Editor to share with you how to integrate Prometheus Node Exporter, I believe that most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to understand it!

Brief introduction

Prometheus officials and some third parties have made the collection of some commonly used databases, systems, middleware and other index data into an exporter, which can be directly imported and used in the production environment. We use the Node Exporter officially provided by Prometheus to complete the collection of Linux system operation data.

Installation and Operation of Experimental NodeExporter

Download address: https://github.com/prometheus/node_exporter/releases

Download and extract:

Wget https://github.com/prometheus/node_exporter/releases/download/v0.18.1/node_exporter-0.18.1.linux-amd64.tar.gztar zxvf node_exporter-0.18.1.linux-amd64.tar.gz

Enter node_exporter-0.18.1.linux-amd64 to start nod

E_exporter:

. / node_exporterPrometheus configuration

Configure the metrics endpoint of node_exporter in prometheus.yml as follows:

Global: scrape_interval: 5s evaluation_interval: 5s timeout: 5sscrape_configs:-job_name: 'prometheus' static_configs:-targets: [' localhost:9090']-job_name: 'linux-exporter' metrics_path: / metrics static_configs:-targets: [' 172.16.2.101 evaluation_interval 9100']

Start prometheus:

Docker run-- name prometheus-d-p 9090 prom/prometheus 9090-v / root/prometheus-data:/prometheus-data\ prom/prometheus-- web.enable-lifecycle-- config.file=/prometheus-data/prometheus.yml

Visit http://172.16.2.101:9090/targets and find that target "node_exporter" has appeared and is in UP status.

Grafana Import DashBoard

Grafana officials and the community have already done the commonly used DashBoard. You can visit https://grafana.com/grafana/dashboards to query.

Select the one with the most downloads and click in:

The id of DashBoard is 8919, which will be used later.

Start Grafana

Docker start grafana

Import (Import) Node Exporter dashboard through the + icon of Grafana:

Grafana id = 2129

Note that the prometheus data source is selected

Click "Import" to jump to the monitoring interface:

Through the interface, you can directly see the host cpu occupancy, load, disk space, memory and other information.
