JMeter -- prometheus+grafana server performance visualization

1. Prometheus brief introduction

• Prometheus Is an open source system monitoring and alarm system , use go Language development , There are various exporter To collect server performance data

2. Prometheus Deploy

• Add configuration file

• Refer to ：https://github.com/prometheus/prometheus/blob/main/documentation/examples/prometheus.yml

vim prometheus.yml

# my global config
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).

# Alertmanager configuration
alerting:
  alertmanagers:
    - static_configs:
        - targets:
          # - alertmanager: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=<job_name>` to any timeseries scraped from this config.
  - job_name: "prometheus"

    # metrics_path defaults to '/metrics'
    # scheme defaults to 'http'.

    static_configs:
      - targets: ["localhost:9090"]

• establish prometheus Containers

docker run -d --name prometheus \
	--network grafana -p 9090:9090 \
	-v ${
    PWD}/prometheus.yml:/etc/prometheus/prometheus.yml \
	prom/prometheus:v2.16.0 --config.file=/etc/prometheus/prometheus.yml

• View monitoring status

• visit http://ip:9090/, choice Status–>Targets, You can view the list of monitored services

3. node_exporter Installation configuration

• node_exporter install

docker run -d --name node_exporter \
	-p 9100:9100 prom/node-exporter:v1.2.0

• Verify whether the tool service is started

• visit http://ip:9100, verification

• prometheus Configure adding monitored nodes

vim prometheus.yml
scrape_configs:
  - job_name: "prometheus"
    static_configs:
      - targets: ["localhost:9090"]

  # add
  - job_name: "demo01"      
    static_configs:
      - targets: ["ip:9100"] #  It can't be localhost

4. grafana visualization

• Create a container （ A little ）
• grafana Configure data sources

>+  visit grafana,http://ip:3000, Default password ：admin/admin
>+  Configuration database ：Add data source-->Prometheus-->
>   + Url: http://prometheus:9090( Same container Name and Port)
>   + Scrape interval:15s

• grafana Import Dashboard

>+ Import Dashboard
>   + Grafana.com Dashboard: 11174
>   + Name: Node Exporter for Prometheus
>   + Prometheus:Prometheus
