我想获取值＆lt; 0.5和name process_id满足掩码 fly
http://server02/api/v1/query_range?query=count(process_status<0.5)&{process_id=~"*fly*"}&start=1516627862.0&end=1516631462.0&step=60
但结果并不好。 如何使REST API请求更好？
答案 0 :(得分：0)
使用普通URL有点令人困惑。尤其是未展开的&。我建议您通过网络用户界面测试您的查询：http://server02/graph。
您的网址似乎要尝试count(process_status<0.5)&{process_id=~"*fly*"}之类的内容，但由于网址编码实际上是count(process_status<0.5)。
=~匹配器使用正则表达式。因此，您必须撰写process_id=~".*fly.*"而不是*fly*。
如果我正确理解了您的问题，您的查询应如下所示：
process_status{process_id=~".*fly.*"} < 0.5
此外，文档应该非常明确：https://prometheus.io/docs/prometheus/latest/querying/basics/
答案 1 :(得分：0)
bool Prometheus使用正则表达式而不是globs。要处理没有匹配系列的情况，您需要使用返回0/1的count修饰符然后求和。如果没有时间序列匹配，使用IsChecked将得到任何结果（与0不同）。
