分析网站访问情况

1. 登录云日志服务控制台。
2. 在左侧导航栏中选择“仪表盘 ”。
3. 在仪表盘模板下方，选择“采集诊断仪表盘模板>ICAgent整体状态”仪表盘，查看图表详情。

ICAgent整体状态仪表盘中的重要图表说明如下所示：

• 活跃ICAgent数图展示常用日志流的变化情况，所关联的查询分析语句如下所示：

  select diff[1] as "活跃ICAgent数",case when diff[2] is not null then diff[2] else '昨日无数据' end as "昨日活跃ICAgent数" from  (select report_topic,compare(uv,86400) as diff from (SELECT   report_topic,COUNT(DISTINCT ip) as uv FROM log where report_topic = 'icagent_status' group by report_topic) group by report_topic)

• 发送延迟/次数趋势图展示延迟/次数变化情况，所关联的查询分析语句如下所示：

  select time_floor(__time,'PT5M') as \"time\" , sum(\"metric.lts_cost.below_100_ms\") as \"below_100_ms\" , sum(\"metric.lts_cost.100to500ms\") as \"100to500ms\" , sum(\"metric.lts_cost.500msto1s\") as \"500msto1s\" , sum(\"metric.lts_cost.1sto10s\") as \"1sto10s\", sum(\"metric.lts_cost.10ston\") as \"10ston\" from log where \"report_topic\" = 'icagent_status' group by \"time\"

• 运行状态分布图展示运行状态的变化情况，所关联的查询分析语句如下所示：

  select status,count(DISTINCT ip) as pv from log where report_topic = 'icagent_status' group by status

• CPU趋势图展示CPU占用率的变化情况，所关联的查询分析语句如下所示：

  select ip,time_floor(__time,'PT5M') as \"time\",avg(\"metric.cpu_usage\") as \"CPU占用率\" from log where report_topic = 'icagent_status' and \"metric.cpu_usage\" is not null group by \"time\",ip order by \"time\"

• ICAgent整体状态图展示主机的整体情况，所关联的查询分析语句如下所示：

  select host_name as "主机名",ip as "IP" , version as "版本号" , os as "操作系统" , time_format(MILLIS_TO_TIMESTAMP(ANY_VALUE("metric.start_time")),'yyyy/MM/dd HH:mm:ss ZZZ') as "启动时间",avg("metric.cpu_usage") as "CPU",avg("metric.mem_used")*1.0 as "内存(MB)",status as "运行状态" where report_topic = 'icagent_status' group by host_name,ip,version,os,status
