我们使用nginx-clickhouse从Nginx收集日志，发送到Clickhouse并在Grafana中显示

我来自Luxoft。 本文将讨论nginx-clickhouse项目 ，该项目将读取nginx日志并将其发送到clickhouse。 要查看日志分析，有一个用于Grafana的仪表板。


以标准方式安装nginx，clickhouse，grafana。


所有软件包都安装在同一服务器上。


github上的Nginx-clickhouse页面


安装rpm软件包nginx-clickhouse


yum -y install yum-plugin-copr yum copr enable antonpatsev/nginx-clickhouse-rpm yum -y install nginx-clickhouse systemctl start nginx-clickhouse

作为HTTP服务的仿真器，我们使用模拟。


安装rpm模拟包


 yum -y install yum-plugin-copr yum copr enable antonpatsev/mockify-rpm yum -y install mockify systemctl start mockify

对于nginx-clickhouse，log_format具有以下形式。


 log_format main '$remote_addr - $remote_user [$time_local] "$request" $status $bytes_sent "$http_referer" "$http_user_agent"';

常规Nginx配置：


 user nginx; worker_processes auto; worker_rlimit_nofile 40960; error_log /var/log/nginx/error.log warn; pid /var/run/nginx.pid; events { use epoll; worker_connections 1024; multi_accept on; } http { include /etc/nginx/mime.types; default_type application/octet-stream; log_format main '$remote_addr - $remote_user [$time_local] "$request" $status $bytes_sent "$http_referer" "$http_user_agent"'; access_log /var/log/nginx/access.log main; sendfile on; tcp_nodelay on; tcp_nopush on; keepalive_timeout 65; include /etc/nginx/conf.d/*.conf; open_file_cache max=200000 inactive=20s; open_file_cache_valid 30s; open_file_cache_min_uses 2; open_file_cache_errors on; }

虚拟主机配置：


vhost1.conf：


 server { listen 80; server_name vhost1; location / { proxy_pass http://127.0.0.1:8001/200; } }

vhost2.conf：


 server { listen 80; server_name vhost2; location / { proxy_pass http://127.0.0.1:8001/200; } }

vhost3.conf：


 server { listen 80; server_name vhost3; location / { proxy_pass http://localhost:8001/304; } }

vhost4.conf：


 server { listen 80; server_name vhost4; location / { proxy_pass http://localhost:8001/401; } }

vhost5.conf：


 server { listen 80; server_name vhost5; location / { proxy_pass http://localhost:8001/500; } }

将虚拟主机添加到hosts文件：


 cat /etc/hosts 127.0.0.1 vhost1 127.0.0.1 vhost2 127.0.0.1 vhost3 127.0.0.1 vhost4 127.0.0.1 vhost5

Nginx-clickhouse配置默认为


 /etc/nginx-clickhouse/config/config.yml

日志的路径可以在配置中的以下参数中更改： log_path:


在Clickhouse中，您需要创建一个指标数据库：


 create database metrics

并且您需要创建一个nginx表：


 CREATE TABLE metrics.nginx ( RemoteAddr String, RemoteUser String, TimeLocal DateTime, Date Date DEFAULT toDate(TimeLocal), Request String, RequestMethod String, Status Int32, BytesSent Int64, HttpReferer String, HttpUserAgent String, RequestTime Float32, UpstreamConnectTime Float32, UpstreamHeaderTime Float32, UpstreamResponseTime Float32, Https FixedString(2), ConnectionsWaiting Int64, ConnectionsActive Int64 ) ENGINE = MergeTree(Date, (Status, Date), 8192)

在Grafana中，为Clickhouse创建数据源时，将其命名为ClickHouse Main Server ，因为 在Grafana的原始仪表板中，这就是他的名字。


您还需要创建一个包含metrics.nginx内容的表变量。

在Grafana官方网站上，您将找不到仪表板。 它是在这个封闭的问题中 ：


这是我经过稍微校正的仪表板：

使用Apache基准测试完成。


安装它：


 yum install -y httpd-tools

我们开始在不同的控制台中使用Apache基准测试：


 while true; do ab -c 1 -n 1 -t 1 http://vhost1/; sleep 2; done while true; do ab -c 1 -n 1 -t 1 http://vhost2/; sleep 2; done while true; do ab -c 1 -n 1 -t 1 http://vhost3/; sleep 2; done while true; do ab -c 1 -n 1 -t 1 http://vhost4/; sleep 2; done while true; do ab -c 1 -n 1 -t 1 http://vhost5/; sleep 2; done

结论：


我希望该项目能够进一步发展。 当项目处于非活动状态时。


如果您要手工组装项目，请注意此问题 。


电报频道：
Clickhouse
Nginx的
教会指标


读者的问题：如果将指标存储在Clickhouse中，那么您使用Nginx通过状态代码和虚拟主机获得哪些自托管实用程序/项目的指标？
