A logging query has a selector part and a regexp. The regexp matches are highlighted when results return.
This change adds live preview to matches when modifying the regexp in a search field.
- delegate retrieval of match query to datasource
- datasource returns search expressions to be used to highlight a live preview of matches
- logs row now takes preview highlights
- logs row renders preview highlights with dotted line to distinguish from query run matches (solid line)
- fix react-highlight-words version to ensure custom chunk matcher
- custom chunk matcher can now also take incomplete regexps, eg, `(level` without inifinte looping
- perf: debounce of live preview to 500ms
- perf: only top 100 rows get the live preview
- preview is only supported with one query row (multiple rows semantic makes this tricky: regexp for row n should only filter results for query n)
- moved from grid to flexbox
- calculate Explore results only when query transactions change to prevent expensive re-renders
- split up rendering of graph and log data
- render log results in 2 stages
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
- Queries in Explore have been string based
- This PR introduces the use of the DataQuery type to denote all queries handled in Explore
- Within Explore all handling of DataQueries is transparent
- Modifying DataQueries is left to the datasource
- Using `target` as variable names for DataQueries to be consistent with the rest of Grafana
- replace the Graph/Table buttons with toggle control in a wrapper panel
- moved toggle control to left to be close to the label
- removed panel styles from Logs and Graph viewer
- moved loader animation to panel
Explore is about keeping context between datasources if possible. When
changing from metrics to logging, some of the filtering can be kept to
narrow down logging streams relevant to the metrics.
- adds `importQueries` function in language providers
- query import dependent on origin datasource
- implemented prometheus-to-logging import: keeping label selectors
that are common to both datasources
- added types
