Justin Burnham	97c7d7ca3c	LogQL: add the `default` sprig template function to logql label/line formatter (#6163 ) * add the `default` sprig template function to logql label/line formatter With the `default` sprig template function, we will be able to make it easier to output a default value if the source string is otherwise empty. Useful for json fields that can be missing, like HTTP headers in a log line that aren't required as in the following: ``` {job="access_log"} \| json \| line_format `{{.http_request_headers_x_forwarded_for \| default "-"}}` ``` Previously this could only be done (that I found) with the much more verbose ``` {{regexReplaceAllLiteral "^$" .http_request_headers_x_forwarded_for "-"}} ``` * update changelog entry * add pr number * enhance docs * Update docs/sources/logql/template_functions.md Co-authored-by: Kaviraj Kanagaraj <kavirajkanagaraj@gmail.com> * Update docs/sources/logql/template_functions.md Co-authored-by: Vladyslav Diachenko <82767850+vlad-diachenko@users.noreply.github.com> Co-authored-by: Kaviraj Kanagaraj <kavirajkanagaraj@gmail.com> Co-authored-by: Owen Diehl <ow.diehl@gmail.com> Co-authored-by: Vladyslav Diachenko <82767850+vlad-diachenko@users.noreply.github.com>	4 years ago

Ed Welch	4bf1648da1	Loki: When processing logs during tailing, don't reuse the query pipeline (#6152 ) * when tailing, don't reuse the query pipeline because it has an unbounded label cache Signed-off-by: Edward Welch <edward.welch@grafana.com> * update changelog Signed-off-by: Edward Welch <edward.welch@grafana.com>	4 years ago
Christian Haudum	ee4ab1b394	Fix certain binary expression queries by optimizing through push down (#6132 ) * Add test cases that fail Instant queries of the following type fail and return an `unimplemented` error: ``` sum(count_over_time({foo="bar"} \| logfmt \| duration > 2s [3s])) / sum(count_over_time({foo="bar"} [3s])) ``` Signed-off-by: Christian Haudum <christian.haudum@gmail.com> * Fix certain binary expressions for instant queries If either the left hand side or the right hand side of a binary expression is a noop, we need to return the original expression so the whole expression is a noop as well, and thus not executed using the downstream engine. Otherwise, a binary expression that has a noop on either side, results in an `unimplemented` error when executed using the downstream engine. Signed-off-by: Christian Haudum <christian.haudum@gmail.com> * Optimize instant vector aggregations with log extraction stage This change optimizes queries that use a vector aggregation without grouping around a range aggregation with a label extraction stage such as `json` or `logfmt`. Since the vector aggregation can be pushed down to the downstream query, the downstream query does not create a massive amount of streams, even though it contains a generic label extraction stage.

Kaviraj Kanagaraj	8b15632dd8	Fix(query-frontend): LokiCodec encode/decode works correctly with label values endpoint (#6084 ) When encode/decode `http.Request` into `querybase.Request` we re-create request.Path. Before this PR, both `/labels/` and `/labels/{name}/values` endpoint was decoding into same URL path `/labels/` before forwarding to the querier. So it always returns label names as response.

Dylan Guedes	cd02d6a478	Add better observability to queryReadiness (#5946 ) * Add two metrics to the IndexGateway. - Add a new `query_readiness_duration_seconds` metric, that reports query readiness duration of a tablemanager/index gateway instance. We should use it later to report performance against the ring mode - Add a new `usersToBeQueryReadyForTotal` metric, that reports number of users involved in the query readiness operation. We should use it later to correlate number of users with the query readiness duration. * Remove `usersToBeQueryReadyForTotal`. - It will report all users always for now, so it isn't too helpful the way it is. * Rename metric help text to not mislead people. * Log queryReadiness duration. * Fix where log message and duration and triggered. * Join users list in a single string. - This is necessary since go-kit doesn't support array type. * Tweak queryReadiness log messages. - As suggested by Ed on https://github.com/grafana/loki/pull/5972#discussion_r859734129 and https://github.com/grafana/loki/pull/5972#discussion_r859736072 * Ensure queryReadinessDuration metric. - It is redundant with a recently added log line. * noop	4 years ago
