* Prometheus: user metrics metadata to inform query hints
- no longer analyse datapoints
- either use metrics metadata to determine metrics type or use metric
name suffix
- removed testcases based on datapoints
* Added hint certainty and tests
* Prometheus: Disable suggestions at beginning of value
- fixed comparison operator regex
- no longer suggest anything at beginning of label value
* Detect cursor in front of label values
* Loki: fix filter expression suggestions
- dont suggest term completion items in filter expression
- allow at least one character before suggesting term items
- keep logql expression when switching between Metrics/Logs mode
- show only history by default in completion items
* Clear results when changing mode
- `unless`, `or` and `and` are binary operators
- if they appear in a query the query was broken up so the suggestor
only works on the current term
- this change fixes the splitter logic to make sure those keywords are
not inside a word
- prometheus explore editor introduced new styles for the hint display
- when multiple rows are rendered the hints are covered because they are
forced to have 0 height
- this change removes the 0-height
* Editor: Ignore closing brace when it was added by editor
- brace completion gets annoying if the user still types closing brace
- this change marks automatically added closing braces and when the user
types a closing brace at that position, it will be overridden instead of
added
* Fix label suggestions
* Correct brace behavior, but broken completion
* Rewrite auto-match detection with annotations
* Prometheus: Display HELP and TYPE of metrics if available
- Prometheus recently added a metadata API around HELP and TYPE of
metrics
- request metadata when datasource instance is created
- use metadata to show help and type in typeahead suggestions and in
metrics selector as tooltip
* Fix types
* Logs: Optional logs label column
- reintroduces label column that was removed when log details were
introduced
- added to explore and also as a new option to logs panel
- explore column settings now stored in localstorage
- labels are rendered with font size xs
- labels that start with `_` or are called `level` or `filename` are not
displayed
- removed click handlers and moved remaining `LogLabel` logic into `LogLabels`
* Added prop to satisfy interface
* Review feedback
* removed comment
* Changed label of label column switch
* Prometheus: disable dynamic label lookup on big datasources
- when a prometheus datasource has more than 10000 metrics, label lookup
for the query field is disabled
- installations of that size have slow typehead lookup times and make
the editor sluggish
* Raise dynamic lookup threshold to 10000 metrics
* Run start tasks again
- since the API update, the URL fallback was working, but the response
format also needed adapting: `data` (v1) vs `values` (pre-v1)
- this change looks for either data or values in the response for test
and metadata requests
* Loki: Fix query error for step parameter
- Loki does not fully support float steps like prometheus and returns a
query error
- this change makes sure that the step parameter is rounded to an
integer
* Added test and comments
* Docker blocks: Add loki blocks for loki releases
- Loki did major API changes between 0.3 and 0.4
- Adding blocks to simplify Grafana datasource testing for different
versions
- keeing `loki` block pointing at loki master
- Run all versions in parallel:
```
./create_docker_compose.sh loki0.3 loki0.4 loki
```
- all versions have different hostnames and ports internally
- datasource url depends on version so you can set them up as separate
datasources:
- master: http://localhost:3100/
- 0.3.0: http://localhost:3103/
- 0.4.0: http://localhost:3104/
* Add loki minor version datasources
* Elasticsearch: Support rendering in logs panel
- add "Logs" metric query type so panels can inform the datasource that
the query is a logs query
- datasource modifies target when metric query type `logs` is detected
- then existing log result processeing paths are followed
* Fix failing test, number of agg types changed
As discussed in a UX feedback session, it's annoying that queries are
automatically executed in Explore. This change adds props to override
the blur behavior.
- add `onBlur` to Explore query field props
- Explore's query row will pass down an empty function for onBlur to the
query fields
- pass onBlur through to the QueryField component for Loki and
Prometheus
- add test to QueryField to make sure if onBlur is specified, the
onRunQuery is not executed
* Explore: Remove datasource testing on selector
- datasource testing gets in the way of fast query iteration: switching
between datasources can take seconds
- it should not be explore's duty to test datasources in the first place
- removed the concept of datasourceError in Explore, should not be its
concern
- datasource erorrs will express themselves in query errors just fine
- connection errors are still bubbled up
- removed reconnection logic from explore, should not be its concern
- missing labels in loki are still "visible" via an empty label selector
- Loki and Prometheus treated connection errors differently than other
datasources, making sure to pass through the original error message
* Show datasource error in query field for prom/loki/influx
* Removed connection test case, fixed disabled state
* Graph: constant series as override
- ability to define a series override that takes the first value of a
timeseries and produces constant series from it.
