Perf provides performance monitoring capabilities. eBPF enables custom tracing programs to be run efficiently in the kernel via just-in-time compilation. Tracing tools like perf, systemtap, and LTTng provide user interfaces.
How To Build Amazing Products Through Customer FeedbackProduct School
User research is important to understand customers and their needs. Some key questions for user research include:
- How do users currently solve the problem we want to address and what do they like/dislike about current solutions? Understanding user behaviors and pain points is important.
- What are users' goals, frustrations, stresses and what excites them? Getting a holistic view of users' experiences provides valuable insights.
- How do competitors' customers perceive and use competitive products? Learning what other companies' customers value helps understand the market.
APM is a tool that monitors application performance and user experience by tracking metrics like load and KPIs. It allows seeing how applications are used by real users and identifying problems that impact sales or brand experience. Observability aggregates data from logs, metrics, and traces to assess overall system health, while APM directly focuses on gauging user experience. Both ensure good user experience but in different ways - APM actively collects data related to response time, while observability passively examines various data sources. Monitoring tracks predefined metrics over time to understand system status, but observability analyzes related data to determine the root cause of issues.
This document provides an overview and agenda for a meetup on distributed tracing using Jaeger. It begins with introducing the speaker and their background. The agenda then covers an introduction to distributed tracing, open tracing, and Jaeger. It details a hello world example, Jaeger terminology, and building a full distributed application with Jaeger. It concludes with wrapping up the demo, reviewing Jaeger architecture, and discussing open tracing's ability to propagate context across services.
Distributed tracing allows requests to be tracked across multiple services in a distributed system. The Jaeger distributed tracing system was used with the HOTROD sample application to visualize and analyze the request flow. Key aspects like latency bottlenecks and non-parallel processing were identified. Traditional logs lack the request context provided by distributed tracing.
Tracing Micro Services with OpenTracingHemant Kumar
Tracing in the world of micro services has become a standard with people using distributed tracers like Zipkin, Jaeger, Appdash etc. But, with so many different tracers, its confusing to choose one tracer and then painful to replace a tracer. That's where OpenTracing comes in. OT provides a consistent, vendor-neutral API to allow users to choose whatever distributed tracer they need and can change the tracer with just an O(1) operation.

Completing a transition to a microservices-based architecture makes every software engineer feel good. You can be proud of requests spanning multiple individual services, each with isolated single responsibility. Exactly as you dreamed it would be.
In the course of this transition however, you will have also created several new problems. Among these is a whole new level of complexity related to understanding the behavior of the application when troubleshooting a problem. If you have ever wrestled with pinpointing the exact root cause during a post-mortem, this talk is for you.
We will show you how capturing the runtime transparency of the distributed and dynamic architecture is possible. Better yet, we will cover both simple and advanced examples about how taking this route gives you an objective and evidence-based ability to zoom in to the problem.
After attending the talk you will understand how distributed tracing will help your team during incident response and post-mortems.

Context-aware Fast Food Recommendation with Ray on Apache Spark at Burger KingDatabricks
For fast food recommendation use cases, user behavior sequences and context features (such as time, weather, and location) are both important factors to be taken into consideration. At Burger King, we have developed a new state-of-the-art recommendation model called Transformer Cross Transformer (TxT). It applies Transformer encoders to capture both user behavior sequences and complicated context features and combines both transformers through the latent cross for joint context-aware fast food recommendations. Online A/B testings show not only the superiority of TxT comparing to existing methods results but also TxT can be successfully applied to other fast food recommendation use cases outside of Burger King.

OSMC 2022 | Unifying Observability Weaving Prometheus, Jaeger, and Open Sourc...NETWAYS
Observability is a hugely popular topic, however, for open-source users, significant challenges remain. For starters, related licensing is frequently problematic—and even when it works, there is no pure Apache 2.0 licensed technology to get data collection and visibility into your logs, metrics, and traces. Thankfully, this is gradually changing as the community builds new capabilities into OpenSearch Dashboards to unify the visualization of logs from OpenSearch, metrics from PromQL compatible systems, and traces from Jaeger. In this session, we’ll examine how this important project is evolving as a fork of the previously popular ELK stack. We’ll also take a closer look at the current state of OpenSearch and Jaeger and discuss how these efforts are going to provide a foundation for unified observability to the open-source communities. By using OpenTelemetry for data collection, this foundation provides a pure Apache 2.0 licensed open-source platform for unified observability. OpenSearch also includes features like Alerting and Machine Learning, which are not part of Jaeger today. The work on this foundational integration is well underway and will provide open-source users with a solid alternative to vendor controlled and provided solutions. This also opens up the marketplace for solutions to be created to host and manage these at scale, something we’ve seen with countless other CNCF projects. This talk will be presented by a contributor and maintainer of OpenSearch, Jaeger, and OpenTelemetry, which are all vibrant user communities. Join the conversation!

Creating and deploying microservices is easy. The real problem is how to manage and support these services out in the wild and in production. What happens when these services stop working or worse yet when they are running but running slowly? Which service instance is the culprit? This session talks about how you can leverage metrics and tracing tools in order to give better visibility into the distributed nature of a microservice architecture in a Kubernetes environment.
This presentation will discuss key concepts of metrics and tracing and highlight Open Source Projects available that address: 1) the value of instrumentation and how Prometheus can be used to monitor and measure a Kubernetes cluster, and 2) how Jaeger can provide visibility into your applications and microservices.
Will provide a demo of Microservices leveraging Prometheus and Jaeger deployed to Kubernetes cluster.

