Sometimes log streams dont return any lines for the given range. Would be great to automate the search until some logs are found.
- Allow Explore to drive TimePicker via ref
- Show `Scan` link in Logs when there is no data
- Click on `Scan` sets Explore into scanning state
- While scanning, tell Timepicker to shift left
- TimePicker change triggers new queries with shifted time range
- Remember if query transaction was started via scan
- keep scanning until something was found
- Manual use of timepicker cancels scanning
The existing intro makes it look like you should use `$<varname>` to refer to a variable. That of course is incorrect, and you should use `$varname`. In my experience using the <> marker around variable names should only be used when there isn't something else explicit to set it off. In this case we have `$`. Below, you can see the <> are also not used, because we have the `[[]]` to set it off. The inconsistency is confusing.
- since the DataQuery rewrite, Explore starts by submitting its queries (Explore cant know if the queries are emtpty)
- The datasource intercepts an empty query and returns an empty list of time series, and also no table for the table query.
- The query hinter then received no series to analyse and was not guarding against this.
- This PR adds this guard.
- add `onToggleSeries` to Explore Graph props
- toggling a Logging Graph series from the legend propagates its hidden series to Logs
- Logs translates hidden series alias to LogLevels
- Logs filters out hidden log levels
Logging's query importer drops all labels that are not common to both datasources.
- keep labels if label lookup of logging datasource came back empty
- easier to remove labels than having to add them in the first place
Currently the footer is based on top margins which looks odd on big screen sizes.
Also, the footer shows up on the top of the page on pages take a moment to load (while ng-view is rendering).
- True sticky footer based on flexbox
- Ensure footer stays at bottom while ng-view div does not exist yet
when listing multiple gf-form elements this style is
applied to all elements except the first. By having the
margin on the right side there will always be some margin
between all gf-forms
