Execution Tags allow you to dynamically add dimensions to your Lambda function invocations so that they can be identified, searched for, and filtered in Lumigo.

They can be utilized to find specific invocations and create custom widgets, helping you simplify the complexity of monitoring distributed applications.

Configuring Execution Tags

From the command line, install the lumigo tracer

pip install lumigo_tracer

npm install @lumigo/tracer --save

Adding for Auto-Traced functions
Add an execution tag to your handler’s code

from lumigo_tracer import add_execution_tag

add_execution_tag(“user_id”,user_id)

const lumigo = require('@lumigo/tracer');

lumigo.addExecutionTag('<key>', '<value>');

Adding for Manual traced functions

from lumigo_tracer import lumigo_tracer
from lumigo_tracer import add_execution_tag

@lumigo_tracer(token='YOUR-TOKEN-HERE')
def my_lambda(event, context):
    print('I can finally troubleshoot!')
    add_execution_tag(“user_id”,user_id)

const lumigo = require('@lumigo/tracer')({ token: '<your_lumigo_token>' });

lumigo.addExecutionTag('<key>', '<value>');

Auto execution tags from the event

To configure execution tags that will be driven directly from the event, add an environment variable to the Lambda function with the name of the relevant key. We support only the python and node runtimes.

For example, to configure an auto tag from the key product_id, add the environment variable:

To configure multiple auto tags, such as product_id and source, add:

For a nested field, such as name inside the value of the key source, the syntax is:

Execution Tags naming limits and requirements

• Execution tags can be added only to a traced function
• The maximum number of tags is 50.
• Key length must be between 1 and 50.
• Value length must be between 1 and 70.
