i.e. all the apps.

35b8ffaa17 docs/vmagent.md: clarify -promscrape.suppressDuplicateScrapeTargetErrors command-line flag usage 2020-10-08 19:24:05 +03:00
Aliaksandr Valialkin
0d44e371f3 lib/promscrape: add -promscrape.suppressDuplicateScrapeTargetErrors command-line flag in order to suppress duplicate scrape target errors 
Show also original labels for duplicate targets in error message in order to simplify debugging the issue.

Now `/targets` endpoint accepts optional `show_original_labels=1` query arg, which shows original labels for each target.
This may simplify debugging for target relabeling.
