/api/stats/query

该端点可用于跟踪和疑难解答针对 TSD 执行的查询。它维护着一个无限制的当前正在执行的查询列表，以及一个多达 256 个已完成查询的列表(将最旧的查询从内存中移出)。有关每个查询的信息包括原始查询，请求 Headers，响应代码，时间安排和抛出异常。 (v2.2)

Requests

无可用参数。

Example Request

Query String

http://localhost:4242/api/stats/query

Response

响应包括两个数组。 completed列出成功完成或出错的 256 条最近执行完毕的查询。 running数组包含当前正在执行的查询的列表。如果此列表不断增加，则 TSD 负担沉重。请注意，运行列表将不包含异常，响应代码或时序详细信息。
