* moved datasource related functions to panel sub-class
* expand panel template vars for url
* added keybindings for x -> Explore
* url encoding for explore state
* panel container menu gets new Explore entry (between Edit and Share)
* entry only shows if datasource has `supportsExplore` set to true (set
for Prometheus only for now)
* click on Explore entry changes url to `/explore/state` via location provider
* `state` is a JSON representation of the panel queries
* datasources implement `getExploreState()` how to turn a panel config into explore initial
state
* Explore can parse the state and initialize its query expressions
* ReactContainer now forwards route parameters as props to component
* `pluginlist` and `singlestat` panel subclasses needed to be adapted because
`panel_ctrl` now has the location provider as a property already
The table-panel-wrapper class got removed when clicking on the panel
menu which resulted in extra padding for the .panel-content div. This
fixes that by setting the table-specific css class lower down in the
html.
#11211 removed the unit key ppm in favor of conppm. A change which is not forward compatible.
This commit revert the unit key back to ppm.
Also adds some better error description if trying to use a unit which don't exists.
Fixes#11743
From review feedback:
* s/helper/metadata
* combined positional args to _request into options dict
* metadataRequest reuses _request()
* moved consumption of this.httpMethod into _request, can be overwritten
in options due to spread-after
* When set to `true`, the `silent` option for backend_srv requests
suppresses all event emitters that are triggered when the response is
received.
* Added `helperRequest()` to the Prometheus datasource to support
requests that are not triggered by the user, e.g., for tab completion.
`helperRequest()` sets the `silent` option.
* Migrated all non-timeseries queries of the Prometheus datasource to
use `helperRequest()`.
Fixes#11673
This resolves issue with dash list panel getting scrollbars
attached to incorrect elements. Now the panel content are
rendered correctly and all content are displayed as
expected.
When running queries like 'SHOW [...] CARDINALITY' introduced with
InfluxDB 1.4 there is only a single column 'count'. However, the data
source always assumed 'time' which threw an error because the code
couldn't find a non-time column to display.
This change actually checks this assumption and thereby fixes displaying
the result in a Singlestat in Table mode (closes#11476).
Using a query (POST /render) request instead of GET /metrics/find to better
mimic an actual request for rendering a panel in a dashboard. The POST /render
request will add at least a custom http header which can be problematic when
using direct access mode since it will trigger a CORS prerequest check. By
doing this kind of query when testing the data source possible CORS issues
can be detected there instead of later when trying to use the data source
in a dashboard.
