Install Prometheus on Ubuntu 24.04
Step 1:
Set up the Prometheus Server and install [node-exporter] to collect metric data on system resources, such as CPU or memory usage.
sudo apt -y install prometheus prometheus-node-exporter

Step 2:
Set up the basic configurations in [prometheus.yml].
1. Open the prometheus.yml
configuration file:
sudo cat /etc/prometheus/prometheus.yml
Output
# Sample config for Prometheus.
global:
scrape_interval: 15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.
# scrape_timeout is set to the global default (10s).
# Attach these labels to any time series or alerts when communicating with
# external systems (federation, remote storage, Alertmanager).
external_labels:
monitor: 'example'
# Alertmanager configuration
alerting:
alertmanagers:
- static_configs:
- targets: ['localhost:9093']
# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
rule_files:
# - "first_rules.yml"
# - "second_rules.yml"
# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
scrape_configs:
# The job name is added as a label `job=` to any timeseries scraped from this config.
- job_name: 'prometheus'
# Override the global default and scrape targets from this job every 5 seconds.
scrape_interval: 5s
scrape_timeout: 5s
# metrics_path defaults to '/metrics'
# scheme defaults to 'http'.
static_configs:
- targets: ['localhost:9090']
- job_name: node
# If prometheus-node-exporter is installed, grab stats about the local
# machine by default.
static_configs:
- targets: ['localhost:9100']
Configure system services on Linux to start automatically at boot
sudo systemctl enable prometheus prometheus-node-exporter

Step 3:
From a client host, access [http://(Prometheus server's hostname or IP address):9090/
]. The Prometheus Web UI will appear as shown below.

Step 4:
Click on [insert metric at cursor] to view various time series data queries. You can also directly input queries in the form above using Prometheus [Expression Language].
Refer to the official document about usage of Expression Language.
