otel Metric格式转换

事件能力

列含义见 概览 · 事件能力列说明。

v1 接口	v2 接口	Log	Metric	Span
✓	—	v1	透传未知	透传未知

版本

Stable

版本说明

• 推荐版本：iLogtail v1.8.0 及以上

配置参数

下面是修复后的表格：

参数	类型	是否必选	说明
SourceKey	string	是	原始字段名。
Format	string	是	转换后的格式（枚举类型）。共有三类：protobuf, json, protojson
NoKeyError	bool	否	当没有对应字段时，是否报错。默认值为false

样例

采集/home/test-log目录的simple.log文件，根据指定的配置选项提取日志信息。
