If something has observability it means it can be seen.

An application is said to be observable if its current state can be measured based on the data it generates, such as metrics longs and traces.
OT2, or OpenTelemetry, is an observability framework for cloud-native software that provides a set of APIs, libraries, agents, and instrumentation to capture distributed traces and metrics from applications. It helps developers monitor and understand the performance of their applications across various environments. OT2 aims to standardize observability practices and facilitate easier integration with various back-end systems for data analysis.
poles are the plot of the transfer function of a system on the left side of the origin, in s-plane. zeroes are the right side plot. poles and zeroes specifies the absolute stability of the system.. they also gives the observability and controllability of the system..
The speed of a stealth fighter, such as the F-22 Raptor or F-35 Lightning II, can reach over Mach 2, which is approximately 1,500 miles per hour (2,414 kilometers per hour) at altitude. However, exact speeds can vary based on specific models and mission configurations. Stealth fighters are designed not only for speed but also for advanced maneuverability and low observability.
Instrumentation tools are software applications and frameworks used to monitor, analyze, and optimize the performance of systems and applications. They gather metrics, logs, and traces to provide insights into system behavior, helping developers and operators troubleshoot issues, enhance performance, and ensure reliability. Common examples include Prometheus for monitoring, Grafana for visualization, and New Relic for application performance management. These tools are essential in modern DevOps and observability practices.
The B-2 Spirit stealth bomber is primarily constructed using advanced composite materials, which include carbon-fiber-reinforced plastics and epoxy resins. These materials are designed to minimize radar cross-section and enhance stealth capabilities. Additionally, the aircraft incorporates aluminum and titanium alloys in certain structural components for strength and durability. The use of radar-absorbent materials (RAM) further contributes to its low observability.
The F-22 Raptor, one of the most advanced stealth fighters, has a top speed of approximately Mach 2.25, which is about 1,500 miles per hour (2,414 kilometers per hour) at altitude. Additionally, it can sustain supersonic speeds without afterburners, a capability known as supercruise. Other stealth fighters, like the F-35, have slightly lower top speeds, around Mach 1.6. Overall, stealth fighters are designed for high-speed performance while maintaining low observability.
The speed of stealth planes varies depending on the specific model and design. For instance, the Northrop Grumman B-2 Spirit has a maximum speed of around 630 mph (1,014 km/h), while the Lockheed Martin F-22 Raptor can reach speeds of approximately 1,500 mph (2,414 km/h) when in supercruise mode. Stealth capabilities often prioritize low observability over sheer speed, but some models can still achieve impressive velocities.
