systemctl start grafana-server

cd /var/lib/grafana/plugins/

systemctl restart grafana-server

ip:3000 访问

![70 1][]

默认帐号密码是admin admin

点击data source 添加elasticsearch 数据源

![70 2][]

name：数据源名称。本样例值：es-leo-nginx。

Type：数据源类型，这里选择Elasticsearch。

URL：是Elasticsearch服务器的URL

Index name：索引名称。

Pattern：选择Daily

Time field name：时间字段（注意这里的时间不要是字符串格式必须是时间格式）

Version：选择你安装的相应的版本。

之后保存之后 去创建dashboard

![70 3][]

![70 4][]

Min time interval：设置为5s获取一次

Query：Lucence查询语法，跟kibana的查询一样，我这里统计loglevel键对应value是DEUG 并且 host等于$HOST的数量

Alias：设置为别名

![70 5][]

Stat：选择统计值

background设置背景色

Thresholds：根据vlaue的大小决定颜色，设置最大值以及最小值

按照上面的步骤继续创建采集info等其他等级的数量

之后创建pie chart用于可视化统计百分比

![70 6][]

![70 7][]

这里要注意设置options 默认不会取total的值 需要手动改成total

![70 8][]

现在讲下$HOST的设置，如何去设置variables ：

那为什么要设置这个变量呢，因为如果你有一大批分组 分类的日志，如果你一个一个加的话非常麻烦而且看起来很臃肿。如果设置了variables  也就是模版这样只需要操作一次图形设计就可以查看不同分类的日志

![70 9][]

![70 10][]

![70 11][]

name：定义变量名

label：标签名

Data source 选择数据源

Query：必须json格式 获取对应的变量值 详情见[http://docs.grafana.org/features/datasources/elasticsearch/][http_docs.grafana.org_features_datasources_elasticsearch]

设置完成保存之后 会在Dashboards看到一下列表
