Overview
Get metrics from gnatsd_streaming service in real time to:
- Visualize and monitor gnatsd_streaming states
- Be notified about gnatsd_streaming failovers and events.
Setup
The gnatsd_streaming check is not included in the Datadog Agent package, so you need to install it.
Installation
For Agent v7.21+ / v6.21+, follow the instructions below to install the gnatsd_streaming check on your host. See Use Community Integrations to install with the Docker Agent or earlier versions of the Agent.
Run the following command to install the Agent integration:
datadog-agent integration install -t datadog-gnatsd_streaming==<INTEGRATION_VERSION>
Configure your integration similar to core integrations.
Configuration
Edit the gnatsd_streaming.d/conf.yaml file in the conf.d/ folder at the root of your Agent’s configuration directory to start collecting your GnatsD streaming metrics.
See the sample gnatsd_streaming.d/conf.yaml for all available configuration options.
Restart the Agent
Validation
Run the Agent’s status subcommand and look for gnatsd_streaming under the Checks section.
Compatibility
The gnatsd_streaming check is compatible with all major platforms
