Aliaksandr Valialkin ac5528cb46 lib/promscrape: properly add exported_ prefix to labels, which clash with target labels if honor_labels: true option isn't set. ... The issue was in the `labels := dst[offset:]` line in the beginning of appendExtraLabels() function. The `dst` may be re-allocated when adding extra labels to it. In this case the addition of `exported_` prefix to labels inside `labels` slice become invisible in the returned `dst` labels. While at it, properly handle some corner cases: - Add additional `exported_` prefix to clashing metric labels with already existing `exported_` prefix. - Store scraped metric names in `exported___name__` label if scrape target contains `__name__` label. Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/3278 Thanks to @jplanckeel for the initial attempt to fix this issue at https://github.com/VictoriaMetrics/VictoriaMetrics/pull/3281		2022-10-28 22:15:31 +03:00
