Go Data Collector Test

Testing various Go packages and their support for collecting system information

Purpose

The purpose of this project is to determine what the best library there is to pull system information on a variety of systems. After completing some tests, I will be picking a library which I will be using in an upcoming health monitoring project.

Criteria

I will only be testing on Mac but the ideal library will have support for Windows/Linux/Mac (any additional OS support is a bonus). Linux support is the most crucial.

Each library should have extensive support for getting basic system information (CPU, OS, Total Memory, etc.) as well as extensive support for getting more detailed system information (processes, network info., memory usage, etc.)

Libraries being tested

gopsutil

go-sysinfo

Notes

• This code is sloppy but it serves a purpose. The extra time to cleanup the code simply wasn't worth it for a project like this.
• The data isn't one-to-one mapped so it requires a bit more investigation when trying to figure out what's supported via each library.

Conclusion

Initially, I started out with 5 libraries to test. In the end, I ended up testing 2 libraries and once was the clear winner. I had planned on exporting the output so it's easier to read and compare but the exercise of implementing the required features and further looking into the documentation for other features resulted in a clear winner. For my use case, gopsutil ended up being the best fit and this is further cemented by the amount of similar Go utilities that use this package. While I liked go-sysinfo, it simply lacked the amount of details provided by gopsutil and lacked the bonus features like gopsutil has.
