- 1.安装go环境
- 2.安装openvpn_exporter
- 3.设置OpenVPN服务器状态日志文件的路径
- 4.编译成openvpn_exporter
- 5.修改prometheus
- 6.添加模版
- 7.systemd启动
go下载地址: https://golang.org/dl/
openvpn_exporter下载地址:https://github.com/kumina/openvpn_exporter/releases
wget https://golang.org/dl/go1.15.2.linux-amd64.tar.gz tar -C /usr/local -xzf go1.15.2.linux-amd64.tar.gz #添加环境变量 vim ~/.bashrc #追后一行添加 PATH=$PATH:$HOME/bin:/usr/local/go/bin source ~/.bashrc2.安装openvpn_exporter
mkdir -p /opt/tools wget https://github.com/kumina/openvpn_exporter/archive/v0.3.0.tar.gz tar xzf v0.3.0.tar.gz cd openvpn_exporter-0.3.0/3.设置OpenVPN服务器状态日志文件的路径
vim main.og
...
func main() {
var (
listenAddress = flag.String("web.listen-address", ":9176", "Address to listen on for web interface and telemetry.")
metricsPath = flag.String("web.telemetry-path", "/metrics", "Path under which to expose metrics.")
// openvpnStatusPaths = flag.String("openvpn.status_paths", "examples/client.status,examples/server2.status,examples/server3.status", "Paths at which OpenVPN places its status files.")
openvpnStatusPaths = flag.String("openvpn.status_paths", "/etc/openvpn/server/openvpn-status.log", "Paths at which OpenVPN places its status files.")
...
4.编译成openvpn_exporter
go build -o openvpn_exporter main.go cp openvpn_exporter /usr/local/bin #有防火墙的放行或关闭 firewall-cmd --add-port=9176/tcp --permanent firewall-cmd --reload #简单测试 端口是9176 ./openvpn_exporter5.修改prometheus
vim /etc/prometheus/prometheus.yml
...
# The job name is added as a label `job=` to any timeseries scraped from this config.
- job_name: 'prometheus'
# metrics_path defaults to '/metrics'
# scheme defaults to 'http'.
static_configs:
...
## 监控openvpn
- job_name: 'openvpn-metrics'
scrape_interval: 5s
static_configs:
- targets: ['192.168.11.46:9176']
#重启prometheus
systemctl restart prometheus
6.添加模版
https://grafana.com/grafana/dashboards/10562 #通过执行以下命令安装Grafana饼图插件。 grafana-cli plugins install grafana-piechart-panel #重启grafana systemctl restart grafana-server.service7.systemd启动
