Shulou(Shulou.com)06/01 Report--

This article will explain in detail how to build monitoring in Prometheus. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

Prometheus (Prometheus)

Lab environment: (each host, ip, required services)

Docker01 docker02 docker03

1.10 1.20 1.30

NodeEXporter NodeEXporter NodeEXporter

CAdvisor cAdvisor cAdvisor

Prometheus Server

Grafana

Turn off all firewalls and disable selinux.

[root@docker01 ~] # systemctl stop firewalld

[root@docker01 ~] # systemctl disable firewalld

[root@docker01 ~] # setenforce 0

Setenforce: SELinux is disabled

Components need to be deployed:

Prometheus Server: the main server of Prometheus.

NodeEXporter: responsible for collecting Host hardware information and operating system information.

CAdvisor: responsible for collecting container information running on Host.

Grafana: responsible for displaying the Prometheus monitoring interface.

1. Import Mirror

Docker01:

[root@docker01 ~] # docker load

< mycadvisor.tar && docker load < grafana.tar && docker load < node-exporter.tar && docker load < prometheus.tar docker02: [root@docker02 ~]# docker load < mycadvisor.tar && docker load < node-exporter.tar docker03:

[root@docker03 ~] # docker load < mycadvisor.tar & & docker load < node-exporter.tar

Mirror pull complete!

1) 3 nodes, all deploy node-EXporter and cAdvisor.

Do it all on PS:3, go to the browser for verification.

Deploy node-EXporter to collect hardware and system information

[root@docker01 ~] # docker run-d-p 9100vis9100-v / proc:/host/proc-v / sys:/host/sys-v /: / rootfs-- net=host prom/node-exporter-- path.procfs / host/proc-- path.sysfs / host/sys-- collector.filesystem.ignored-mount-points "^ / (sys | proc | dev | host | etc) ($| /)

PS: notice that-- net=host is used here so that Prometheus Server can communicate directly with Node-Exporter.

Verification: open the browser verification result: ip plus port 9100:

/ / deploy and install cAdvisor. Collect node container information.

Do it all on PS:3, go to the browser for verification.

[root@docker01] # docker run-v /: / rootfs:ro-v / var/run:/var/run/:rw-v / sys:/sys:ro-v / var/lib/docker:/var/lib/docker:ro-p 8080pur808080-- detach=true-- name=cadvisor-- net=host google/cadvisor

After the deployment is completed, the browser accesses: IP plus port 8080:

2) deploy the Prometheus Server service on docker01.

Before deploying Prometheus, we need to modify its configuration file, so let's run a container and copy its configuration file first.

[root@docker01] # docker run-d-p 9090 name prometheus-- net=host prom/prometheus

[root@docker01 ~] # docker cp prometheus:/etc/prometheus/prometheus.yml. /

[root@docker01 ~] # vim prometheus.yml

Change line 28 to:

-targets: ['localhost:9090','localhost:8080','localhost:9100','192.168.1.20:8080','192.168.1.20:9100','192.168.1.30:8080','192.168.1.30:9100']

Ip, port of each node

PS: the monitoring items of prometheus are established here, including that it also monitors the data collected by itself.

[root@docker01] # docker rm-f prometheus

Prometheus

[root@docker01] # docker run-d-p 9090 name prometheus-- net=host-v / root/prometheus.yml:/etc/prometheus/prometheus.yml prom/prometheus

Internet access authentication: docker01 ip plus port 9090:

PS: you can check our various monitoring items here.

After suspending docker02:

After continuing to run docker02:

3) on docker01, deploy the grafana service to display the data collected by prometheus.

[root@docker01 ~] # mkdir grafana-storage

[root@docker01] # chmod 777-R grafana-storage/

[root@docker01] # docker run-d-p 3000 GF_SECURITY_ADMIN_PASSWORD=123.com 3000-name grafana- v / root/grafana-storage:/var/lib/grafana-e "GF_SECURITY_ADMIN_PASSWORD=123.com" grafana/grafana

Browser access authentication:

Account: admin

Password: 123.com

PS: see this, indicating that the prometheus and grafana services are connected normally.

At this time, although granfana collected the data, but how to display it is still a problem, gafana supports custom display information, but it is very troublesome to customize, but fortunately, granfana officially provides us with some templates for us to use.

Granfana official website:

Https://grafana.com/docs/grafana/latest/

Select a template, and then we have 2 ways to apply this template.

The first way: use the template through the JSON file.

After the download is complete, put it on the desktop and go to the grafana console

The second way to import templates:

You can use the ID number of the template directly.

Template ID:

With 10619

Go back to the grafana console.

Accident:

Bring your own template:
