partners, users, and developers who plan to enhance scenario-specific capabilities. By creating a unified OS that supports multiple devices, openEuler hopes to enable a single application development for is built on the latest trends of interconnect buses and storage media, and offers a distributed, real-time acceleration engine and base services. It provides competitive advantages in edge and embedded deployments of online and offline cloud services. Its innovative CPU scheduling algorithm ensures real-time CPU preemption and jitter suppression for online services. Additionally, its innovative memory

ecosystem. openEuler is an innovative platform driven by community collaboration. It aims to build a unified and open OS that supports multiple processor architectures, and to advance the hardware and software In-depth optimizations for scheduling, I/O, and memory management • Tiered memory expansion etMem: unified management of various memory and storage media, and smooth expansion of system capacity • Live packets: It breaks the limitation of the TCP framework. This model adds an EDT timestamp to each data packet based on the scheduling policy, avoiding the delays caused by large queue buffers and bringing

and behavior of a system based on its external outputs, events, and data. It involves gathering and analyzing various types of data including logs, metrics, and traces in order to gain insights into a other issues. Paired with open source monitoring tools like OpenTelemetry, developers can gain real-time visibility of the system’s state and changes. Observability complements monitoring by providing application and infrastructure components while ensuring clear separation and control over changes in each layer of the system.

to set up Zabbix to monitor your environment, from setting up hosts to getting essential data to viewing data to configuring notifications and remote commands to be executed in case of problems. IT a fast reaction to server problems. Zabbix offers excellent reporting and data visualization features based on the stored data. This makes Zabbix ideal for capacity planning. Zabbix supports both polling single package. Data gathering • availability and performance checks • support for SNMP (both trapping and polling), IPMI, JMX, VMware monitoring • custom checks • gathering desired data at custom intervals
