IPMI agent To get important data from hardware, a Zabbix server supports IPMI agents, which are present by default on Intel architecture servers like HP iLO and Dell DRAC.
The items available through IPMI agents vary in each hardware, but these are the most common:
Temperature of the CPU and chassis Fan speed System voltages State of the physical disk Maintenance LED status
warning CS8632: The annotation for nullable reference types should only be used in code within a '#nullable' annotations context.
이 경우에는 아래와 같이 #nullable 어노테이션 컨텍스트를 이용해서 알려주면 경고가 뜨지 않게 된다.

using (var reader = new StringReader(manyLines))

do {
item = reader.ReadLine();
Console.WriteLine(item);

Bluetooth® Classic The Bluetooth Classic radio, also referred to as Bluetooth Basic Rate/Enhanced Data Rate (BR/EDR), is a low power radio that streams data over 79 channels in the 2.4GHz unlicensed industrial, scientific, and medical (ISM) frequency band. Supporting point-to-point device communication, Bluetooth Classic is mainly used to enable wireless audio streaming and has become the standard radio protocol behind wireless speakers, headphones, and in-car entertainment systems. The Bluetooth Classic radio also enables data transfer applications, including mobile printing.
Bluetooth® LE The Bluetooth LE radio is designed for very low power operation. Transmitting data over 40 channels in the 2.4GHz unlicensed ISM frequency band, the Bluetooth LE radio provides developers a tremendous amount of flexibility to build products that meet the unique connectivity requirements of their market. Bluetooth LE supports multiple communication topologies, including point-to-point, broadcast and mesh. While initially known for its device communications capabilities, Bluetooth LE is now also widely used as a device positioning technology to address the increasing demand for high accuracy location services. Bluetooth LE now includes features that enable one device to determine the presence, distance, and direction of another device.
