- currently only the release is used as a fingerprint which produces
caching issues for all lastest master builds
- also add build commit to url fingerprint
- make bra also watch go html template files
- load recording rules from prometheus
- map rule name to rule query
- query hint to detect recording rules in query
- click on hint fix expands rule name to query
* Explore: Query hints for prometheus
- time series are analyzed on response
- hints are shown per query
- some hints have fixes
- fix rendered as link after hint
- click on fix executes the fix action
* Added tests for determineQueryHints()
* Fix index for rate hints in explore
- load all histogrammable metrics on start, based on `{le!=''}` series
query
- select dropdown shows all those metrics as well as histograms in a
special group
- select a metric will write fill the metric in the query box
- if a histogram is chosen, it will write a complete
`histogram_quantile` query
- added new dependency: rc-cascader
- Clear All button to clear all queries and results
- moved result viewer buttons below query rows to make it more clear
that they govern result options
- position was determined by SPACE, but Prometheus selectors can
contain spaces
- added negative lookahead to check if space is outside a selector
- moved braces plugin into PromQueryField since braces are prom specific
- queries are saved to localstorage history array
- one history per datasource type (plugin ID)
- 100 items kept with timestamps
- history suggestions can be pulled up with Ctrl-SPACE
* Explore: facetting for label completion
- unified metric and non-metric label completion
- label keys and values are now fetched fresh for each valid selector
- complete selector means only values are suggested that are supported
by the selector
- properly implemented metric lookup for selectors (until the first
metric was used which breaks when multiple metrics are present)
- typeahead tests now need a valid selection to demark the cursor
* Fix facetting queries for empty selector
* Add click on explore table cell to add filter to query
- move query state from query row to explore container to be able to set
modified queries
- added TS interface for columns in table model
- plumbing from table cell click to datasource
- add modifyQuery to prometheus datasource
- implement addFilter as addLabelToQuery with tests
* Review feedback
- using airbnb style for Cell declaration
- fixed addLabelToQuery for complex label values
* Refactor Explore query field
- extract typeahead field that only contains logic for the typeahead
mechanics
- renamed QueryField to PromQueryField, a wrapper around TypeaheadField
that deals with Prometheus-specific concepts
- PromQueryField creates a promql typeahead by providing the handlers
for producing suggestions, and for applying suggestions
- The `refresher` promise is needed to trigger a render once an async
action in the wrapper returns.
This is prep work for a composable query field to be used by Explore, as
well as editors in datasource plugins.
* Added typeahead handling tests
- extracted context-to-suggestion logic to make it testable
- kept DOM-dependent parts in main onTypeahead funtion
* simplified error handling in explore query field
* Refactor query suggestions
- use monaco's suggestion types (roughly), see
https://github.com/Microsoft/monaco-editor/blob/f6fb545/monaco.d.ts#L4208
- suggest functions and metrics in empty field (ctrl+space)
- copy and expand prometheus function docs from prometheus datasource
(will be migrated back to the datasource in the future)
* Added prop and state types, removed unused cwrp
* Split up suggestion processing for code readability
- using tslib reduces bundle sizes
- add compiler option for easier default imports of CJS modules
- remove double entry of fork-ts-checker-plugin
- speed up hot reload by using exprimental ts-loader API
- new builtin datasource plugin "Logging" (likely going to be renamed)
- plugin implements no panel ctrls yet, only ships datasource
- new models for logging data as first class citizen (aside from table
and time_series model)
- Logs as new view for Explore
- JSON view for development
Testable only against existing logish deployment.
Then test with queries like `{job="..."} regexp`.
- classic dashboard panels inject a dynamic query interval as part of
the query options. Explore did not have that.
- this PR adds the interval calculation to Explore
- interval based on Explore container's width
- ensure min interval if set in datasource
- prometheus datasources passes its own interpolator function to the
template server
- that function relies on incoming values being strings
- some template variables may be non-strings, e.g., `__interval_ms`,
which throws an error
This PR makes this more robust.
Adds a datasource selector to the Explore UI. Only datasource plugins
that have `explore: true` in their `plugin.json` can be selected.
- adds datasource selector (based on react-select) to explore UI
- adds getExploreSources to datasource service
- new `explore` flag in datasource plugins model
- Prometheus plugin enabled explore
- broken since 4d2dd2209
- `*` was previously working as a path matcher, but freezes browser when
used with new cache-busting plugin loader
- changed matcher to be `/*`
* Fix bar width issue in aligned prometheus queries
This was broken because null values were filled in with unaligned times.
* use aligned times for result transformation
* add tests
An earlier version of this fix aligned the times again in the transformer, but
I think it's safe to only deal with aligned times in the response.
* Fixed prometheus heatmap tranformer test
The interval needs to be 1 to prevent step alignment.
Experimental support for react in external plugins
- react
- slate (editor)
- papaparse (csv parsing)
- prismjs (syntax highlighting)
This is needed for new external datasource plugins like Flux
Previous explore restrictions only took permissions into consideration.
* add `exploreEnabled` to global settings
* only bind `x` if enabled
* only show explore in panel menu if enabled
Access is restricted via not showing in the following places:
* hide from sidemenu
* hide from panel header menu
* disable keybinding `x`
Also adds a `roles` property to reactContainer routes that will be
checked if `roles` is set, and on failure redirects to `/`.
* everything imported via systemjs in the path `plugin/` will get a
timestamp appended for cache busting
* timestamp is set once on page load
* plugin css loader gets cache buster too
Motivation:
* too many conditionals for config, better to be explicit
* different priorities: faster build for hot mode
* working SCSS sources for styles in hot mode
The biggest differences:
* removed linter from TS loader in hot (should be editor or precommit
or responsibility)
* simplified styles loading
* hot needs more extensions to resolve
* removed commons chunking for hot
* removed devServer from dev
Reduced HMR time from 8s to 4s on my machine.
* the existing query date alignment shifts the range forward to match
a multiple epoch of the interval, but keeps the range length the same,
the result is that the start date is shifted forward as well, leaving a
gap in the graph (or a zero-line when null-as-zero was set, issue #12024)
* this pr extends the aligned range to cover the original start date as
well
* button to bring a up a duplicate explore area to compare
* side by side rendering of two explore components
* right component has close button
* left component has page title
* style header like other grafana components
* use panel container for graph and same styles for query field
* fix typeahead CSS selector (was created outside of .explore)
* use navbar buttons for +/- of rows
* moved elapsed time under run query button
* fix JS error on multiple timeseries being returned
* fix color for graph lines
* show prometheus query errors
* time selector for explore section
* mostly ported the angular time selector, but left out the timepicker
(3rd-party angular component)
* can be initialised via url parameters (jump from panels to explore)
* refreshing not implemented for now
* moved the forward/backward nav buttons around the time selector
