整理结果时比较浪费时间。
在 GUI 用插件看曲线，做高并发时并不现实。
在场景运行时间比较长的时候，采用生成 HTML 的方式，会出现消耗内存过大的情况，而实际上，在生成的结果图中，有很多生成的图我们并不是那么关注。
生成的结果保存之后再查看比较麻烦，还要一个个去找。

// FOR ALL STATUS

// FOR OK STATUS
addMetric(transaction, metric.getSuccesses(), null, null, TAG_OK, metric.getOkMean(), metric.getOkMinTime(),
metric.getOkMaxTime(), okPercentiles.values(), metric::getOkPercentile);
