Prometheus 抓取错误 "expected timestamp or new record, got "MNAME"

Question

我已将 Prometheus 附加到我的指标 rest 端点，但我收到错误 "expected timestamp or new record, got "MNAME”。我的端点生成看起来

的响应正文

ElapsedScanTime_count {Subject="DEV-Product-1"} 0.563 
LiveActivities_count {Subject="DEV-Product-1"} 53 
LogEvents_count {Subject="DEV-Product-1"} 0 
LogEventsProcessed_count {Subject="DEV-Product-1"} 56717

我像下面这样结束每一行

string prometheusFormat = "";

foreach (var metric in metricsArray.Values)
   {
   prometheusFormat += metric .ToString () + " " + Environment.NewLine;
   }

Answer 1

以下示例应符合 Prometheus API 格式：

$ echo 'elapsed_scantime_count{Subject="DEV-Product-1"} 0.563' | ./promtool check metrics
elapsed_scantime_count no help text

移除驼峰式大小写，移除空格并以 \n

结束每行

此外，请勿在指标名称、标签或指标名称开头使用数字。

确保指标符合正则表达式 [a-zA-Z_:][a-zA-Z0-9_:]* 并且标签必须符合正则表达式 [a-zA-Z_][a-zA-Z0-9_]*
