Edge Delta Kubernetes Trace Source
2 minute read
Overview
You can use the Kubernetes Trace source node to ingest eBPF traces for specific resources from the Linux kernel.
- outgoing_data_types: trace
Example Configuration

nodes:
- name: Kubernetes_Trace_Input
type: k8s_trace_input
Required Parameters
name
A descriptive name for the node. This is the name that will appear in pipeline builder and you can reference this node in the YAML using the name. It must be unique across all nodes. It is a YAML list element so it begins with a -
and a space followed by the string. It is a required parameter for all nodes.
nodes:
- name: <node name>
type: <node type>
type: k8s_trace_input
The type
parameter specifies the type of node being configured. It is specified as a string from a closed list of node types. It is a required parameter.
nodes:
- name: <node name>
type: <node type>
Optional Parameters
exclude
The exclude
parameter is used to excluded traces from certain namespaces from being ingested by the agent. It is specified in OTEL format with Golang regex or full text. If exclude
is specified it drops traces that match its Golang regex rules. Exclude is optional.
- If
include
is specified as well asexclude
, then traces matching ininclude
are passed unless they are dropped byexclude
.
nodes:
- name: <node name>
type: k8s_trace_input
include:
- k8s.namespace.name=.*
exclude:
- k8s.namespace.name=test
include
The include
parameter is used to specify namespaces from which traces should be ingested by the agent. It is specified in OTEL format with Golang regex or full text. If exclude
is also specified, then traces matching in include
are ingested unless they are dropped by exclude
. Include is optional.
nodes:
- name: <node name>
type: k8s_trace_input
include:
- k8s.namespace.name=.*
source_metadata
The source_metadata
parameter is used to define which detected resources and attributes to add to each data item as it is ingested by the Edge Delta agent. In the GUI you can select:
- Required Only: This option includes the minimum required resources and attributes for Edge Delta to operate.
- Default: This option includes the required resources and attributes plus those selected by Edge Delta
- High: This option includes the required resources and attributes along with a larger selection of common optional fields.
- Custom: With this option selected, you can choose which attributes and resources to include. The required fields are selected by default and can’t be unchecked.
Based on your selection in the GUI, the source_metadata
YAML is populated as two dictionaries (resource_attributes
and attributes
) with Boolean values.
See Choose Data Item Metadata for more information on selecting metadata.
