### Describe Your Changes
- datadog /api/v2/logs api supports message field in json format, which
is not documented and is used by serverless extension. This PR allows
message field to be both string and object type. Also added support of
not documented timestamp field
- added `-datadog.streamFields` and `-datadog.ignoreFields` flags to
configure default stream fields for datadog logs, where there's no
alternative option to pass extra headers and query args
- added ingest `max` and `min` values of data, which are ingested using
`datadogsketches` API, which is also actively used by serverless
extensions
- use default `.` separator instead of `_` for sketches metric names
until metrics are not sanitized
Previously vl_rows_ingested_total metric was tracked individually per each supported data ingestion protocols.
It is better from maintainability PoV tracking this metric consistently in a single place - at logMessageProcessor.AddRow() function
in the same way as vl_bytes_ingested_total metric is tracked.
This is a follow-up for 50bfa689c9
This metric tracks an approximate amounts of bytes processed when parsing the ingested logs.
The metric is exposed individually per every supported data ingestion protocol. The protocol name
is exposed via "type" label in order to be consistent with vl_rows_ingested_total metric.
Thanks to @tenmozes for the initial idea and implementation at https://github.com/VictoriaMetrics/VictoriaMetrics/pull/7682
While at it, remove the unneeded "format" label from vl_rows_ingested_total metric.
The "type" label must be enough for encoding the data ingestion format.
This commit adds the following changes:
- Added support to push datadog logs with examples of how to ingest data
using Vector and Fluentbit
- Updated VictoriaLogs examples directory structure to have single
container image for victorialogs, agent (fluentbit, vector, etc) but
multiple configurations for different protocols
