If the number is bounded, say no more than 4 dashes, then you can just have
4 rewriting rules, each of which rewrites one. Just repeat the rule N
times:
- source_labels: [label1]
regex: '(.*)-(.*)'
replacement: '${1}_${2}'
target_label: label1
- source_labels: [label1]
regex: '(.*)-(.*)'
replacement: '${1}_${2}'
target_label: label1
- source_labels: [label1]
regex: '(.*)-(.*)'
replacement: '${1}_${2}'
target_label: label1
- source_labels: [label1]
regex: '(.*)-(.*)'
replacement: '${1}_${2}'
target_label: label1
But I ask the question, why?
If it's your own exporter - then fix the exporter.
If it's someone else's exporter - then use the labels as they are.
If you still need it - then write a scraping proxy (where you scrape the
proxy, the proxy scrapes the target, and the proxy modifies the labels in
whatever way you like)
