Java
This article explains how to use it.
- Basic knowledge of Java
- Basic knowledge of Fluentd
- Java 7 or higher
Please refer to the following documents to install fluentd:
<source>
@type forward
port 24224
</source>
<match fluentd.test.**>
@type stdout
</match>
Restart agent after configuring.
# for rpm/deb only
$ sudo /etc/init.d/td-agent restart
# or systemd
$ sudo systemctl restart td-agent.service
Add the following dependency configuration to
pom.xml. The logger's revision information can be found in CHANGES.txt:<dependencies>
...
<dependency>
<groupId>org.fluentd</groupId>
<artifactId>fluent-logger</artifactId>
<version>${logger.version}</version>
</dependency>
...
</dependencies>
Here's a sample Java test application:
import java.util.HashMap;
import java.util.Map;
import org.fluentd.logger.FluentLogger;
public class Main {
private static FluentLogger LOG = FluentLogger.getLogger("fluentd.test");
public void doApplicationLogic() {
// ...
Map<String, Object> data = new HashMap<String, Object>();
data.put("from", "userA");
data.put("to", "userB");
LOG.log("follow", data);
// ...
}
}
Executing the above program will send the logs to Fluentd:
$ java -jar test.jar
The logs should be output to
/var/log/td-agent/td-agent.log or the standard output of the Fluentd process via stdout output plugin.- List of Plugin References
For high-traffic websites (more than 5 application nodes), we recommend using the high-availability configuration for
td-agent. This will improve the reliability of data transfer and query performance.Monitoring Fluentd itself is also important. The article below describes the general monitoring methods for
td-agent:If this article is incorrect or outdated, or omits critical information, please let us know. Fluentd is an open-source project under Cloud Native Computing Foundation (CNCF). All components are available under the Apache 2 License.
