有人可以告诉我什么是grafana "series name column"？

Question

我应该在 <Series name column> 中输入什么？

我正在尝试做一个饼图仪表板，但我不知道在哪里可以看到相关信息。

SELECT
  UNIX_TIMESTAMP(<time_column>) as time_sec,
  <value column> as value,
  <series name column> as metric
FROM <table name>
WHERE $__timeFilter(time_column)
ORDER BY <time_column> ASC

Answer 1

例如，您有一个 table，其中包含列 'server_name'、'cpu_load'、'reported_time'。所以你可以使用

来查询

SELECT
  UNIX_TIMESTAMP(reported_time) as time_sec,
  cpu_load as value,
  server_name as metric
FROM cpu_measurements
WHERE $__timeFilter(reported_time)
ORDER BY time_sec ASC
