Details of the instrumentation agents across your hosts and clusters.

The Instrumentation tab enables you to track the health, configuration, and status of your agents running on different hosts and clusters in your organization.

You can filter the list by Agent type, Environment, Version, Service, or Status. Use the search bar to filter the list by cluster name or host name, which is particularly useful for large-scale environments.

Select Add filter to filter by OS type.

To save the report as a CSV file, select the Download icon. The exported file includes any currently applied filters.

Summary metrics for hosts

You can access high-level insights into your agent deployment:

  • Total agents: Displays the total count of active agents currently reporting to the platform.

  • Agent types: Indicates the number of agent types, such as Java, Node.js, .NET deployed in your environment.

  • Agents out-of-date: Count of the agents that are not on running the latest version. Select the card to view the full list.

  • Disconnected agents: Count of the agents across all hosts that are not reporting any signal within a period. The default period is 90 seconds. Select the card to view the details.

Details of agents running on hosts

The list provides a granular view of each instrumentation agent:

Column Description
Type The specific language agent, such as Java, Node.js, .NET.
Host name The name of the host where the agent is running.
Environment The deployment environment associated with the agent.
Version The specific version of the agent currently in use. Highlights the version that is out-of-date.
Service The service or application associated with the agent.
Last status check The timestamp of the most recent heartbeat from the agent.
Status

Represents the health of the connection- whether the agent is actively communicating with the server. It has two values- Connected or Disconnected.

Connected: The agent has reported a heartbeat signal within the last period. The default period is 90 seconds.

Disconnected: The agent has not reported a heartbeat signal within the last period. The default period is 90 seconds.

Agents that do not send a heartbeat signal within a five-minute window are automatically removed from the list.

Select an agent from the list to view the following details:

  • agent summary

  • effective configuration of the agent. You can download or copy the environment variables.

  • associated service in Splunk APM.
