Prometheus - 从 file_sd 配置地址创建一个新标签

Question

我有一些 file_sd 配置，其目标格式为 'ip hostname' 例如'10.10.11.12 富'

我需要将 foo 值提取到新标签“hostname”，然后将添加端口值“:9100”添加到 ip 并将其分配给 target_label:instance

我尝试使用下面的代码，但不幸的是它不起作用。

relabel_configs:
  - source_labels: [__address__]
    regex: '([^ ]+)'   
    target_label: instance
  - source_labels: [__address__]
    regex: '(.+)(.+)'  
    target_label: instance
    replacement: '${1}'
  - source_labels: [__address__]
    regex: '(.+)(.+)'  
    target_label: __address__
    replacement: '${2}'
  - source_labels: [__address__]
    target_label: __address__
    replacement: '${1}:9100'

终于解决了

relabel_configs:
  - source_labels: [__address__]
    regex: "(.+) (.+)"
    replacement: "$2"
    target_label: hostname
  - source_labels: [__address__]
    regex: "(.+) (.+)"
    replacement: "$1"
    target_label: "ip"
  - source_labels: [__address__]
    regex: "(.+) (.+)"
    replacement: "$1:9100"
    target_label: __address__
