernetes. *For more details, you can view the blog through the related links.

This time, we will introduce a variety of open-source tools that can be used for Kubernetes management. Kubernetes excels in diversity and scalability with its powerful container orchestration capabilities. However, its power also brings complexity. By utilizing the open-source tools introduced here, such complex tasks can become easier. *For more details about the blog, you can view it through the related links.

This time, we will check node auto-scaling. In a cloud environment, scaling up and down worker nodes (VM instances) is easier compared to on-premises environments. Just as we used AWS auto-scaling in a VM environment to flexibly utilize EC2 resources according to system load before using Kubernetes, we can freely scale up and down worker nodes in a Kubernetes environment as well. In a Kubernetes environment, node auto-scaling can be done using Cluster AutoScaler (CAS) and Karpenter. Karpenter is simpler in structure compared to the existing CAS, making it faster and more flexible. *For more details, you can view the related links.

Batch processing is being carried out in many systems, regardless of whether they are new or old. Although there are various types of batch processing, such as night batches and online batches, differing in purpose, scale, and complexity, one common point is that monitoring is rarely conducted. When it is done, it typically only involves alerts for the start, end, and abnormal termination of the batch. The perception that batch processing finishes on time and has fewer failures compared to online processing is one reason for the lack of monitoring. However, in the current context where service outages directly impact sales and customer trust, not only is the speed of recovery during failures important, but regular performance checks to prevent failures beforehand are also becoming crucial. Additionally, in the transition from on-premises environments to cloud environments, it becomes possible to ensure stable operations by conducting design, development, and testing using objective performance data. *For more details, you can view the related links.

JENNIFER provides error events for a variety of error causes. Anomaly detection is designed to detect performance degradation under sudden load. When metrics deviate from the upper or lower limits of the confidence interval, an alert is issued. The occurrence of anomaly detection events is periodically determined with consideration for performance. This period is the measurement time. *For more details, you can view the related links.

Karpenter actively changes the number of nodes to optimize the cost of nodes. When a new node is launched to generate a new Pod, it creates a new node that is the least expensive based on the request capacity set for the Pod, removes nodes among the existing ones that have low usage, and moves the Pods running on existing nodes to the new node. In this process, existing Pods are deleted and new Pods are started. To ensure that the restart of Pods does not affect customer service, the following options are necessary: TerminationGracePeriodSeconds, PodDisruptionBudget, PriorityClass This time, we will review these options. *For more details, you can view the related links.

This time, we will check how to perform more detailed scheduling of Pods. Main content: - For the stability of the service, we will separate the nodes that can run between Pods and review the Advanced Pod Scheduling feature, which allows the same application to run on different nodes of Pods. Practical tasks: - Set Taints, Tolerations, and Node Affinity to run Pods on specific nodes. - Set Pod Anti-Affinity to prevent Pods from running on the same node. *You can view the detailed content of the blog through the related links.
