[TOC] ## 示例 ### 搜搜統計名 ``` {__name__=~"upantbiz_server_.*"} ``` 搜索所有upantbiz_server 開頭的配置 ### 簡單的時間序列選擇器 **直接搜索** ``` prometheus_http_requests_total ``` **條件搜索** ``` prometheus_http_requests_total{job="prometheus"} http_requests_total{status!~"4.."} ``` **復雜條件搜索** 選擇所有staging, testing, development環境且 HTTP 請求方法不是GET的http_requests_total時間序列 ``` http_requests_total{environment=~"staging|testing|development",method!="GET"} ``` **正則搜索** ``` http_requests_total{job=~".*server"} ``` 除4xxx 外的所有 ``` http_requests_total{status!~"4.."} ``` ### 平均速率 返回過去 30 分鐘的 http_requests_total 指標的 5 分鐘內的平均速率，分辨率為 1 分鐘. ``` rate(http_requests_total[5m])[30m:1m] ``` ### 時間向量茶香 ``` http_requests_total[5m] ``` 過去 5分鐘的值的列表 ``` http_requests_total offset 5m ``` 5分鐘前的某個值 ### 求平均值 ``` rate(http_requests_total[5m]) ``` 對過去5分鐘求平均值 ### 一對一向量匹配 樣本數據 ``` method_code:http_errors:rate5m{method="get", code="500"} 24 method_code:http_errors:rate5m{method="get", code="404"} 30 method_code:http_errors:rate5m{method="put", code="501"} 3 method_code:http_errors:rate5m{method="post", code="500"} 6 method_code:http_errors:rate5m{method="post", code="404"} 21 method:http_requests:rate5m{method="get"} 600 method:http_requests:rate5m{method="del"} 34 method:http_requests:rate5m{method="post"} 120 ``` 示例 ignoring關鍵字允許在匹配時忽略某些標簽 ``` method_code:http_errors:rate5m{code="500"} / ignoring(code) method:http_requests:rate5m ``` 輸出 ``` {method="get"} 0.04 // 24 / 600 {method="post"} 0.05 // 6 / 120 ```
