TCP 测试： 业务组件端口状态监听、应用层协议定义与监听
ICMP 测试： 主机探活机制
POST 测试： 接口联通性
SSL证书过期时间二、blackbox_exporter安装
# wget https://github.com/prometheus/blackbox_exporter/releases/download/v0.16.0/blackbox_exporter-0.16.0.linux-amd64.tar.gz
# tar xf blackbox_exporter-0.16.0.linux-amd64.tar.gz -C /usr/local/
# ln -s /usr/local/blackbox_exporter-0.16.0.linux-amd64/ /usr/local/blackbox_exporter
# 使用systemd进行管理blackbox_exporter服务
# vim /usr/lib/systemd/system/blackbox_exporter.service
[Unit]
Description=blackbox_exporter
After=network.target
[Service]
User=root
Type=simple
ExecStart=/usr/local/blackbox_exporter/blackbox_exporter --config.file=/usr/local/blackbox_exporter/blackbox.yml
Restart=on-failure
[Install]
WantedBy=multi-user.target
# systemctl daemon-reload
# systemctl start blackbox_exporter.service
# systemctl enable blackbox_exporter.service
三、配置prometheus采集数据
# cd /usr/local/prometheus
# vim prometheus.yml
# my global config
global:
scrape_interval: 15s
evaluation_interval: 15s
alerting:
alertmanagers:
- static_configs:
- targets:
rule_files:
# - "first_rules.yml"
# - "second_rules.yml"
scrape_configs:
- job_name: ‘prometheus‘
static_configs:
- targets: [‘192.168.5.237:9090‘]
- job_name: ‘node‘
file_sd_configs:
- refresh_interval: 30s
files:
- "/usr/local/prometheus/sd_config/node*.yml"
- job_name: ‘docker‘
static_configs:
- targets: [‘192.168.5.85:8080‘]
- job_name: ‘mysql‘
static_configs:
- targets: [‘192.168.5.237:9104‘]
labels:
app: zabbix-server-mysql
# 网站监控
- job_name: ‘http_status‘
metrics_path: /probe
params:
module: [http_2xx]
static_configs:
- targets: [‘http://www.lzfn.com‘, ‘wiki.lzfn.com‘]
labels:
instance: http_status
group: web
relabel_configs:
- source_labels: [__address__]
target_label: __param_target
- target_label: __address__
replacement: 192.168.5.85:9115
# ping 检测
- job_name: ‘ping_status‘
metrics_path: /probe
params:
module: [icmp]
static_configs:
- targets: [‘192.168.5.85‘]
labels:
instance: ‘ping_status‘
group: ‘icmp‘
relabel_configs:
- source_labels: [__address__]
target_label: __param_target
- target_label: __address__
replacement: 192.168.5.85:9115
# 端口监控
- job_name: ‘port_status‘
metrics_path: /probe
params:
module: [tcp_connect]
static_configs:
- targets: [‘192.168.5.85:80‘, ‘192.168.5.85:9000‘, ‘192.168.5.85:8080‘]
labels:
instance: ‘port_status‘
group: ‘port‘
relabel_configs:
- source_labels: [__address__]
target_label: __param_target
- target_label: __address__
replacement: 192.168.5.85:9115
# 检查配置文件并重启服务
# ./promtool check config prometheus.yml
Checking prometheus.yml
SUCCESS: 0 rule files found
# systemctl restart prometheus.service四、配置Grafana展示数据
grafana-cli plugins install grafana-piechart-panel
systemctl restart grafana-server.service
