This processor specifically handles Histogram and Timer metrics from the Yammer metrics + * library and converts them to OpenTelemetry gauge metrics that track delta mean values. + * It implements the Yammer {@link MetricProcessor} interface to process metrics and creates + * corresponding OpenTelemetry metrics with proper attributes derived from the metric scope. + * + *

The processor: + *

    + *
  • Converts Yammer Histogram and Timer metrics to OpenTelemetry gauges
    • + *
  • Calculates delta mean values using {@link DeltaHistogram}
    • + *
  • Parses metric scopes to extract attributes for OpenTelemetry metrics
    • + *
  • Maintains a registry of processed metrics for lifecycle management
    • + *
  • Supports metric removal when metrics are no longer needed
    • + *
+ * + *

Supported metric types: + *

    + *
  • {@link Histogram} - Converted to delta mean gauge
    • + *
  • {@link Timer} - Converted to delta mean gauge
    • + *
+ * + *

Unsupported metric types (will throw {@link UnsupportedOperationException}): + *

    + *
  • {@link Counter}
    • + *
  • {@link Gauge}
    • + *
  • {@link Metered}
    • + *
+ * + *

如需自定义配置提供器，可额外设置： + ```properties + log4j.appender.s3_uploader.configProviderClass=com.example.CustomS3LogConfigProvider + ``` + +## 关键配置说明 + +| 配置项 | 说明 | +| ------ | ---- | +| `log.s3.enable` | 是否启用 S3 上传功能。 +| `log.s3.bucket` | 推荐使用 AutoMQ Bucket URI（如 `0@s3://bucket?region=us-east-1&pathStyle=true`）。若为简写桶名，需要额外提供 `log.s3.region` 等字段。 +| `log.s3.cluster.id` / `log.s3.node.id` | 用于构造对象存储路径 `automq/logs/{cluster}/{node}/{hour}/{uuid}`。 +| `log.s3.selector.type` | 选主策略（`static`、`nodeid`、`file`、`kafka` 或自定义）。 +| `log.s3.primary.node` | 搭配 `static` 策略使用，指示当前节点是否为主节点。 +| `log.s3.selector.kafka.*` | Kafka 选主所需的附加配置，如 `bootstrap.servers`、`group.id` 等。 +| `log.s3.active.controller` | **已废弃**，请改用 `log.s3.selector.type=static` + `log.s3.primary.node=true`。 + +上传调度可通过环境变量覆盖： + +- `AUTOMQ_OBSERVABILITY_UPLOAD_INTERVAL`：最大上传间隔（毫秒）。 +- `AUTOMQ_OBSERVABILITY_CLEANUP_INTERVAL`：保留时长（毫秒），旧对象早于该时间会被清理。 + +### 选主策略 + +为避免多个节点同时执行 S3 清理任务，日志上传器内置与 OpenTelemetry 模块一致的选主机制： + +1. **static**：通过 `log.s3.primary.node=true|false` 指定哪个节点为主。 +2. **nodeid**：当 `log.s3.node.id` 等于 `primaryNodeId` 时成为主节点，可在 URL 或属性中设置 `log.s3.selector.primary.node.id`。 +3. **file**：使用共享文件做抢占式选主，配置 `log.s3.selector.file.leaderFile=/shared/leader`、`log.s3.selector.file.leaderTimeoutMs=60000`。 +4. **kafka**：默认策略。所有节点加入单分区主题的同一消费组，持有分区的节点成为主节点。必要配置： + ```properties + log.s3.selector.type=kafka + log.s3.selector.kafka.bootstrap.servers=PLAINTEXT://kafka:9092 + log.s3.selector.kafka.topic=__automq_log_uploader_leader_cluster1 + log.s3.selector.kafka.group.id=automq-log-uploader-cluster1 + ``` + 可通过 `log.s3.selector.kafka.*` 提供安全（SASL/SSL）、超时等高级参数。 +5. **自定义**：实现 `com.automq.log.uploader.selector.LogUploaderNodeSelectorProvider` 并通过 SPI 注册，即可引入自定义选主策略。 + +## 扩展 + +如果应用已有自己的依赖注入/配置方式，可实现 `S3LogConfigProvider` 并在启动时调用： + +```java +import com.automq.log.uploader.S3RollingFileAppender; + +S3RollingFileAppender.setConfigProvider(new CustomConfigProvider()); +``` + +所有 `S3RollingFileAppender` 实例会共用这个 provider。 diff --git