It then covers requirements for building microservices like security, asynchronous communication, monitoring, logging, tracing, service discovery, configuration management, and circuit breakers. Specific open source tools are mentioned for each requirement area, including RabbitMQ, Kafka, Prometheus, Zipkin, Elasticsearch, Eureka, Spring Cloud Config, and Kubernetes. The document concludes by asking if the audience has any additional questions.
This document summarizes microservices on Kubernetes and the benefits of using Istio as a service mesh. It discusses some of the issues with earlier microservices architectures and how Istio addresses them. The key points are:
- Istio is an open platform that provides a service mesh for microservices on Kubernetes to enable security, observability, and traffic management between services.
- It addresses issues with earlier architectures that used an API gateway for routing by deploying Envoy proxies as sidecars, which provide features like discovery, load balancing and failure handling.
- The Istio control plane manages the proxies using components like Pilot and Mixer to configure routing and enforce policies.
Istio is an open platform for providing a service mesh on Kubernetes clusters. It consists of three main components: Envoy proxies that mediate service-to-service communication, Pilot that configures the proxies, and Mixer that enforces policies and collects telemetry data. Istio injects Envoy sidecar proxies into applications so they can provide features like load balancing, authentication, failure recovery, and observability without requiring code changes. This provides a way to manage microservices that is more robust and flexible than using an API gateway alone.
This document discusses using Prometheus for application monitoring on Kubernetes. It describes the current monitoring systems in use and their limitations. Prometheus is introduced as an open-source monitoring system developed by SoundCloud. Two approaches are presented for using Prometheus on Kubernetes - running Prometheus on EC2 instances and pointing it at Kubernetes, or using the Prometheus Operator which automates Prometheus configuration based on Kubernetes resources. The Prometheus Operator approach is recommended for its simplified configuration.

ADVXAI IN MALWARE ANALYSIS FRAMEWORK: BALANCING EXPLAINABILITY WITH SECURITYijscai
With the increased use of Artificial Intelligence (AI) in malware analysis there is also an increased need to
understand the decisions models make when identifying malicious artifacts. Explainable AI (XAI) becomes
the answer to interpreting the decision-making process that AI malware analysis models use to determine
malicious benign samples to gain trust that in a production environment, the system is able to catch
malware. With any cyber innovation brings a new set of challenges and literature soon came out about XAI
as a new attack vector. Adversarial XAI (AdvXAI) is a relatively new concept but with AI applications in
many sectors, it is crucial to quickly respond to the attack surface that it creates. This paper seeks to
conceptualize a theoretical framework focused on addressing AdvXAI in malware analysis in an effort to
balance explainability with security. Following this framework, designing a machine with an AI malware
detection and analysis model will ensure that it can effectively analyze malware, explain how it came to its
decision, and be built securely to avoid adversarial attacks and manipulations. The framework focuses on
choosing malware datasets to train the model, choosing the AI model, choosing an XAI technique,
implementing AdvXAI defensive measures, and continually evaluating the model. This framework will
significantly contribute to automated malware detection and XAI efforts allowing for secure systems that
are resilient to adversarial attacks.

Analysis of reinforced concrete deep beam is based on simplified approximate method due to the complexity of the exact analysis. The complexity is due to a number of parameters affecting its response. To evaluate some of this parameters, finite element study of the structural behavior of the reinforced self-compacting concrete deep beam was carried out using Abaqus finite element modeling tool. The model was validated against experimental data from the literature. The parametric effects of varied concrete compressive strength, vertical web reinforcement ratio and horizontal web reinforcement ratio on the beam were tested on eight (8) different specimens under four points loads. The results of the validation work showed good agreement with the experimental studies. The parametric study revealed that the concrete compressive strength most significantly influenced the specimens’ response with the average of 41.1% and 49 % increment in the diagonal cracking and ultimate load respectively due to doubling of concrete compressive strength. Although the increase in horizontal web reinforcement ratio from 0.31 % to 0.63 % lead to average of 6.24 % increment on the diagonal cracking load, it does not influence the ultimate strength and the load-deflection response of the beams. Similar variation in vertical web reinforcement ratio leads to an average of 2.4 % and 15 % increment in cracking and ultimate load respectively with no appreciable effect on the load-deflection response.

Passenger car unit (PCU) of a vehicle type depends on vehicular characteristics, stream characteristics, roadway characteristics, environmental factors, climate conditions and control conditions. Keeping in view various factors affecting PCU, a model was developed taking a volume to capacity ratio and percentage share of particular vehicle type as independent parameters. A microscopic traffic simulation model VISSIM has been used in present study for generating traffic flow data which some time very difficult to obtain from field survey. A comparison study was carried out with the purpose of verifying when the adaptive neuro-fuzzy inference system (ANFIS), artificial neural network (ANN) and multiple linear regression (MLR) models are appropriate for prediction of PCUs of different vehicle types. From the results observed that ANFIS model estimates were closer to the corresponding simulated PCU values compared to MLR and ANN models. It is concluded that the ANFIS model showed greater potential in predicting PCUs from v/c ratio and proportional share for all type of vehicles whereas MLR and ANN models did not perform well.
