AIOps Observability: Going Beyond Traditional APM

AIOps is an emerging technology that applies machine learning and analytics techniques to IT operations. AIOps enables IT teams to leverage advanced algorithms to identify performance issues, predict outages, and optimize system performance. Nodesource sees significant advantages for developers and teams to increase software quality by leveraging AIOPS. We have extended our platform’s (N|Solid) observability capabilities to include AIOps, enabling developers to leverage advanced machine learning and analytics techniques to optimize their Node.js applications.

Our N|Solid platform provides the most advanced visibility into Node.js applications, enabling developers to quickly identify performance issues, detect security vulnerabilities, and troubleshoot errors. N|Solid achieves this level of observability through real-time performance monitoring, comprehensive metrics, and detailed instrumentation of Node.js applications.

Last year, we integrated OpenTelemetry into our runtime and were nearing the release of an extension of this layer into our console. This advancement will further extend our platform to support AIOps. Santiago Gimeno, a Senior Architect, sums up our vision of the integration with OTel (Open Telemetry) and N|Solid:

“In today’s world, where applications are becoming more complex and distributed, having a good observability solution is more important than ever. The emergence of OpenTelemetry as the de-facto standard for observability is key. It allows application developers to select solutions that adapt better to their needs. Even more, it allows for healthy competition between observability solution vendors. We support this approach and continue to take steps to ensure N|Solid stays compliant with the OpenTelemetry specification, so everyone can use what we believe is the best observability solution for Node.js.”

Key differences between an APM and Observability

APM (Application Performance Management) and observability are both methods of monitoring and managing the performance and health of software applications, but there are key differences between the two:

Scope: APM is focused on monitoring the performance of applications, while observability is a more comprehensive approach that includes monitoring the infrastructure and application stack, as well as the performance of individual services.

Metrics: APM typically relies on predefined metrics and thresholds to identify performance issues, while observability takes a more flexible approach to collect a wide range of data, including logs, metrics, and traces.

Root cause analysis: APM is designed to quickly identify the root cause of performance issues, often through alerting and automated remediation, while observability takes a more holistic approach that emphasizes the need to understand the relationships between different parts of the system to identify and fix issues.

Proactivity: APM is often reactive, focusing on identifying and fixing issues as they arise, while observability is more proactive, focusing on continuous monitoring and analysis to identify potential issues before they become critical.

Tooling: APM is often built around specific tools and technologies designed to monitor and analyze application performance, while observability is more flexible and adaptable, focusing on integrating a wide range of tools and technologies to provide a comprehensive system view.

You need to have both; they are important to monitoring and managing the performance and health of software applications.

This is why N|Solid is not only an APM but also has observability within its functionalities. And now, with the implementation of ML and SBOM, it goes beyond APM and supports the growing discipline of AIOps.

AIOps: Fundamental concept in Modern IT Operations

AIOps (Artificial Intelligence for IT operations) is an approach to IT operations that leverages machine learning and artificial intelligence to automate and optimize IT tasks. AIOps aims to enhance the efficiency and effectiveness of IT operations by leveraging the vast amount of data generated by various IT systems and applications.

Observability refers to IT teams’ ability to observe and understand the behavior of complex systems in real-time, using a combination of monitoring, logging, and analytics tools.

AIOps and observability enable IT teams to proactively monitor and manage IT systems, applications, and infrastructure, allowing them to identify and resolve issues quickly. AIops uses machine learning and AI algorithms to identify patterns in large amounts of data, while observability provides the visibility and context needed to understand the behavior of complex systems.

Modern Observability in Place

Support for open-source tracing tools and standards like OpenTelemetry facilitates team collaboration in resolving issues. Open Telemetry is the second most active CNCF project, behind only Kubernetes, showcasing its importance to the industry.

Following this standard, N|Solid (since N|Solid 4.8.0) supports OTEL:
– Implements the OpenTelemetry TraceAPI, allowing users to use the de-facto standard API to instrument their code.
– It supports using many instrumentation modules available in the Open Telemetry ecosystem. It supports exporting traces using the Open Telemetry Protocol(OTLP) over HTTP.
– With this feature is now possible to send N|Solid runtime monitoring information (metrics and traces) to backends supporting the Open Telemetry standard like multiple APMS (Dynatrace, Datadog, Newrelic, etc.).

