Other submodules only need to depend on this module and configure it simply to synchronize logs to object storage. Core components: + +- `com.automq.log.uploader.S3RollingFileAppender`: Extends `RollingFileAppender`, pushes log events to the uploader while writing to local files. +- `com.automq.log.uploader.LogUploader`: Asynchronously buffers, compresses, and uploads logs; supports configuration switches and periodic cleanup. +- `com.automq.log.uploader.S3LogConfig`/`S3LogConfigProvider`: Abstracts the configuration required for uploading. The default implementation `PropertiesS3LogConfigProvider` reads from `automq-log.properties`. + +## Quick Integration + +1. Add dependency in your module's `build.gradle`: + ```groovy + implementation project(':automq-log-uploader') + ``` +2. Create `automq-log.properties` in the resources directory (or customize `S3LogConfigProvider`): + ```properties + log.s3.enable=true + log.s3.bucket=0@s3://your-log-bucket?region=us-east-1 + log.s3.cluster.id=my-cluster + log.s3.node.id=1 + log.s3.selector.type=kafka + log.s3.selector.kafka.bootstrap.servers=PLAINTEXT://kafka:9092 + log.s3.selector.kafka.group.id=automq-log-uploader-my-cluster + ``` +3. Reference the Appender in `log4j.properties`: + ```properties + log4j.appender.s3_uploader=com.automq.log.uploader.S3RollingFileAppender + log4j.appender.s3_uploader.File=logs/server.log + log4j.appender.s3_uploader.MaxFileSize=100MB + log4j.appender.s3_uploader.MaxBackupIndex=10 + log4j.appender.s3_uploader.layout=org.apache.log4j.PatternLayout + log4j.appender.s3_uploader.layout.ConversionPattern=[%d] %p %m (%c)%n + ``` + If you need to customize the configuration provider, you can set: + ```properties + log4j.appender.s3_uploader.configProviderClass=com.example.CustomS3LogConfigProvider + ``` + +## Key Configuration Description + +| Configuration Item | Description | +| ------ | ---- | +| `log.s3.enable` | Whether to enable S3 upload function. +| `log.s3.bucket` | It is recommended to use AutoMQ Bucket URI (e.g. `0@s3://bucket?region=us-east-1&pathStyle=true`). If using a shorthand bucket name, additional fields such as `log.s3.region` need to be provided. +| `log.s3.cluster.id` / `log.s3.node.id` | Used to construct the object storage path `automq/logs/{cluster}/{node}/{hour}/{uuid}`. +| `log.s3.selector.type` | Leader election strategy (`static`, `nodeid`, `file`, `kafka`, or custom). +| `log.s3.primary.node` | Used with `static` strategy to indicate whether the current node is the primary node. +| `log.s3.selector.kafka.*` | Additional configuration required for Kafka leader election, such as `bootstrap.servers`, `group.id`, etc. +| `log.s3.active.controller` | **Deprecated**, please use `log.s3.selector.type=static` + `log.s3.primary.node=true`. + +The upload schedule can be overridden by environment variables: + +- `AUTOMQ_OBSERVABILITY_UPLOAD_INTERVAL`: Maximum upload interval (milliseconds). +- `AUTOMQ_OBSERVABILITY_CLEANUP_INTERVAL`: Retention period (milliseconds), old objects earlier than this time will be cleaned up. + +### Leader Election Strategies + +To avoid multiple nodes executing S3 cleanup tasks simultaneously, the log uploader has a built-in leader election mechanism consistent with the OpenTelemetry module: + +1. **static**: Specify which node is the leader using `log.s3.primary.node=true|false`. +2. **nodeid**: Becomes the leader node when `log.s3.node.id` equals `primaryNodeId`, which can be set in the URL or properties with `log.s3.selector.primary.node.id`. +3. **file**: Uses a shared file for preemptive leader election, configure `log.s3.selector.file.leaderFile=/shared/leader`, `log.s3.selector.file.leaderTimeoutMs=60000`. +4. **kafka**: Default strategy. All nodes join the same consumer group of a single-partition topic, the node holding the partition becomes the leader. Necessary configuration: + ```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 + ``` + Advanced parameters such as security (SASL/SSL), timeout, etc. can be provided through `log.s3.selector.kafka.*`. +5. **custom**: Implement `com.automq.log.uploader.selector.LogUploaderNodeSelectorProvider` and register it through SPI to introduce a custom leader election strategy. + +## Extension + +If the application already has its own dependency injection/configuration method, you can implement `S3LogConfigProvider` and call it at startup: + +```java +import com.automq.log.uploader.S3RollingFileAppender; + +S3RollingFileAppender.setConfigProvider(new CustomConfigProvider()); +``` + +All `S3RollingFileAppender` instances will share this provider. diff --git a/automq-log-uploader/build.gradle b/automq-log-uploader/build.gradle new file mode 100644 index 0000000000..72dd261d03 --- /dev/null +++ b/automq-log-uploader/build.gradle @@ -0,0 +1,19 @@ +plugins { + id 'java-library' +} + +repositories { + mavenCentral() +} + +dependencies { + api project(':s3stream') + + implementation project(':clients') + implementation libs.reload4j + implementation libs.slf4jApi + implementation libs.slf4jBridge + implementation libs.nettyBuffer + implementation libs.guava + implementation libs.commonLang +} diff --git a/automq-log-uploader/src/main/java/com/automq/log/uploader/DefaultS3LogConfig.java b/automq-log-uploader/src/main/java/com/automq/log/uploader/DefaultS3LogConfig.java new file mode 100644 index 0000000000..d0eb40b1df --- /dev/null +++ b/automq-log-uploader/src/main/java/com/automq/log/uploader/DefaultS3LogConfig.java @@ -0,0 +1,201 @@ +/* + * Copyright 2025, AutoMQ HK Limited. + * + * Licensed to the Apache Software Foundation (ASF) under one or more + * contributor license agreements.

