Fluentd Metrics Monitoring
Monitoring via HTTP
td-agent has a built-in monitoring agent to retrieve internal metrics in JSON via HTTP. Add the following lines to your configuration file.
disable_node_info (default true): Send system metrics, CPU / Memory / Disk, or not.
Restart the agent and get the metrics via HTTP.
Monitoring with Prometheus or Datadog
Additionally, td-agent works with monitoring tools such as Prometheus, Datadog, etc. Our recommendation is to use Prometheus because Treasure Data collaborates with the CNCF (Cloud Native Computing Foundation).
ruby processes (parent and child) are executed. Ensure that these processes are running.
For td-agent on Linux, you can check the process status with the following command. You see the status of two processes if there are no issues.
td-agent opens the following ports by default. We recommend checking the availability of these ports.
TCP 0.0.0.0 8888 (HTTP)
TCP 0.0.0.0 24224 (Forward)
If you don’t send any data, the daemon doesn’t do anything.
A debug port for local communication is also opened.
TCP 127.0.0.1 24230
