Integrate Datadog with StarRocks

This topic describes how to integrate your StarRocks cluster with Datadog, a monitoring and security platform.

Prerequisites

Before getting started, you must have the following software installed on your instances:

• Datadog Agent
• Python

NOTE

When you install Datadog Agent for the first time, Python is also installed as a dependency. We recommend you use this Python in the following steps.

Prepare StarRocks source code

Since Datadog does not provide the integration kit for StarRocks yet, you need to integrate them using the source code.

1. Launch a terminal, navigate to a local directory to which you have both read and write access, and run the following command to create a dedicated directory for StarRocks source code.

   mkdir -p starrocks

2. Download the StarRocks source code package using the following command or on GitHub to the directory you created.

   cd starrocks
   # Replace <starrocks_ver> with the actual version of StarRocks, for example, "2.5.2".
   wget https://github.com/StarRocks/starrocks/archive/refs/tags/<starrocks_ver>.tar.gz

3. Extract the files in the package.

   # Replace <starrocks_ver> with the actual version of StarRocks, for example, "2.5.2".
   tar -xzvf <starrocks_ver>.tar.gz --strip-components 1

Install and configure FE integration kit

1. Install Datadog integration kit for FE using source code.

   /opt/datadog-agent/embedded/bin/pip install contrib/datadog-connector/starrocks_fe

2. Create the FE integration configuration file /etc/datadog-agent/conf.d/starrocks_fe.d/conf.yaml.

   sudo mkdir -p /etc/datadog-agent/conf.d/starrocks_fe.d
   sudo cp contrib/datadog-connector/starrocks_fe/datadog_checks/starrocks_fe/data/conf.yaml.example /etc/datadog-agent/conf.d/starrocks_fe.d/conf.yaml

3. Modify the FE integration configuration file /etc/datadog-agent/conf.d/starrocks_fe.d/conf.yaml.

   Examples of some important configuration items:

   Config	Example	Description
   fe_metric_url	http://localhost:8030/metrics	The URL used to access the StarRocks FE metrics.
   metrics	- starrocks_fe_*	Metrics to be monitored on FE. You can use wildcards * to match the configuration items.

Install and configure BE integration kit

1. Install Datadog integration kit for BE using source code.

   /opt/datadog-agent/embedded/bin/pip install contrib/datadog-connector/starrocks_be

2. Create the BE integration configuration file /etc/datadog-agent/conf.d/starrocks_be.d/conf.yaml.

   sudo mkdir -p /etc/datadog-agent/conf.d/starrocks_be.d
   sudo cp contrib/datadog-connector/starrocks_be/datadog_checks/starrocks_be/data/conf.yaml.example /etc/datadog-agent/conf.d/starrocks_be.d/conf.yaml

3. Modify the BE integration configuration file /etc/datadog-agent/conf.d/starrocks_be.d/conf.yaml.

   Examples of some important configuration items:

   Config	Example	Description
   be_metric_url	http://localhost:8040/metrics	The URL used to access the StarRocks BE metrics.
   metrics	- starrocks_be_*	Metrics to be monitored on BE. You can use wildcards * to match the configuration items.

Restart Datadog Agent

Restart Datadog Agent to allow the configuration to take effect.

sudo systemctl stop datadog-agent
sudo systemctl start datadog-agent

Verify integration

For instructions to verify the integration, see Datadog Application.

Uninstall integration kits

You can uninstall the integration kits when you no longer need them.

• To uninstall FE integration kit, run the following command:

  /opt/datadog-agent/embedded/bin/pip uninstall datadog-starrocks-fe

• To uninstall BE integration kit, run the following command:

  /opt/datadog-agent/embedded/bin/pip uninstall datadog-starrocks-be