* Moved constant series override logic to grafana-ui
* Added docs for instant queries and constant series override
* Loki: Updated cheat sheet with new filter syntax
- updated cheat sheet with new filter syntax
- added user-specific examples from the user's label set
- added link to LogQL docs
- separated styles for examples (clickable) and expressions
* Review feedback
- upgraded rc-cascader (did not fix the alignment issue)
- Safari seems to default to middle alignment, added override to explore
styles
- added empty expand icon property to satisfy API after upgrade
* Build: Removed typescript checking from dev bundler
- when switching branches and trying out features, TS checking and bundling are eating up a lot
of CPU
- most of us are using an editor with typechecking support
- this commit removes type checking from the dev bundler
- we still have type checking enabled as a precommit hook and as part of
the prod bundler
* Adds new npm script: start:noTsCheck
* WIP prometheus editor same in panel
* Dont use panel in plugin editors
* prettiered modified files
* Fix step in external link
* Prevent exiting edit mode when slate suggestions are shown
* Blur behavior and $__interval variable
* Remove unused query controller
* Basic render test
* Chore: Fixes blacklisted import
* Refactor: Adds correct start and end time
* (feat/explore): Support for new LogQL filtering syntax
Loki is adding syntax to support chained filtering.
This PR adapts Grafana to support this.
- Send only `query` parameter in loki request
- Automatically wrap search text in simple syntax, e.g., `{} foo` is
sent as `{} |~ "foo"`.
* Adapted to regexp parameter staying on in Loki
* Dont wrap single regexp in new filter syntax
* Fix datasource test
* Fallback regexp parameter for legacy queries
* Fix search highlighting
* Make highlighting work for filter chains
* Fix datasource test
* fix(explore): Prevent double querying for Prometheus and Loki
- queries were triggered twice because two Enter handlers existed
- removed runner plugin from Loki and Prom query fields (runner plugin
is still being used in azure)
Part of #16995
* Set loki's mtrics capability to false
Loki is not a metrics store. Explore was using the `metrics` field in
the plugin definition to issue a second query run. But Loki shows only
one result viewer.
Fixes#16995
- future alignment cause issues with rate charts and the display of last
values
- this change modifies the alignment to use the last available aligned
end date and no longer possibly requests data from the future
Fixes#15635
Importing ansicolor from node_modules or vendored as is failed because
there is no ES5 transpiler configured for ES6 libs.
- remove ansicolor from package.json
- add ansicolor to public/vendor/ansicolor and port to typescript
- adapt all ansicolor imports
- add `public/vendor` as a path to be considered by ts compiler
- click on the name label in a prometheus table was disabled
- it was disabled because every query used to have a metric which is no
longer true
- this change enables it
- lines for graphs from different query rows end up in different
transactions
- within each transaction the color distribution resets leading to color
overlap
- this change takes existing transaction colors into account
- after mounting with an initial value, the onChange of a query field is triggered
- even though the slate documents are not the same, their text values are identical, hence the change propagation is useless
- added check to propagate text change only when text has actually changed
- The "missing" action was triggered unless the number of datasource >1 🤦
- Made datasource preselection more robust in case the requested datasource is already gone
- moved ActionTypes to `./state/actionTypes`
- renamed click-related actions
- added comments to actions and state types
- prefixed Explore actions with `explore/`
- fixed query override issue when row was added
- since e731c248d7 step calculation for
annotation queries was broken
- this change puts the interval in the correct parameter so it gets
considered in `createQuery`
- added tests
- tried split selector and search for a week, and it did not feel natural
- keeping some of the original modifications in QueryField from splitting PR
- adapted CheatSheet and placeholder text
- added new label selector state: No labels found
- Loki queries must contain a limit
- this change makes this limit configurable in the datasource
- keep default at 1000, add tooltip on why inc/dec makes sense
- added tests
- changed log parser API to be more semantic: getting fields, getting values
- regexps become an implementation detail of parser and are no longer part of the API
- improved JSON parser to not be tripped by nested quotation marks
- improved JSON parser to support numbers
- added more tests
- add second query field to logging datasource query component
- second field manages search term, first field manages stream selectors
- improved logging cheat sheet to get started
- react profiler seems to evaluate all props of all components down the tree
- this becomes slow when 1000 rows are passed to 1000 rows and their labels
- use getter function instead to ask for rows on demand
Lazily parse lines and display stats for field when clicked on.
- log line parsers for JSON (basic), and logfmt
- delayed parsing in case user moves to other line
- reuse label stats for field stats
