Sandeep Sukhani	e625d7f1ca	otel: add support for per tenant configuration for mapping otlp data to loki format (#11143 ) What this PR does / why we need it: In OTEL, we pick select Resource Attributes to identify the streams and store all the other attributes as Structured Metadata, as explained here. The problem however is that the list of Resource Attributes that are picked as Stream labels are hardcoded, and there is no way to drop unwanted data. This PR adds support for configuring how data is mapped from OTEL to Loki format per tenant. It also adds support for dropping unwanted data. We decided to make the config look similar to Prometheus's relabling config to make it familiar. Special notes for your reviewer: Opening a draft PR to get some initial feedback. I will add documentation in a separate PR. Checklist - [x] Tests updated - [x] `CHANGELOG.md` updated	1 year ago
Sandeep Sukhani	6069df8f7d	ingestion: native otlp ingestion support (#10727 ) What this PR does / why we need it: Add support for natively supporting logs ingestion in OTLP format. `/otlp/v1/logs` is the new endpoint where users can push logs in OTLP format. It accepts logs serialized in JSON or proto format. Since OTEL format is very different than what Loki storage model, here is how data in OTEL format will be mapped to Loki data model: * Index labels: The Resource Attributes map quite well to Index labels in Loki since both usually identify the source of the logs. The problem however is that Resource attributes in OTLP can have an unbounded number of values while Loki has a default limit of having up to 30 labels. Since Index labels in Loki can largely drive the kind of querying experience the users are going to have, we have chosen select attributes which would be picked as Index Labels. The ones that are not picked up as Index labels would be stored as Structured Metadata with each log entry. * Timestamp: LogRecord.TimeUnixNano * LogLine: LogRecord.Body holds the body of the log. However, since Loki only supports Log body in string format, we will stringify non-string values using [AsString method from OTEL collector lib](`ab3d6c5b64/pdata/pcommon/value.go (L353)`). * Structured Metadata: Anything which can’t be stored in Index labels and LogLine. Here is a non-exhaustive list of what will be stored in Structured Metadata to give a sense of what it will hold: * Resource Attributes not stored as Index labels is replicated and stored with each log entry. * Everything under InstrumentationScope is replicated and stored with each log entry. * Everything under LogRecord except LogRecord.Body, LogRecord.TimeUnixNano and sometimes LogRecord.ObservedTimestamp. NOTES: * Since Loki does not support `.` or any other special characters other than `_` in label names, we replace all non-supported characters with `_`. * Since Loki only supports string in values of Index Labels and Structured Metadata, all the complex types are converted as follows: * Map would be flattened into label keys using `_` as separator, same as how we do it in [json parser in LogQL](https://grafana.com/docs/loki/latest/query/log_queries/#json). * Everything else is stringified using [AsString method from OTEL collector lib](`ab3d6c5b64/pdata/pcommon/value.go (L353)`) Special notes for your reviewer: I will open follow-up PRs for: * Documentation * Make blessed attributes list configurable per tenant.

Christian Haudum	6d7422aabf	Assert that push values tuples consist of string values (#5685 ) * Assert that push values tuples consist of string values This fixes a bug in the parsing of push requests that could allowed users sending non-string "log lines" from clients, such as full JSON objects. The values were interpreted as strings, even though they weren't, leading to unexpected log line transformation because the request did not fail.

Dylan Guedes	ab10bc69d7	Loki: Change how push API checks for contentType (#4443 ) * Change how push API checks for contentType - Currently, the ContentType is expected to be exactly "application/json". That's a problem because although a "application/json; charset=utf-8" is considered a valid JSON content type, it will be seen as an error. * Use mime.ParseMediaType to parse contentType. - mime.ParseMediaType is more reliable than strings.Contains because if a wrong contentType (such as "application/jsonnn") is given, we still accept it - mime.ParseMediaType has support for contentType parameters. This way, valid contentTypes such as "application/json; charset=utf-8" will not be rejected * Add changelog entry. * Change body in test to avoid lint issues. - Without this change, the lint fails because gzipString would be called with always the same input. Full error: ``` `gzipString` - `source` always receives ``{"streams": [{ "stream": { "foo": "bar2" }, "values": [ [ "1570818238000000000", "fizzbuzz" ] ] }]}` ("{\"streams\": [{ \"stream\": { \"foo\": \"bar2\" }, \"values\": [ [ ...) ` (unparam) ```	4 years ago
