Identifying the Symptom

One common issue users encounter is the Datadog Agent not collecting metrics from Zookeeper. This can manifest as missing data in your Datadog dashboards or alerts related to Zookeeper metrics not triggering as expected.

Exploring the Issue

The primary reason for this issue is that Zookeeper metrics collection is either not enabled, or the Datadog Agent does not have the necessary permissions to access the Zookeeper instance. Without proper configuration, the agent cannot retrieve the required metrics.

Common Error Messages

When this issue occurs, you might see error messages in the Datadog Agent logs indicating a failure to connect to Zookeeper or missing configuration settings.

Steps to Fix the Issue

First, ensure that Zookeeper metrics collection is enabled in your Datadog Agent configuration. You can do this by editing the zookeeper.d/conf.yaml file located in the conf.d directory of your Datadog Agent installation.

init_config:instances: - host: localhost port: 2181

Make sure the host and port settings match your Zookeeper instance configuration.

Step 2: Verify Agent Permissions

Ensure that the Datadog Agent has the necessary permissions to access the Zookeeper instance. This might involve configuring network access rules or updating security settings on your Zookeeper server.

Step 3: Restart the Datadog Agent

After making configuration changes, restart the Datadog Agent to apply them. Use the following command:

sudo service datadog-agent restart

Alternatively, you can use the Datadog Agent command line interface to restart the agent.

Step 4: Verify Metrics Collection
