this is a fix-up PR that cleans up Explore Logging after the recent
restructuring.
- log results need to be merged since query transactions have been
introduced
- logging DS has its own language provider, query field, and start page
(some of them based on prometheus components)
- added loader animation to log viewer
- removed logging logic from prometheus components
- when instantiating a datasource, the datasource service checks if the
plugin module exports Explore components, and if so, attaches them to
the datasource
- Explore component makes all major internal pluggable from a datasource
`exploreComponents` property
- Moved Prometheus query field to promehteus datasource and registered
it as an exported Explore component
- Added new Start page for Explore, also exported from the datasource
- use global range types
- add ErrorBoundary around individual Explore components
- fix table merge on empty results
- fix TimePicker date parsing on ISO dates
- fix TimePicker range string after relative move
Existing querying was grouped together before handed over to the
datasource. This slowed down result display to however long the slowest
query took.
- create one query transaction per result viewer (graph, table, etc.)
and query row
- track latencies for each transaction
- show results as soon as they are being received
- loading indicator on graph and query button to indicate that queries
are still running and that results are incomplete
- properly discard transactions when removing or changing queries
- adds react-table as dependency
- replaces custom table component in Explore
- vendors react-table styles and overrides them (currently in
explore.scss)
* 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
* 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
- 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`.
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
* 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
* adds +/- buttons to query rows in the Explore section
* on Run Query all query expressions are submitted
* `generateQueryKey` and `ensureQueries` are helpers to ensure each
query field has a unique key for react.
