Ed Welch	4c88be0ef2	chore: update loki modules for 3.0 release (#12433) ... Signed-off-by: Edward Welch <edward.welch@grafana.com>	2 years ago
Salva Corts	52a3f16039	Flag categorize labels on streams response (#10419) ... We recently introduced support for ingesting and querying structured metadata in Loki. This adds a new dimension to Loki's labels since now we arguably have three categories of labels: _stream_, _structured metadata_, and _parsed_ labels. Depending on the origin of the labels, they should be used in LogQL expressions differently to achieve optimal performance. _stream_ labels should be added to stream matchers, _structured metadata_ labels should be used in a filter expression before any parsing expression, and _parsed_ labels should be placed after the parser expression extracting them. The Grafana UI has a hard time dealing with this same problem. Before https://github.com/grafana/grafana/pull/73955, the filtering functionality in Grafana was broken since it was not able to distinguish between _stream_ and _structured metadata_ labels. Also, as soon as a parser expression was added to the query, filters added by Grafana would be appended to the end of the query regardless of the label category. The PR above implements a workaround for this problem but needs a better API on Loki's end to mitigate all corner cases. Loki currently returns the following JSON for log queries: ```json ... { "stream": { "cluster": "us-central", "container": "query-frontend", "namespace": "loki", "level": "info", "traceID": "68810cf0c94bfcca" }, "values": [ [ "1693996529000222496", "1693996529000222496 aaaaaaaaa.....\n" ], ... }, { "stream": { "cluster": "us-central", "container": "query-frontend", "namespace": "loki", "level": "debug", "traceID": "a7116cj54c4bjz8s" }, "values": [ [ "1693996529000222497", "1693996529000222497 bbbbbbbbb.....\n" ], ... }, ... ``` As can be seen, there is no way we can distinguish the category of each label. This PR introduces a new flag `X-Loki-Response-Encoding-Flags: categorize-labels` that makes Loki return categorized labels as follows: ```json ... { "stream": { "cluster": "us-central", "container": "query-frontend", "namespace": "loki", }, "values": [ [ "1693996529000222496", "1693996529000222496 aaaaaaaaa.....\n", { "structuredMetadata": { "traceID": "68810cf0c94bfcca" }, "parsed": { "level": "info" } } ], [ "1693996529000222497", "1693996529000222497 bbbbbbbbb.....\n", { "structuredMetadata": { "traceID": "a7116cj54c4bjz8s" }, "parsed": { "level": "debug" } } ], ... }, ... ``` Note that this PR only supports log queries, not metric queries. From a UX perspective, being able to categorize labels in metric queries doesn't have any benefit yet. Having said that, supporting this for metric queries would require some minor refactoring on top of what has been implemented here. If we decide to do that, I think we should do it on a separate PR to avoid making this PR even larger. I also decided to leave out support for Tail queries to avoid making this PR even larger. Once this one gets merged, we can work to support tailing. --- **Note to reviewers** This PR is huge since we need to forward categorized all over the codebase (from parsing logs all the way to marshaling), fortunately, many of the changes come from updating tests and refactoring iterators. Tested out in a dev cell with query `'{stream="stdout"} | label_format new="text"`. - Without the new flag: ``` $ http http://127.0.0.1:3100/loki/api/v1/query_range\?direction\=BACKWARD\&end\=1693996529322486000\&limit\=30\&query\=%7Bstream%3D%22stdout%22%7D+%7C+label_format+new%3D%22text%22\&start\=1693992929322486000 X-Scope-Orgid:REDACTED { "data": { "result": [ { "stream": { "new": "text", "pod": "loki-canary-986bd6f4b-xqmb7", "stream": "stdout" }, "values": [ [ "1693996529000222496", "1693996529000222496 pppppppppppp...\n" ], [ "1693996528499160852", "1693996528499160852 pppppppppppp...\n" ], ... ``` - With the new flag ``` $ http http://127.0.0.1:3100/loki/api/v1/query_range\?direction\=BACKWARD\&end\=1693996529322486000\&limit\=30\&query\=%7Bstream%3D%22stdout%22%7D+%7C+label_format+new%3D%22text%22\&start\=1693992929322486000 X-Scope-Orgid:REDACTED X-Loki-Response-Encoding-Flags:categorize-labels { "data": { "encodingFlags": [ "categorize-labels" ], "result": [ { "stream": { "pod": "loki-canary-986bd6f4b-xqmb7", "stream": "stdout" }, "values": [ [ "1693996529000222496", "1693996529000222496 pppppppppppp...\n", { "parsed": { "new": "text" } } ], [ "1693996528499160852", "1693996528499160852 pppppppppppp...\n", { "parsed": { "new": "text" } } ], ... ```	2 years ago
Salva Corts	48660d5cd5	Fix bugs in non-indexed-labels (#10142) ... **What this PR does / why we need it**: This PR fixes some bugs discovered while setting the default chunk format yo _V4_ and the default head format to _unordered with non-indexed labels_. Note that this PR doesn't change the defaults, but fixes some bugs that would prevent us from changing them in the future. The bugs it fixes are: - Index out-of-range panic when symbols' labels are empty and we do a Lookup. **Test added**. - When applying retention, new chunks wouldn't contain non-indexed labels (caused by https://github.com/grafana/loki/pull/10090). **Test added**. - New chunks would fail to serialize non-indexed labels when applying retention because the head format would be the [dummy one (ordered)][1] [(used here via `c.headFmt`)][2]. **Cannot test unless we change the default chunk/head format** but tested manually. **Checklist** - [ ] Reviewed the [`CONTRIBUTING.md`](https://github.com/grafana/loki/blob/main/CONTRIBUTING.md) guide (**required**) - [ ] Documentation added - [ ] Tests updated - [ ] `CHANGELOG.md` updated - [ ] If the change is worth mentioning in the release notes, add `add-to-release-notes` label - [ ] Changes that require user attention or interaction to upgrade are documented in `docs/sources/setup/upgrade/_index.md` - [ ] For Helm chart changes bump the Helm chart version in `production/helm/loki/Chart.yaml` and update `production/helm/loki/CHANGELOG.md` and `production/helm/loki/README.md`.