Additionally, we included OTEL in the ‘APM performance dashboard,’ an open-source tool we released to the community, enabling developers and organizations to understand the impact of APM tools’ performance.

_Img APM’s Performance Dashboard View

Recent enhancements to the tool include the following:

Updated the data with N|Solid 4.8.0 -> 16.16.0 and 14.20.0
Added a few new tests: especially with different solutions for graphql.
Added more APMs: opentelemetry, AppDynamics

Added testing of N|Solid against Datadog, Dynatrace, and NewRelic.

Do you want to implement OTel in your Node.js application? ????

Enriching telemetry data with metadata is an important aspect of observability, and OpenTelemetry provides a flexible and extensible framework for doing so. However, there can be challenges in implementing this in practice, especially when dealing with multiple tools and technologies.

One approach to addressing this challenge is to use a centralized configuration management tool to ensure consistency in metadata enrichment across your observability stack. Please review the following articles to give you an accurate guide to implementing Opentelemetry in your project.

SBOM: The Essential Building Block for Cybersecurity

Software Bill of Materials (SBOMs) is how companies provide a comprehensive inventory of all the components, libraries, and dependencies used in a software system. This information helps organizations identify potential vulnerabilities and manage the risk of software supply chain attacks.

SBOM is a detailed list of all the components, libraries, and dependencies that make up a software system. It includes information such as the names and versions of the components, their sources, and any associated risks or vulnerabilities.

Just as a supply chain document in manufacturing and product development outlines the origin and journey of raw materials and components, a software bill of materials (SBOM) does the same for software components.

SBOM Adoption via Executive Order from the EEUU

On May 12, 2021, President Joe Biden released the Executive Order (EO) on Improving the Nation’s Cybersecurity with a specific requirement for SBOMs. Read here the executive order.

SBOM includes information on their origin, version, and security risk. Just as manufacturers rely on supply chain documentation to ensure the quality and safety of their products, organizations can use SBOMs to manage software supply chain risks and ensure the security and compliance of their software systems. In both cases, having accurate and up-to-date information is critical to making informed decisions and avoiding potential harm.

Since December 2022, in its v4.9.0, N|Solid has SBOM support (Software Bill of Materials).

N|Solid has added support for SBOM reporting in all applications connected to the N|Solid console; the report is offered in two formats: JSON and PDF; it contains the information for the dependency inventory of a specific application; it includes valuable information like licensing and the security status for each dependency used.

Start using SBOM in all applications connected to the N|Solid console START NOW

The role of SBOM:

The Linux Foundation released the results of a survey: The State of Software Bill of Materials (SBOM) and Cybersecurity Readiness, carried out within the framework of the US presidential order on SBOM, where 412 organizations worldwide participated in a survey. Here is the infographic with the highlights.

With the ever-increasing use of third-party components in software development, having an accurate and up-to-date SBOM is essential for ensuring the security and integrity of a company’s software systems; an organization can use SBOMs for many purposes. Some of them are:

Allow organizations visibility and control over their software supply chain, enabling them to make informed decisions about software security, compliance, and licensing.

Companies can proactively manage software risk, improve their cybersecurity posture, and protect their customers and critical data.

Comply with industry standards and regulations. This refers to the process of ensuring that an organization is using software in accordance with its license agreements. This includes ensuring that the software is being used within the terms of the license agreement and that the organization uses only the licenses it has purchased.

Compliance and customer Audit. Ensure that it meets the specified quality criteria. This may include testing, inspections, and reviews to identify any issues or defects and make sure that the product or service meets the customer’s requirements and the high standards of quality that the industry expects.

Despite the clear benefits of SBOMs, the use of SBOMs has traditionally been limited to more than just the largest and most advanced organizations. However, the increasing threat of software supply chain attacks and the growing recognition of the importance of SBOMs are expected to drive the widespread adoption of SBOMs in the near future.

The United States Executive Order on the Nation’s Cybersecurity outlines new requirements for SBOMs and other security measures for software used by federal agencies. This order highlights the importance of SBOMs in ensuring the security of software systems and demonstrates the growing recognition of their value in the industry.