AutoMQ Telemetry Configuration + +Ensure the AutoMQ telemetry is properly configured. Add these properties to your application configuration: + +```properties +# Telemetry export configuration +automq.telemetry.exporter.uri=prometheus://localhost:9090 +# or for OTLP: automq.telemetry.exporter.uri=otlp://localhost:4317 + +# Service identification +service.name=kafka-connect +service.instance.id=connect-worker-1 + +# Export settings +automq.telemetry.exporter.interval.ms=30000 +automq.telemetry.metric.cardinality.limit=10000 +``` + +## S3 Log Upload + +Kafka Connect bundles the AutoMQ log uploader so that worker logs can be streamed to S3 together with in-cluster cleanup. The uploader reuses the same leader election mechanism as the metrics, using Kafka by default, and requires no additional configuration. + +### Worker Configuration + +Add the following properties to your worker configuration (ConfigMap, properties file, etc.): + +```properties +# Enable S3 log upload +log.s3.enable=true +log.s3.bucket=0@s3://your-log-bucket?region=us-east-1 + +# Optional overrides (defaults shown) +log.s3.selector.type=kafka +log.s3.selector.kafka.bootstrap.servers=${bootstrap.servers} +log.s3.selector.kafka.topic=__automq_connect_log_leader_${group.id} +log.s3.selector.kafka.group.id=automq-log-uploader-${group.id} +# Provide credentials if the bucket URI does not embed them +# log.s3.access.key=... +# log.s3.secret.key=... +``` + +`log.s3.node.id` defaults to a hash of the pod hostname if not provided, ensuring objects are partitioned per worker. For `static` or `nodeid` leader election, you can explicitly set: + +```properties +log.s3.selector.type=static +log.s3.primary.node=true # Set true only on the primary node, false on others +``` + +### Log4j Integration + +`config/connect-log4j.properties` has switched `connectAppender` to `com.automq.log.uploader.S3RollingFileAppender` and specifies `org.apache.kafka.connect.automq.ConnectS3LogConfigProvider` as the config provider.

The S3 Metrics Exporter provides several built-in node selection strategies through the `UploaderNodeSelector` interface: + +1. **Static Selection** (`static`) + + Uses a static configuration to determine which node uploads metrics. + + ```properties + automq.telemetry.s3.selector.type=static + automq.telemetry.s3.primary.node=true + ``` + +2. **Node ID Based Selection** (`nodeid`) + + Selects the node with a specific node ID as the primary uploader. + + ```properties + automq.telemetry.s3.selector.type=nodeid + # Additional parameters + # primaryNodeId=1 # Can be specified in URI query parameters if needed + ``` + +3. **File-Based Leader Election** (`file`) + + Uses a file on a shared filesystem to implement simple leader election. + + ```properties + automq.telemetry.s3.selector.type=file + # Additional parameters (can be specified in URI query parameters) + # leaderFile=/path/to/leader-file + # leaderTimeoutMs=60000 + ``` + +4. **Kafka-based Leader Election** (`kafka`) + + Leverages Kafka consumer group partition assignment. All nodes join the same consumer group and subscribe to a single-partition topic; the node that holds the partition becomes the primary uploader while others stay on standby. + + ```properties + automq.telemetry.s3.selector.type=kafka + # Recommended to configure using the automq.telemetry.s3.selector.kafka. prefix + automq.telemetry.s3.selector.kafka.bootstrap.servers=PLAINTEXT://kafka:9092 + automq.telemetry.s3.selector.kafka.topic=__automq_telemetry_s3_leader_connect + automq.telemetry.s3.selector.kafka.group.id=automq-telemetry-s3-connect + automq.telemetry.s3.selector.kafka.topic.replication.factor=3 + automq.telemetry.s3.selector.kafka.security.protocol=SASL_PLAINTEXT + automq.telemetry.s3.selector.kafka.sasl.mechanism=SCRAM-SHA-512 + automq.telemetry.s3.selector.kafka.sasl.jaas.config=org.apache.kafka.common.security.scram.ScramLoginModule required username="connect" password="change-me"; + ``` + + **Key points** + + - `bootstrap.servers` (required): Kafka cluster endpoints used for election. + - `topic`, `group.id`, `client.id` (optional): default to values derived from `clusterId`/`nodeId` if omitted. + - Topic management parameters such as `topic.replication.factor`, `topic.partitions`, and `topic.retention.ms` can be overridden with the same prefix. + - Any additional Kafka client settings (security protocol, SASL/SSL options, timeouts, etc.) can be supplied via `automq.telemetry.s3.selector.kafka.`. + + The selector automatically creates the election topic (1 partition by default) and keeps a background consumer alive. When the leader stops, Kafka triggers a rebalance and another node immediately takes over without requiring shared storage. + +5. **Custom SPI-based Selectors** + + The system supports custom node selection strategies through Java's ServiceLoader SPI mechanism. + + ```properties + automq.telemetry.s3.selector.type=custom-type-name + # Additional custom parameters as needed + ``` + +#### Custom Node Selection using SPI + +You can implement custom node selection strategies by implementing the `UploaderNodeSelectorProvider` interface and registering it using Java's ServiceLoader mechanism: + +1. **Implement the Provider Interface** + + ```java + public class CustomSelectorProvider implements UploaderNodeSelectorProvider { + @Override + public String getType() { + return "custom-type";

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}
