Bryan Boreham	1e3fef6ab0	scraping: limit detail on dropped targets, to save memory (#12647 ) It's possible (quite common on Kubernetes) to have a service discovery return thousands of targets then drop most of them in relabel rules. The main place this data is used is to display in the web UI, where you don't want thousands of lines of display. The new limit is `keep_dropped_targets`, which defaults to 0 for backwards-compatibility. Signed-off-by: Bryan Boreham <bjboreham@gmail.com>	1 year ago

beorn7	2ea8df4734	histogram: Expose #12305 Native histograms without a zero threshold aren't federated properly. This adds a test to prove the specific failure mode, which is that histograms with a zero threshold of zero are federated as classic histograms. The underlying reason is that the protobuf parser identifies a native histogram by detecting a zero bucket or by detecting integer buckets. Therefore, a float histogram with a zero threshold of zero and an unpopulated zero bucket falls through the cracks (no integer buckets, no zero bucket). This commit also addse a test case for the latter. Signed-off-by: beorn7 <beorn@grafana.com>	1 year ago

beorn7	9e500345f3	textparse/scrape: Add option to scrape both classic and native histograms So far, if a target exposes a histogram with both classic and native buckets, a native-histogram enabled Prometheus would ignore the classic buckets. With the new scrape config option `scrape_classic_histograms` set, both buckets will be ingested, creating all the series of a classic histogram in parallel to the native histogram series. For example, a histogram `foo` would create a native histogram series `foo` and classic series called `foo_sum`, `foo_count`, and `foo_bucket`. This feature can be used in a migration strategy from classic to native histograms, where it is desired to have a transition period during which both native and classic histograms are present. Note that two bugs in classic histogram parsing were found and fixed as a byproduct of testing the new feature: 1. Series created from classic _gauge_ histograms didn't get the _sum/_count/_bucket prefix set. 2. Values of classic _float_ histograms weren't parsed properly.

beorn7	5b53aa1108	style: Replace `else if` cascades with `switch` Wiser coders than myself have come to the conclusion that a `switch` statement is almost always superior to a statement that includes any `else if`. The exceptions that I have found in our codebase are just these two: * The `if else` is followed by an additional statement before the next condition (separated by a `;`). * The whole thing is within a `for` loop and `break` statements are used. In this case, using `switch` would require tagging the `for` loop, which probably tips the balance. Why are `switch` statements more readable? For one, fewer curly braces. But more importantly, the conditions all have the same alignment, so the whole thing follows the natural flow of going down a list of conditions. With `else if`, in contrast, all conditions but the first are "hidden" behind `} else if `, harder to spot and (for no good reason) presented differently from the first condition. I'm sure the aforemention wise coders can list even more reasons. In any case, I like it so much that I have found myself recommending it in code reviews. I would like to make it a habit in our code base, without making it a hard requirement that we would test on the CI. But for that, there has to be a role model, so this commit eliminates all `if else` occurrences, unless it is autogenerated code or fits one of the exceptions above.

beorn7	c3c7d44d84	lint: Adjust to the lint warnings raised by current versions of golint-ci We haven't updated golint-ci in our CI yet, but this commit prepares for that. There are a lot of new warnings, and it is mostly because the "revive" linter got updated. I agree with most of the new warnings, mostly around not naming unused function parameters (although it is justified in some cases for documentation purposes – while things like mocks are a good example where not naming the parameter is clearer). I'm pretty upset about the "empty block" warning to include `for` loops. It's such a common pattern to do something in the head of the `for` loop and then have an empty block. There is still an open issue about this: https://github.com/mgechev/revive/issues/810 I have disabled "revive" altogether in files where empty blocks are used excessively, and I have made the effort to add individual `// nolint:revive` where empty blocks are used just once or twice. It's borderline noisy, though, but let's go with it for now. I should mention that none of the "empty block" warnings for `for` loop bodies were legitimate.

beorn7	817a2396cb	Name float values as "floats", not as "values" In the past, every sample value was a float, so it was fine to call a variable holding such a float "value" or "sample". With native histograms, a sample might have a histogram value. And a histogram value is still a value. Calling a float value just "value" or "sample" or "V" is therefore misleading. Over the last few commits, I already renamed many variables, but this cleans up a few more places where the changes are more invasive. Note that we do not to attempt naming in the JSON APIs or in the protobufs. That would be quite a disruption. However, internally, we can call variables as we want, and we should go with the option of avoiding misunderstandings. Signed-off-by: beorn7 <beorn@grafana.com>	2 years ago
