如何让 REST API 请求更好？
使用普通的 URL 有点令人困惑。尤其是未加密的 &。我建议通过网络测试您的查询 UI: http://server02/graph.
你的 URL 看起来你想尝试 count(process_status<0.5)&{process_id=~"*fly*"}，但由于 URL 编码，它实际上是 count(process_status<0.5).
=~ 匹配器使用正则表达式。因此你必须写 process_id=~".*fly.*" 而不是 *fly*.
如果我没有正确理解你的问题，你的查询应该是这样的：
process_status{process_id=~".*fly.*"} < 0.5
文档也应该很清楚：https://prometheus.io/docs/prometheus/latest/querying/basics/
sum(process_status{process_id=~".*fly.*"} < bool 0.5)
Prometheus 使用正则表达式，而不是 glob。要处理没有匹配系列的情况，您需要使用 bool 修饰符 which returns 0/1 然后对其求和。使用 count 如果没有匹配的时间序列，您将得到任何结果（与 0 不同）。
