- In this paper, we discuss a method for automatic monitoring of hardware and software events using performance monitoring counters. Computer applications are complex and utilize a broad spectra of the available hardware resources, where multiple performance counters can be of significant interest to understand. The number of performance counters that can be captured simultaneously is, however, small due to hardware limitations in most modern computers. We suggest a platform independent solution to automatically retrieve hardware events from an underlying architecture. Moreover, to mitigate the hardware limitations we propose a mechanism that pinpoints the most relevant performance counters for an application's performance. In our proposal, we utilize the Pearson's correlation coefficient to rank the most relevant performance counters and filter out those that are most relevant and ignore the rest.

- Fault management is a key function to guarantee the quality of the service. Research has done a lot to improve fault supervision, and investigation is ongoing in fault prediction, thanks to the potentials of artificial intelligence and machine learning. In this study, we propose a fault management framework that puts an emphasis on fault recovery: a framework developed on multi-layer function and a fault recovery methodology distributed over several technological layers. The basic principle of our proposal is that the system's complexity exposes it to a higher probability of temporary error. Newfound attention to the fault recovery phase is the key to keeping the service's quality high and saving maintenance costs by decreasing the return rate.

- Processing capacity distribution has become widespread in the fog computing era. End-user services have multiplied, from consumer products to Industry 5.0. In this scenario, the services must have a very high-reliability level. But in a system with such displacement of hardware, the reliability of the service necessarily passes through the hardware design. Devices shall have a high quality, but they shall also efficiently support fault management. Hardware design must take into account all fault management functions and participate in creating a fault management policy to ensure that the ultimate goal of fault management is fulfilled, namely to increase a system's reliability. Efficiently and sustainably, both in the system's performance and the product's cost. This paper analyzes the hardware design techniques that efficiently contribute to the realization of fault management and, consequently, guarantee a high level of reliability and availability for the services offered to the end customer. We describe hardware requirements and how they affect the choice of devices in the hardware design of networking systems.