Implementing SBOM in Your Organization

Companies are increasingly aware of their risks by needing to be clearer about their technologies, especially in the open-source ecosystem. according to the Linux Foundation survey, what are the key activities for securing the software supply chain? These answers serve as a basis for understanding the importance of this concept in the ecosystem.

Understanding the process of implementing an SBOM in your organization, from assessing your current software landscape to integrating the SBOM with your existing security and compliance tools, will help you to effectively manage software supply chain risks and ensure the security and compliance of your software systems.

Assessment: The first step is to assess the organization’s current software landscape and identify which software systems and components need to be included in the SBOM.

Inventory: Once the software systems and components have been identified, the next step is to create an inventory of all the components and their attributes, such as name, version, source, and any associated risks or vulnerabilities.

Automation: To ensure the SBOM is accurate and up-to-date, consider automating the SBOM creation process through tools or scripts that can extract information from source code and dependencies.

Integration: The SBOM should be integrated with the organization’s existing security and compliance tools, such as security assessment and license compliance tools, to ensure that the information contained in the SBOM can be effectively utilized.

Monitoring: Regular monitoring of the SBOM should be implemented to ensure that it remains up-to-date and that any changes or updates to software components are accurately reflected in the SBOM.

Review: The SBOM should be regularly reviewed to identify potential security risks or vulnerabilities and ensure compliance with industry standards and regulations.

Training: Finally, provide training to all relevant personnel, including developers and security teams, to ensure that the SBOM is being used effectively and that everyone understands the importance of keeping the SBOM up-to-date.

By following this path, organizations can effectively implement an SBOM and use it to manage software supply chain risks, improve their overall cybersecurity posture, and ensure compliance with industry standards and regulations.

By using NodeSource Certified Modules, organizations can be confident that they are using high-quality, secure, and reliable components in their Node.js applications. In addition, NodeSource provides ongoing maintenance and support for these modules, ensuring that they continue to work effectively and securely over time. By using NodeSource Certified Modules, organizations can simplify the process of selecting and using npm packages in their Node.js applications, helping to ensure that their applications are secure, reliable, and performing optimally for their users.

_NCM enables you to quickly and easily generate SBOMs that:
_

Identify all open-source libraries.
Track and document each component, including direct and transitive dependencies.
Update automatically when components change.
Identify vulnerabilities.
Provide a path to remediation that ensures updates are backward compatible and won’t break the build.

Illustrative Example of Software Life Cycle and Bill of Materials Assembly Line

According to the SBOM document, to stay compliant, the data fields that must be in an SBOM are:

Component name
Component version
Unique identifier for the software
Relationship with other dependencies
Developer name
Name of tool used to create the SBOM document
Document creation date and time

N|Solid complies with the National Institute of Standards and Technology (NIST) laying out the guidelines for an SBOM document.

Conclusion:

SBOMs are an important tool in the fight against software supply chain attacks. Organizations can better track and manage their software components and identify potential risks by incorporating them into the software development process. In addition, SBOMs provide valuable insights into the supply chain history of a product, helping to ensure that all components are sourced from reputable and trustworthy sources.

As a company, ensuring the security of the code and systems you use and create is important. That’s why it is truly important:

To ensure the security of open-source components in your supply chain, it is crucial to track their licenses, vulnerabilities, and associated risks.
To avoid coding security defects and weaknesses, it is important to know common attack methods such as buffer overflows, SQL injection, and cross-site scripting. Vulnerabilities can be difficult to identify, as someone often plants malicious code with in-depth knowledge of the system.
To secure your development and delivery infrastructure, it is recommended to conduct a binary analysis of the container images to inspect component signatures and identify any open-source components and sensitive data present.
To ensure the security of APIs and protocols used for communication with other systems, a lack of visibility and control can put critical systems and sensitive information at risk.

