You mean you're seeing tag_owner, tag_Owner, tag_OWNER from different instances? Because the tags weren't entered consistently?
I don't see a lowercasing version of the "labelmap" action. So I think you're back to either: 1. fixing the data at source (e.g. using the EC2 API to read the tags and reset them to the desired values; and then make policies and procedures so that new instances have consistent tag names); or 2. proxying / modifying the exporter > I think lower/upper action in relabeling works to make "*values*" of labels to lower/upper I believe so. The way I interpret it, "lowercase" action is the same as "replace", but the concatenated values from source_labels are lowercased first. Hence the fixed target_label that you specify will get the lowercased value, after any regex matching/capturing. The test case here agrees: https://github.com/prometheus/prometheus/blob/v2.45.4/model/relabel/relabel_test.go#L461-L482 On Thursday 18 April 2024 at 11:47:16 UTC+1 Vaibhav Ingulkar wrote: > Additionally , I have prepare below config under metric_relable_configs > - action: labelmap > regex: 'tag_(.*)' > replacement: $1 > > It is giving one me new set of all label starting with word '*tag_*' as > added in regex but not converting them to lowercase and removing "*tag_*" > from label name, for ex. *tag_Name* is converted only "N*ame*" > Also existing label *tag_Name* is also remaining as it is .i.e. old label > *tag_Name* and new label *Name* > > So Firstly I want that "*tag_"* should remain as it it in new label and > it should get converted to lower case i.e. for ex. *tag_Budget_Code* to > *tag_budget_code* or *tag_Name* to *tag_name* > Secondly need to remove old label for ex. *tag_Budget_Code* , *tag_Name* , > etc > > On Thursday, April 18, 2024 at 3:46:57 PM UTC+5:30 Vaibhav Ingulkar wrote: > >> Thanks @Brian Kochie >> >> Correct me if I am wrong but I think lower/upper action in relabeling >> works to make "*values*" of labels to lower/upper and not "*keys*" *i.e. >> label name itself wont get convert to lowercase*.
