SignalFx Smart Agent commands reference 🔗
This topic provides commonly used commands for the Smart Agent.
Note
The SignalFx Smart Agent has reached End of Support. While the agent can capture and export telemetry to Splunk Observability Cloud, Splunk no longer provides any support, feature updates, security, or bug fixes. Such requests are not bound by any SLAs.
To see commonly used commands for the Splunk Distribution of OpenTelemetry Collector, see Collector for Kubernetes commands reference.
The standard ports for the Smart Agent are 9080 and 8095. The default configuration is stored in /etc/signalfx/agent.yaml.
Note
When you deploy the agent as a DaemonSet on Kubernetes clusters, the agent configuration is managed by the ConfigMap of the agent.