However, implementing SBOMs effectively can be a complex and time-consuming process, and organizations need to choose the right tools and processes to ensure the accuracy and relevance of their SBOMs. We are sure that N|Solid can help! 💪

AI – growing in value in the software development lifecycle

Img #1 AI vs ML concepts

Put in context, artificial intelligence refers to the general ability of computers to emulate human thought and perform tasks in real-world environments, while machine learning refers to the technologies and algorithms that enable systems to identify patterns, make decisions, and improve themselves through experience. — https://ai.engineering.columbia.edu

The technology world has been abuzz with the growing hype of artificial intelligence (AI). This is understandable as AI promises to revolutionize business and everyday life; from self-driving cars to automated customer service, AI will shape the future of our civilization. As technology continues to advance, the potential applications for AI are seemingly endless.

AI and ML (Machine Learning) are closely related, but not identical. AI is the broader concept of machines being able to perform tasks that would normally require human intelligence, such as visual perception, speech recognition, decision-making, and language understanding. ML is a specific subset of AI that is focused on the development of algorithms and statistical models that allow computers to “learn” from data, without being explicitly programmed. In other words, ML is a method for achieving AI.

ML and AI can help developers build better software in several ways. Some examples include:

Automating repetitive tasks: ML algorithms can be used to automate repetitive tasks that would otherwise require human intervention. For example, a ML model could be trained to automatically classify and categorize emails, reducing the need for manual sorting.

Improving software performance: ML algorithms can be used to optimize the performance of software systems. For example, a ML model could be trained to predict the load on a server, allowing the software to dynamically adjust its resource usage in response.

Enhancing the user experience: AI-powered software can provide a more personalized and intuitive experience for users. For example, a chatbot powered by natural language processing (NLP) could be used to provide customer service, or a recommendation system powered by ML could be used to suggest products to customers.

Predictive Maintenance: AI and ML algorithms can be used to predict when a machine or equipment is likely to fail, allowing maintenance to be performed before the failure occurs.

Identify and Fix Bugs: AI and ML can be used to automatically identify and fix software bugs, reducing the need for human intervention.

Improve Cybersecurity: AI and ML can be used to identify and mitigate cyber threats and detect suspicious activity on a network, which help to improve cybersecurity.

We believe there is great promise for developers to leverage new tooling that helps them focus on the solution and resolve issues as fast as possible, reducing security risks and deliver amazing user experiences. We see AI and ML as a major step forward to build better software.

Node.js expose the potential of AI.

Img 2 – AI Frameworks

We believe Node.js is a powerful technology for leveraging the potential of AI. It allows developers to easily create and manage AI applications, as it features extensive APIs for interacting with AI-related services. With Node.js, developers can create AI-backed applications that can be deployed across various platforms, making it an invaluable asset for businesses looking to leverage the power of AI.

The combination of Node.js and AI will also make it possible to create sophisticated applications that can interpret data in real-time, allowing businesses to improve their customer experience dramatically. As AI advances, Node.js will be a key tool in helping developers make the most out of the technology.

Recently there are several AI projects that are ushering a massive wave of exploration. OpenAI and its ChatGPT has become one of the fastest tools ever adopted. We are impressed with the incredible progress of the OpenAI project and many others,we continue to study, experiment, and review implementations of these technologies and their potential for the ecosystem.

Links to other cool resources

GitHub OpenAI: https://github.com/openai/openai-quickstart-node

OpenAI Docs: https://beta.openai.com/docs/quickstart

Already, Node.js is being used by many companies to power their AI-driven applications, and this trend will only continue as more companies seek to take advantage of the power of AI. Node.js also allows developers to quickly set up and deploy AI-driven applications, further accelerating the development process. With Node.js and AI, businesses can create smarter, faster, and more efficient applications.

Nodesource Introduces Machine learning in N|Solid platform

N|Solid is a Node.js platform with an integrated AI development environment.

This feature allows for training models that will later detect similar patterns in your application data and fire custom events.

It also offers advanced analytics capabilities and support for various AI technologies, making it a powerful tool for businesses looking to capitalize on the potential of AI.

Img 3 – ML Feature Cover

N|Solid is part of a larger trend toward making AI and ML more accessible to developers, helping to utilize these advancements to deliver software solutions.. By providing an integrated platform for Node.js in production, N|Solid is making it easier for businesses to create sophisticated AI-driven models and reap the benefits that come with them.

Developers can start using this new feature in N|Solid immediately to:

Identify performance issues and present insights to resolve quickly
Apply insights across multiple applications
Smart analysis and detection of common Node.js performance issues with the bundled models we provide
Training of custom models to detect specific problems
Global notifications and events tracking for processes and applications

Below you will see ML in action inside N|Solid.

