• 配置db連接

• 配置Templating

  • 舉例 Variables：不同域名 SHOW TAG VALUES FROM table WITH KEY = "host"

• 配置圖表

  • 選擇圖表連接DB
  • SELECT sum("requests") AS "請(qǐng)求總數(shù)", sum("status_2xx") AS "2xx", sum("status_3xx") AS "3xx", sum("status_4xx") AS "4xx", sum("status_5xx") AS "5xx" FROM "autogen"."table" WHERE "domain" =~ /^$uri_domain$/ AND "host" =~ /^$host$/ AND $timeFilter GROUP BY time(5m)

• 導(dǎo)入數(shù)據(jù)到表中
