1、部署 prometheus

[root@mha ~]# tar -zxvf prometheus-2.32.1.linux-amd64.tar.gz

[root@mha ~]# cd prometheus-2.32.1.linux-amd64

[root@mha prometheus-2.32.1.linux-amd64]# ll

total 193448

-rwxr-xr-x 1 3434 3434 94996583 Dec 18 06:13 promtool

[root@mha prometheus-2.32.1.linux-amd64]# cp prometheus promtool /usr/local/bin/

[root@mha prometheus-2.32.1.linux-amd64]# prometheus --config.file "/etc/prometheus/prometheus.yml"

2、部署 node_exporter

[root@mha ~]# tar -xf node_exporter-1.3.1.linux-amd64.tar.gz

[root@mha ~]# cd node_exporter-1.3.1.linux-amd64

[root@mha ~]# mkdir -p /usr/local/node_exporter/textfile_collector

3、运行

[root@mha ~]# node_exporter --collector.textfile.directory="/usr/local/node_exporter/textfile_collector" --collector.systemd --collector.systemd.unit-whitelist="{docker|ssh|rsyslog|nginx}.service" --web.telemetry-path="/node_metrics"

4、过滤收集器

[root@mha ~]# more /etc/prometheus/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.

# Alertmanager configuration

alerting:

alertmanagers:

- static_configs:

- targets:

# - alertmanager:9093

rule_files:

# - "first_rules.yml"

# - "second_rules.yml"

scrape_configs:

- job_name: "prometheus"

static_configs:

- targets: ["localhost:9090"]

- job_name: "node"

static_configs:

- targets: ["192.168.26.182:9100", "192.168.26.181:9100", "192.168.26.180:9100"]

params:

collect[]:

- cpu

- meminfo

- diskstats

- netdev

- netstat

- filefd

- filesystem