Machine Learning UI

In the N|Solid Console, the Machine Learning feature can be accessed from the app summary or process detail views.

Each handles different data sets and will have a different effect on the model you train.

Training ML Models

The Machine Learning models can be trained using two kinds of data sets. The models trained in the app summary view will use the aggregated data of all the processes running inside the app.

On the other hand, the models trained in the process detail view will use process-specific data.

Train a model in the app summary view.

When a process/app is first connected, it will take a certain amount of data to be successfully trained; you will find a progress loader under process configuration:

To train a model in an app summary page, click on Train ML Model button.

Train a model in a process detail view.

To train a model in a process detail page, click on Train ML Model button.

Modal creation and training

After clicking on the Train ML Model button, a modal will open; here, you can create, filter, and train models; this modal is the same for both pages.

To create a model, click on CREATE NEW MODEL.

Name and briefly describe the model, then save.

Select the created modal and click on ‘TRAIN.’

When the trained model finds a data pattern similar to the one it was trained with, it will fire an event and show a banner on top of the navbar.

Click on View Event to be redirected to the events tab; here, you will find the most recent machine learning event.

The events will also appear in the application status section; clicking on VIEW ANOMALIES will redirect to the events tab.

Manage the default and custom models.

Machine Learning models can be administered in the settings tab, where you will find a set of default models and the user-trained models; here, the frequency of events being fired can be modified, and the custom user models can be deactivated, deleted, or edited.

For a full reset of the created models, click on RESET MODELS.

Custom user models have edit and delete icons; these models are found beneath the default models.

PLEASE NOTE Only the name and description of the user-created model can be edited; if you want to change the model data, please retrain the model in-app summary or in the process detail pages. Default models are activated by default; these can only be activated or deactivated.

Our Machine learning feature has been live since November 2022; if you want to review the official documentation, you can do it here.

Interview With Italo José Core committer at @herbsjs

@ItaloJosé is Microsoft MVP in the Node.js category and works at NodeSource as a Software Engineer; He organizes CityJS Brazil.

We are thrilled to be part of developing powerful tools like N|Solid. We are immensely proud of our engineers who have dedicated their time and expertise to support the open-source ecosystem. This is our way of giving voice and visibility to the projects they are passionate about.

We want to recognize Italo José’s work with Herb.js on this occasion. He has been working on the Herbs.js project since 2020, where he developed the initial versions of the CLI, made significant contributions to numerous repositories, and mentored new contributors.

NS: What benefits does Herbs.js provide?

IJ: Different from other frameworks that help you to write a better infrastructure layer, like the API, database layer, documentation, and tests. The Herbs.js want to help you avoid writing it and focus on what matters, the domain’s code. How do we do it? We read your use case and provide you with the infrastructure; this way, you can save more than 50% of the time developing a server-side application.

It’s good for the business and developers that will stop writing boring and repetitive code for every project.

NS: How can I use Herbs.js to improve my development process?

IJ: The first step is writing your entities and use cases using the @herbsjs/herbs library, besides you have a more organized and readable use cases’ code. After that, you can add our glues(other libraries) that will read your use case and provide you the infrastructure code like rest or GraphQL APIs, documentation, repositories layer and more.

NS: What are the most popular features of Herbs.js?

IJ: Our CLI, the herbs2rest libraries.
The CLI, you know, helps you to generate and maintain a project using the Herbs.js. The herbs shelf reads your use cases and provides human documentation (this is my favorite).

The herbs2rest plugin reads your use case and provides a configured express instance containing all endpoints, an error handling layer, and auth layer for you.

These are the three most popular, but we have plugins for GraphQL, databases, tests, and more.

NS: How does Herbs.js simplify the development process?

IJ: Besidesprevents you writing 80% of the infrastructure code; we provide you with and structured way to write the use cases that allow you to maintain your code self-documented and organized in steps; it’s interesting because this way, new developers and non-developers can understand in a fast way what is happening in your code, it allows for example, project owners validate your use case rule for going to production.

Besides, we save time by avoiding writing the “repetitive” infrastructure code in all projects in our lives.
