grafana 的安装
这里主要讲在Centos下的安装，其实这个网上到处是，其他系统我就不多说了。
wget https://s3-us-west-2.amazonaws.com/grafana-releases/release/grafana-4.2.0-1.x86_64.rpm
yum localinstall grafana-4.2.0-1.x86_64.rpm
#启动 granafa
systemctl start grafana-server
然后你查看，就能看到在运行了
netstat -tpnl | grep 3000
访问 http://ip:3000
帐号密码都是 admin
接入mysql数据源
点击 add data source 输入Mysql的连接信息 这样就添加好了

线图展示
- 点击 new dashboard
- 然后添加一个新的Dashboard Row
- 再在这个Row 里添加一个新的Panel 选择 Graph
总访问量(按项目)
从ngx_access表中根据不同project（也就是不同的nginx日志文件名）取出这个项目的总访问量
SELECT UNIX_TIMESTAMP(date) as time_sec,sum(times) as value,project as metric
FROM ngx_access
WHERE $__timeFilter(date)
group by project,date
ORDER BY date ASC
总访问量（按状态码）
从ngx_access表中根据不同code（也就是状态码）取出不同返回码的次数
SELECT
UNIX_TIMESTAMP(date) as time_sec,
sum(times) as value,
code as metric
FROM edu_access
WHERE $__timeFilter(date)
group by code,date
ORDER BY date ASC
响应时间排行
表格展示
- 点击 new dashboard
- 然后添加一个新的Dashboard Row
- 再在这个Row 里添加一个新的Panel 选择 Table
ip访问次数统计
做这个出来主要是看看时段内有没有大量的恶意访问
SELECT
ip as IP,
sum(times) as 次数
FROM ngx_ip
WHERE $__timeFilter(date)
GROUP BY ip ORDER BY 次数 DESC limit 100;|
PV（每日页面访问量）
SELECT
date_format(date, '%Y-%m-%d') as 日期,
sum(times) as value
FROM ngx_access
WHERE $__timeFilter(date)
group by date_format(date, '%Y-%m-%d')
ORDER BY date_format(date, '%Y-%m-%d') asc
IP（每日独立IP访问量）
SELECT
date_format(date, '%Y-%m-%d') as 日期,
count(distinct ip) as value
FROM ngx_ip
WHERE $__timeFilter(date)
group by 日期
ORDER BY 日期 asc
URL（URL的访问排行榜）
用于查看哪些功能（URL）被大量使用,这个感觉还比较有用，可以帮忙知道用户到底在干些什么。某些访问多的是不是该加机器或者独立之类的。
select
project as project,
url as url,
sum(times) as times
from ngx_access
WHERE $__timeFilter(date)
group by project,url
order by times desc limit 100
URL（响应时间排行）
根据每个project来展示每个URL 访问时间区间
SELECT
url as Url,
sum(xiaoyu10) as 小于10ms,
sum(xiaoyu50) as 10ms_50ms,
sum(xiaoyu100) as 50ms_100ms,
sum(xiaoyu500) as 100ms_500ms,
sum(dayu500) as 大于500ms,
sum(xiaoyu10+xiaoyu100+xiaoyu50+xiaoyu500+dayu500) as tatol
FROM edu_res
WHERE $__timeFilter(date) and project = 'project'
GROUP BY url ORDER BY tatol DESC limit 50;
