Add OpenAPI 3.2 specification generation for Prometheus HTTP API ( #17825 )
...
* Add OpenAPI 3.2 specification generation for Prometheus HTTP API
This commit introduces an OpenAPI specification for the Prometheus API.
After testing multiple code-generation servers with built-in APIs, this
implementation uses an independent spec file outside of the critical path.
This spec file is tested with a framework present in this pull request.
The specification helps clients know which parameters they can use and is
served at /api/v1/openapi.yaml. The spec file will evolve with the
Prometheus API and has the same version number.
Downstream projects can tune the APIs presented in the spec file with
configuration options using the IncludePaths setting for path filtering.
In the future, there is room to generate a server from this spec file
(e.g. with interfaces), but this is out of scope for this pull request.
Architecture:
- Core OpenAPI infrastructure (openapi.go): Dynamic spec building,
caching, and thread-safe spec generation
- Schema definitions (openapi_schemas.go): Complete type definitions
for all API request and response types
- Path specifications (openapi_paths.go): Endpoint definitions with
parameters, request bodies, and response schemas
- Examples (openapi_examples.go): Realistic request/response examples
- Helper functions (openapi_helpers.go): Reusable builders for common
OpenAPI structures
Testing:
- Comprehensive test suite with golden file validation
- Test helpers package for API testing infrastructure
- OpenAPI compliance validation utilities
The golden file captures the complete specification for snapshot testing.
Update with: go test -run TestOpenAPIGolden -update-openapi-spec
REVIEWERS: The most important thing to check would be the OpenAPI golden
file (web/api/v1/testdata/openapi_golden.yaml). Test scenarios are important
as they test the actual OpenAPI spec validity.

UI: Fix broken Y axis after graph page reload ( #17869 )
...
* UI: Fix broken Y axis after graph page reload
The new `y_axis_min` setting was always encoded into the URL, even if its value
was `null` (in which case it would be set to an empty string parameter). On the
decoding side, this wasn't taken into account correctly, and we tried to parse
the empty string as a float, causing completely broken graphs showing nothing
after reloading the graph page with such URL parameters.
I'm doing two things now:
* For the future, only encode the Y axis min into the URL if it's set at all,
similar as we do for the `end_input` and `moment_input` fields.
* On the decoding side, accommodate people (at least for now) who already saved
some links with the empty `y_axis_min` parameter by treating an empty string
as `null` instead of a number.

Fix serialization for empty ignoring() in combination with group_x()
...
Currently both the backend and frontend printers/formatters/serializers
incorrectly transform the following expression:
```
up * ignoring() group_left(__name__) node_boot_time_seconds
```
...into:
```
up * node_boot_time_seconds
```
...which yields a different result (including the metric name in the result
vs. no metric name).
We need to keep empty `ignoring()` modifiers if there is a grouping modifier
present.

To reduce main UI clutter, I added a new settings submenu above the chart
itself for the new setting. So far it only has the one new axis setting, but it
could accommodate further settings in the future.
For now I'm only adding a boolean on/off setting to the UI to set the Y axis to
0 or not. However, the underlying stored URL field is already named
y_axis_min={number} and would support other Y axis minima, in case we want to
support custom values in the UI in the future - but then we'd probably also
want to add an axis maximum and possibly other settings.

We already have infinite scrolling for all the rules within a group, but this
adds a second (nested) level of infinite scrolling for the firing alerts within
a rule.
This should further improve the rendering speed for the /alerts page for
Prometheus setups with many firing alerts and when you expand the individual
rule panels that contain those firing alerts.

UI: Speed up alerts/rules/... pages by not rendering collapsed content
...
In contrast to Bootstrap, Mantine's Accordion component didn't remove its
panel contents from the DOM when collapsed, so rendering pages with lots of
collapsed Accordion items was way slower and more resource-intensive in the
new Mantine UI. While I talked to Vitaly from Mantine and he managed to add
unmounting of collapsed panel contents in Mantine 9, this will only be
available next year. So for now, I'm forking over the Accordion component
from Mantine and adding a hacky modification to it that removes contents
for collapsed panels. This fork can be removed after upgrading to Mantine 9
sometime in 2026. I removed all the unnecessary test files and so on and
just kept the core Accordion code files.
This should really help with the following issues:
https://github.com/prometheus/prometheus/issues/17254
https://github.com/prometheus/prometheus/issues/16830
The /alerts and /rules pages should be the most affected since the panels
on those are collapsed by default. The /targets and /service-discovery
pages have expanded panels by default, but I still swapped out the
Accordion implementation for consistency and in case someone collapses a
bunch of panels.

Migrate Mantine v7 -> v8 ( #17402 )
...
I followed the migration guide at https://mantine.dev/guides/7x-to-8x/ to
add back both manual timezone handling in the time input, as well as syntax
highlighting in the config code box.

Without `staleTime: Infinity`, the query data would be immediately marked
stale, and in combination with the `gcTime: 0` setting and a brief unmount
during data loading (via Suspense), the data would have to be reloaded a second
time during/after the first real render.
`gcTime: 0` + `staleTime: Infinity` should give us the desired behavior where
data loaded for a page should be valid forever as long as that page is being
displayed, but always thrown away (and later reloaded) whenever we navigate
away and again to that page.

ui: Allow viewing detailed relabeling steps for each discovered target
...
This adds:
* A `ScrapePoolConfig()` method to the scrape manager that allows getting
the scrape config for a given pool.
* An API endpoint at `/api/v1/targets/relabel_steps` that takes a pool name
and a label set of a target and returns a detailed list of applied
relabeling rules and their output for each step.
* A "show relabeling" link/button for each target on the discovery page
that shows the detailed flow of all relabeling rules (based on the API
response) for that target.
Note that this changes the JSON encoding of the relabeling rule config
struct to output the original snake_case (instead of camelCase) field names,
and before merging, we need to be sure that's ok :) See my comment about
that at https://github.com/prometheus/prometheus/pull/15383#issuecomment-3405591487
