relabel don't find label

[Kordován Szabolcs]

Hi All,

I would like to modify a label but it seems that prometheus doesn't find the label. I have checked the source of the relabel, I found nothing.

The metric:

zxAnGponRmAniRxOptLevel{ifDescr="gponxxxxx", ifIndex="285278721", instance="xxx.xxx.xxx.xxx:yyyyy", job="query", zxAnGponOnuMgmtRegistrationInfo="1,ZTEGXXXXXXXX", zxAnGponRmAniIndex="1", zxAnPonOnuIndex="2"}

3661

The config:

    relabel_configs:

      - source_labels: [zxangpononumgmtregistrationinfo]
        regex: .*,(.*)
        replacement: "$1"
        target_label: "SN"

Do you have any idea?

You need to use metric_relabel_configs, not relabel_configs.

* relabel_configs is run for the target relabelling phase, before scraping.  It can be used to modify the address and port being scraped.

* metric_relabel_configs is run after scraping.  It can be used to modify or drop the metrics returned by the scrape.

Also, I believe the label names are case-sensitive.
