Route
2 minute read
Overview
The Route node passes logs to a specific path depending on a condition it evaluates. The path is connected to a specific output using the Pipeline Builder or by adding a path parameter to the links section in the YAML configuration. There is a default unmatched path that can route all remaining unmatched logs to a particular downstream node. If this is not specified the unmatched logs are not routed downstream. This is specified using the Pipeline Builder or by adding an unmatched
path to the links section in the configuration YAML.

Example Configuration
- name: item_router
type: route
paths:
- path: "pre-splunk"
condition: regex_match(item["body"], "(?i)ERROR")
- path: "ns=edgedelta"
condition: item["resource"]["k8s.namespace.name"] == "edgedelta"
links:
- from: source_node
to: item_router
- from: item_router
path: pre-splunk
to: next_node1
- from: item_router
path: ns=edgedelta
to: next_node2
- from: route
path: unmatched
to: other_output
Required Parameters
name
A descriptive name for the node. This is the name that will appear in Visual Pipelines 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: route
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>
paths
The paths parameter defines the paths and their expressions for matching logs. At least one path is required.
- path is the name of the sub-path. This name is referenced with the path parameter in the links section
- condition is a condition to evaluate if the log item should be sent to this path. The format is Common Expression Language (CEL) and you can use CEL macros.
- name: <node name>
type: route
paths:
- path: "pre_elastic"
condition: regex_match(item["body"], "(?i)ERROR")
- path: "ns=edgedelta"
condition: item["resource"]["k8s.namespace.name"] == "edgedelta"
Optional parameters
exit_if_matched
The exit_if_matched
parameter stops evaluation of further paths if a log matches the parent path. It is specified as a Boolean and the default is false. It is optional.
- name: <node name>
type: route
paths:
- path: "<path name>"
condition: <matching condition expression>
exit_if_matched: true
- path: "<path name>"
condition: <matching condition expression>
