Monitoring：Using Scripts to Monitor Linux Operating System

Preparation

To monitor the local machine, simply deploy Hertzbeat. To monitor other hosts, you need to deploy a collector on the target host. Refer to this link for step 5 of the installation process. When creating a monitoring task and selecting a collector, choose the corresponding collector deployed on the target host.
