Hi everyone, can anyone here help me to setup Prometheus for monitor Linux Server (80+ LInuxclient) Or can anyone share the guideline for network and system monitoring. After some research I had configured and Its Showing some status, but don’t know how to monitor network bandwidth, ram & hard disk uses and if I want to monitor my application, how can I setup any help will be helpful.

You can try node exporter , cadvisor exporter.
Configure these exporter on all Linux node. They expose the node metrics on port which you will configure while installing. Now you can scrap these exporters with Prometheus.
If you want you can have a centralised Prometheus which will scrap all exporters deployed on all Linux Machine.
