通过之前的文章，我们做到了Grafana的安装部署和初期的设置，没有了解过的同学可以参考下面的文章链接

接下来要做的是数据可视化的一个应用，nginx访问文件的监控，输出图表。
如果你没有进行额外的配置，那么你的nginx日志是这样的
101.254.141.164 - - [19/Jul/2019:11:22:03 +0800] "GET /online/cart/info HTTP/1.1" 200 120 "https://servicewechat.com/wx855bd11a98860d4e/devtools/page-frame.html" "Mozilla/5.0 (iPhone; CPU iPhone OS 10_2 like Mac OS X) AppleWebKit/602.3.12 (KHTML, like Gecko) Mobile/14C92 Safari/601.1 wechatdevtools/1.02.1905151 MicroMessenger/6.7.3 Language/zh_CN webview/"

接下来修改配置文件，让日志记录更多信息
找到你的nginx
[root@VM_0_15_centos conf]# whereis nginx
nginx: /usr/local/nginx /usr/local/nginx/sbin/nginx
找到配置文件
[root@VM_0_15_centos conf]# cd /usr/local/nginx/conf

##If you have a lot of static files to serve through Nginx then caching of the files' metadata (not the actual files' contents) can save some latency.

########################## vhost #############################
include vhost/*.conf;
}
在上面的配置文件中我已经把日志配置加了进去，为了方便辨认再贴一遍
在http中添加对应日志配置->
log_format main '$remote_addr - $remote_user [$time_local] "$request" $http_host '
'$status $request_length $body_bytes_sent "$http_referer" '
'"$http_user_agent" $request_time $upstream_response_time’;
上面的配置的意思是增加一个main的日志配置
接下来将nginx.conf的server中的access_log /data/wwwlogs/access_nginx.log combined;
combined 替换为main,combined为nginx内置的不需要配置的默认文件格式。
vhost里的所有文件也要进行替换。
重启nginx
再查看日志，就变成了
101.254.141.164 - - [19/Jul/2019:11:38:36 +0800] "GET /online/item/list?page=1&count=10 HTTP/1.1" api4621d373.henibox.com 200 587 619 "https://servicewechat.com/wx855bd11a98860d4e/0/page-frame.html" "Mozilla/5.0 (Linux; Android 8.0.0; MIX Build/OPR1.170623.032; wv) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/68.0.3440.91 Mobile Safari/537.36 MicroMessenger/7.0.5.1440(0x27000537) Process/appbrand2 NetType/WIFI Language/zh_CN" 0.351 0.351

为了防止日志系统识别格式问题，可以将之前的日志文件转移到其他文件夹作为备份
在阿里云日志系统中添加一个项目，在项目中添加一个Logstore，然后接入配置向导
选择nginx访问日志
填写的日志格式就是我们之前修改的日志格式
选择需要应用的机器，这里作为测试选择测试机器
下一步就会自动识别文本，匹配对应的字段，并增加索引进行统计
到这一步，在阿里云日志服务的部分就完成了。
首先接入数据源，安装插件
cd /var/lib/grafana/plugins
git clone https://github.com/aliyun/aliyun-log-grafana-datasource-plugin
查看新增一个数据源
下一步开始配置
然后配置变量，配置变量用于在仪表盘页面公共选择时间段
我们用简单粗暴的引入方式，先直接引入阿里云官方给出的demo

注意上面的json文件，千万不要直接复制，这里需要修改的地方有两个，
一个是数据源，一定要改成自己前面配置的数据源的名称，不能用这个默认的
还有就是变量的域名部分，在这里直接改成自己的域名，就不用再去配置里的变量去改了
注意，由于这个官方的版本比较老，配置之后还存在字段兼容性的问题，需要按下面的进行修改
我们可以在仪表盘的配置界面直接修改json文件
经过修改json并保存之后，我们就得到了nginx访问日志的监控数据
我认为理解Grafana的点在于他是一个时序概念的数据可视化工具。
以后我会分享如何用它做业务相关的数据展示。
