  • Production Practice:

falcon-agent one-click installation script

  • Study Skills:

Shell EOF use and add timed tasks

  • Script content:

Many of the three-party project machines in the isolation area are unmaintained, and there is no unified monitoring. It is necessary to converge all the basic monitoring to the company’s falcon monitoring, and get a one-click installation script to make the installation more convenient. Regardless of the robustness, it can be used.
