It has been two and a half months since I wrote a blog last time. I am also busy at work and lazy. I am also accumulating articles. Anyway, I haven’t written for a long time. This time I will share a component that uses Java to obtain cao operating system and hardware information. I was going to share it before the 11.11 holiday. However, there are many detailed parameters. The focus of this article is to list these parameters in detail, give personal understanding of the parameters and embarrassing translation results, and tap to spray.
This site has high expectations for the realization of blog 2.0, so the main management page in the background also plans to read and display some parameters of the server, which are not limited to Jdk and Web container parameters, but also include the cao operating system itself Some hardware parameters, this is the background.
Surrounding this background, we still collect related implementations. Among them, the implementations of Sigar and oshi seem to be more powerful, but the former needs to rely on the dynamic link library files of different cao operating systems to achieve. Whether the function is powerful or not is not shown for the time being. In my background here The next step is definitely to consider the implementation of oshi. Its implementation is cross-platform, and each parameter is implemented according to different cao operating systems. For some commonly used parameters, we do not need to call the underlying interface of the system. oshi is Java A free JNA-based (native) cao operating system and hardware repository. It does not require any other native libraries to be installed and aims to provide a cross-platform implementation to retrieve system information such as operating system version, processes, memory and CPU usage, disks and partitions, devices, sensors, etc., below All descriptions are around oshi .

Organize the parameters in detail (operatingSystemcao operating system, hardware motherboard), sorting out is too time-consuming, in fact, there are only a few useful ones, and then it is the most complete parameter sorting in all related articles you can see.
