Today, the editor will bring you an article about node monitoring based on prometheus11-k8s-node. The editor thinks it's pretty good, so I'll share it for you as a reference. Let's follow the editor and have a look.

1.node contact deployment node_exporter

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

2. Promethesus users start the addition of each user

Mv node_exporter-0.18.1.linux-amd64 / usr/local/node_ exporter [root @ zabbix-server system] # cat node_ exporter.service [unit] Description=node_exporterDocumentation= https://prometheus.io/After=network.target[Service]Type=simpleUser=prometheusExecStart=/usr/local/node_exporter/node_exporterRestart=on-failure[Install]WantedBy=multi-user.target[root@zabbix-server system] # pwd/usr/lib/systemd/systemsystemctl daemon-reloadsystemctl start node_exporter

3. View metrics

4. Edit the configuration file of prometheus and use

Prometheus-configmap.yamlkubectl apply-f prometheus-configmap.yaml

5. View prometheus Monitoring

6. Add template 9276

7. Add

8. Check the dashboard some values do not come out of their own edit options can be adjusted will come out

Note:

For several SQL of prometheus, it is recommended to write down the CPU utilization in front of the above figure: 100-(avg (irate (node_cpu_seconds_total {mode= "idle"} [5m])) by (instance) * 100) memory utilization: 100-(node_memory_MemFree_bytes+node_memory_Cached_bytes+node_memory_Buffers_bytes) / node_memory_MemTotal_bytes * 100 disk utilization: 100-(node_filesystem_free_bytes {mountpoint= "/") Fstype=~ "ext4 | xfs"} / node_filesystem_size_bytes {mountpoint= "/", fstype=~ "ext4 | xfs"} * 100)

The above are the details of node monitoring based on prometheus11-k8s-node, and the detailed usage needs to be used by everyone through hands-on experiments. If you want to know more, you are welcome to follow the industry information channel!
