Promethues如何针对站点、SSL监控
需求：使用监控插件名称：bloackbox exporter
bloackbox exporter 是prometheus社区提供的黑盒监控解决方案，运行用户通过HTTP、HTTPS、DNS、TCP以及ICMP的方式对网络进行探测(主动监测主机与服务状态)。
一、下载安装包部署
wget https://github.com/prometheus/blackbox_exporter/releases/download/v0.16.0/blackbox_exporter-0.16.0.linux-amd64.tar.gz
tar zxvf blackbox_exporter-0.16.0.linux-amd64.tar.gz
mkdir /usr/local/exporter
mv blackbox_exporter-0.16.0.linux-amd64 /usr/local/exporter/blackbox_exporter
/usr/local/exporter/blackbox_exporter/blackbox_exporter --config.file=/usr/local/exporter/blackbox_exporter/blackbox.yml配置文件
modules:
http_2xx:
prober: http
http_post_2xx:
prober: http
http:
method: POST
tcp_connect:
prober: tcp
pop3s_banner:
prober: tcp
tcp:
query_response:
- expect: "^+OK"
tls: true
tls_config:
insecure_skip_verify: false
ssh_banner:
prober: tcp
tcp:
query_response:
- expect: "^SSH-2.0-"
irc_banner:
prober: tcp
tcp:
query_response:
- send: "NICK prober"
- send: "USER prober prober prober :prober"
- expect: "PING :([^ ]+)"
send: "PONG ${1}"
- expect: "^:[^ ]+ 001"
icmp:
prober: icmp访问：http://xxxx:9115/
制作system启动文件（可忽略）
[root@Prometheus exporter]# cd /usr/lib/systemd/system
# 配置blackbox的开机自启文件
[root@Prometheus system]# cat blackbox_exporter.service
[Unit]
Description=blackbox_exporter
After=network.target
[Service]
User=prometheus
Group=prometheus
WorkingDirectory=/usr/local/exporter/blackbox_exporter
ExecStart=/usr/local/exporter/blackbox_exporter/blackbox_exporter
[Install]
WantedBy=multi-user.target
# 启动
[root@node00 system]# systemctl restart blackbox_exporter
# 查看状态
[root@node00 system]# systemctl status blackbox_exporter
# 开机自启
[root@node00 system]# systemctl enable blackbox_exporter二、配置promethus采集数据，修改promethus-server配置文件，监控URL地址
- 方法一 、修改promethus-server的配置文件,添加blackbox_http_2xx (url直接写在文件中) /usr/local/prometheus/prometheus.yml
- job_name: 'blackbox_http_2xx'
scrape_interval: 45s
metrics_path: /probe
params:
module: [http_2xx] # Look for a HTTP 200 response.
static_configs:
- targets:
- https://www.baidu.com/
- 172.0.0.1:9090
- https://www.qq.com
relabel_configs:
- source_labels: [__address__]
target_label: __param_target
- source_labels: [__param_target]
target_label: instance
- target_label: __address__
replacement: 114.67.116.119:9115重启动promethus服务
展示最近监控信息
- 方法二、修改promethus-server的配置文件,添加blackbox_http_2xx (url单独写一个规则文件) /usr/local/prometheus/prometheus.yml
- job_name: "blackbox_http_file_test"
metrics_path: /probe
params:
module: [http_2xx] # Look for a HTTP 200 response.
file_sd_configs:
- refresh_interval: 1m
files:
- "/usr/local/prometheus/conf/blackbox*.yml"
relabel_configs:
- source_labels: [__address__]
target_label: __param_target
- source_labels: [__param_target]
target_label: instance
- target_label: __address__
replacement: 114.67.116.119:9115URL规则文件
[root@node00 prometheus]# cat conf/blackbox-dis.yml
- targets:
- https://www.alibaba.com
- https://www.tencent.com
- https://www.baidu.com重启动promethus服务
三、grafana展示blackbox采集数据
- 1、 选择--》import-->通过导入9965，获取监控展示模板。
- 2、站点监控，域名监控、域名到期监控展示
四、错误提示 Panel plugin not found: grafana-piechart-panel
解决方法
[root@Prometheus ~]# grafana-cli plugins install grafana-piechart-panel
installing grafana-piechart-panel @ 1.4.0
from: https://grafana.com/api/plugins/grafana-piechart-panel/versions/1.4.0/download
into: /var/lib/grafana/plugins
✔ Installed grafana-piechart-panel successfully
Restart grafana after installing plugins . <service grafana-server restart>本文参与 腾讯云自媒体同步曝光计划，分享自微信公众号。
