wget https://github.com/prometheus/prometheus/releases/download/v2.45.0/prometheus-2.45.0.linux-amd64.tar.gz

 

  

 

Unzip.

tar xvfz prometheus-2.45.0.linux-amd64.tar.gz

 

Start the prometheus server with the command

 

local host connected to the server.

 

INSTALL NODE EXPORTER

Copy the link address:

wget https://github.com/prometheus/node_exporter/releases/download/v1.6.0/node_exporter-1.6.0.linux-amd64.tar.gz

unzip the binary.

tar xvfz node_exporter-1.6.0.linux-amd64.tar.gz

Now start node.

./node_exporter

Adding node exporter scrap_configs to prometheus as a YAML Configuration

Code:
./node_exporter
global:
scrape_interval: 15s
scrape_configs:
- job_name: node
static_configs:
- targets: ['localhost:9100']

 

 

Start the Prometheus server bypassing scrap_config with the help of –config.file flag

 

./prometheus --config.file=exporter-config.yml

 Node is up.
