Questions about custom labels for alerts

[243560834]

What did you do?

在prometheus.yml配置主机时在多个job_name下都添加了一个自定义label，但在alertmanager告警时只有个别主机的label出现在告警信息中，有些job_name的告警信息中就没有这个label，这是怎么回事

Hi,

We don't speak Chinese here sorry. Do you mind translating to English before submitting next time? I did it using Google translate for your first sentence and title.

When configuring the host in prometheus.yml, a custom label is added under multiple job_names. However, when the alertmanager generates an alarm, only the labels of individual hosts appear in the alarm information. The label is not included in the alarm information of some job_names. How is this? What's going on

Custom label.. do you mean external label section? Sharing your prometheus.yaml would help. AFAIK the external labels should be attached to all alerts by default.
