Pulsar

Supported OS Linux Windows Mac OS

Integration version2.2.2

Overview

This check monitors Pulsar through the Datadog Agent.

Setup

Follow the instructions below to install and configure this check for an Agent running on a host. For containerized environments, see the Autodiscovery Integration Templates for guidance on applying these instructions.

Installation

The Pulsar check is included in the Datadog Agent package. No additional installation is needed on your server.

Configuration

Edit the pulsar.d/conf.yaml file, in the conf.d/ folder at the root of your Agent’s configuration directory to start collecting your pulsar performance data. See the sample pulsar.d/conf.yaml for all available configuration options.
Restart the Agent.

Validation

Run the Agent’s status subcommand and look for pulsar under the Checks section.

Log collection

The Pulsar log integration supports Pulsar’s default log format. Clone and edit the integration pipeline if you have a different format.
Collecting logs is disabled by default in the Datadog Agent. Enable it in your datadog.yaml file:
```
logs_enabled: true
```
Uncomment and edit the logs configuration block in your pulsar.d/conf.yaml file. Change the path parameter value based on your environment. See the sample pulsar.d/conf.yaml for all available configuration options.
```
 logs:
   - type: file
     path: /pulsar/logs/pulsar.log
     source: pulsar
```
Restart the Agent

Events

The Pulsar integration does not include any events.

Service Checks

pulsar.openmetrics.health
Returns CRITICAL if the Agent is unable to connect to the OpenMetrics endpoint, otherwise returns OK.
Statuses: ok, critical
