David 25e1238022 Logs: Fix total bytes process calculation (#24691)
- log stats for Loki are per query
- this change tracks the query stats by refId, preventing the summing of
    the same stats across multiple series of the same response.

David 01bbcf4eea Editor: New line on Enter, run query on Shift+Enter (#24654)
* Editor: New line on Enter, run query on Shift+Enter

- default Enter behavior on query editor fields should be a new line
- special behavior should require a special key: running a query is now
done on Shift-Enter
- Plugins order had to be changed because when typeahead is shown, Enter
is accepting the suggestion

* Run with ctrl-enter, hint in query placeholder

* Fix Kusto field behavior for Enter

* Fix Kusto field behavior for default suggestion
2020-05-14 15:13:45 +02:00
David 34f61934a1 Editor: No default suggestion selected (#24479)
* QueryField: No default suggestion selected

It's been a long-standing issue that careless typing lead to unwanted
tab completion insertions. With this change the completion item list no
longer selects the first item by default. The user has to actively click
ArrowDown to select the first one.

* Added type export

* Remove width limit of typeahead list

Davidandgotjosh 9208c8efd7 Prometheus: Add metadata for summary metrics (#24201)
* Prometheus: Add metadata for summary metrics

- summary metrics don't have metadata available from the metadata API,
so Grafana can help and just add it
- given a summary metric `foo`, we add metadata info for `foo_sum` and
`foo_count`
- with tests

* Update public/app/plugins/datasource/prometheus/language_utils.ts

David 314d442dc7 Loki: Fix query stats display in Explore (#24348)
- the stats label changed in the original PR, so the custom key did no
longer work, this change fixes it and the total bytes processed show up
in the explore logs meta data

David 9420873e6c Loki: Show loki datasource stats in panel inspector (#24190)
* Loki: Show loki datasource stats in panel inspector

- puts the loki query result stats into the query results meta stat API
of Grafana, this allows the display of all backend loki stats in the
panel inspector in the dashboards
- added a hack to also display one of those values in Explore as a meta
label using the dataframe meta `custom` mechanims to point to a single
stat entry for each series which is then added together to show total
bytes processed across all query row results (this should be changed for
7.1 to make full use of the panel inspector in Explore)

* Fix test

* nicer stats labels for loki stats with units

David 649fa6789e Prometheus: Fix term completion that contain keywords (#21295)
- `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

David d0ba644355 Promtheus: Fix hint and error display for query rows (#21242)
- prometheus explore editor introduced new styles for the hint display

- this change removes the 0-height

David 6ac53a1312 Editor: Ignore closing brace when it was added by editor (#21172)
* 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

David 13073fa6ba Prometheus: Display HELP and TYPE of metrics if available (#21124)
* Prometheus: Display HELP and TYPE of metrics if available

- use metadata to show help and type in typeahead suggestions and in
metrics selector as tooltip

* Fix types

David e7ae220cde Logs: Optional logs label column (#21025)
* 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

David 1a2dad9d0c Prometheus: disable dynamic label lookup on big datasources (#20936)
* 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
2019-12-09 17:02:17 +01:00
David 7665dcc867 Loki: Fix datasource config page test run (#20971)
- 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

integer

* Added test and comments

David c941718a5f Docker blocks: Add loki blocks for loki releases (#20172)
* 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

David 9507eda9d1 QueryField: Prevent query runs on blur in Explore (#20180)
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
2019-11-06 15:08:30 +00:00
David 781cff07af Explore: Remove datasource testing on selector (#19910)
* 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

David 89abc77b22 Build: Optional skipping of typescript checking in dev bundler (#18772)

- 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

David 927e1cbd27 (feat/explore): Support for new LogQL filtering syntax (#16674)
* (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

David bf5b60f74a fix(explore): Prevent double querying for Prometheus and Loki (#17004)
* 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.
