(2) node_exporter deployment to monitor container hosts

To monitor CPU, memory, disk, I/O and other information of Kubernetes Engine, first install node_exporter. node_exporter is used for machine system data collection.

(1) Download node_exporter

https://prometheus.io/download/

shell> cd /Download/

shell> wget https://github.com/prometheus/node_exporter/releases/download/v0.18.1/node_exporter-0.18.1.linux-amd64.tar.gz

(2) Decompress installation

shell> tar -xvf node_exporter-0.18.1.linux-amd64.tar.gz

shell>cd node_exporter-0.18.1.linux-amd64

shell> mv node_exporter-0.18.1.linux-amd64 node_exporter

shell> chown -R prometheus.prometheus node_exporter

shell> systemctl restart node_exporter

shell>systemctl status node_exporter

shell>netstat -tunlp | grep node_exporter

(3) Create systemd service

shell>cat > /etc/systemd/system/node_exporter.service systemctl daemon-reload

shell> systemctl start node_exporter #Start node_exporter service

shell> systemctl status node_exporter

Add job to prometheus_server

shell> vim /Download/prometheus/prometheus.yml

job_name: 'docker39'

scrape_interval: 5s

static_configs:targets: ['10.10.204.39:9100']

labels:

shell>systemctl restart prometheus #Restart prometheus service

(5) Check whether the prometheus console gets the data
