Adds ready probe (#874) 
* adds leading forward slash check for scrapeURL path
https://github.com/VictoriaMetrics/VictoriaMetrics/issues/835

* adds ready probe for scrape config initialization,
it should prevent metrics loss during vmagent rolling update,
/ready api will return 425 http code, if some scrape config still waits for initialization.

* updates docs

* Update app/vmagent/README.md

* renames var

* Update app/vmagent/README.md

84227ea2fc app/{vminsert,vmagent}: take into account all the inserted rows before relabeling in vm_rows_inserted_total and vmagent_rows_inserted_total metrics 2020-10-09 13:29:51 +03:00

71ea4935de 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.
