Sending data to another collector

[bhaskarbanerjee]

Question -
I am trying to use this opensource and send data to another collector.
I am assuming that does not require the prerequisite of connecting my aws account with Baselime.
I have built the layer using scripts/publish.sh and created a layer out of that.
I have attached the layer to my lambda and am setting up the following ENV vars

AWS_LAMBDA_EXEC_WRAPPER /opt/baselime
BASELIME_ACTUAL_HANDLER app.handler
BASELIME_API_KEY 0123456789 (a ficticious key)
COLLECTOR_URL my_collector_url:port
OTEL_LOG_LEVEL DEBUG

My lamnbda's logs show no errors but the collectior doesn't receive any data either. Additionally, I do not see any console out from this layer. Seeking your suggestions on how to proceed with this.

My lambda handler is also set to app.handler.

Hey @bhaskarbanerjee

Do you see any debug logs from the sdk you should see a lot with the OTEL_LOG_LEVEL set to "debug"

just fyi the log level needs to be all lower case.

You can find the code for the tracer here https://github.com/baselime/node-opentelemetry/blob/main/src/baselime.ts

Thanks @Ankcorn Here are the logs.

It doesn't look like you are creating any spans.

I'd recommend installing our node-opentelemetry package and using the withOpentelemetry middleware for lambda from it to trace your lambda function

[bhaskarbanerjee]

I am trying a simple hello world app. Do I need to explicitly create spans?

`'use strict';

exports.handler = async (event) => {

console.log("Hello World")
return {
statusCode: 200,
body: JSON.stringify('Hello from Lambda!!'),
};
};`

[bhaskarbanerjee]

Doesn't the layer work out of the box i.e. adding the layer and setting ENV VARs? Or is a code change in the lambda MUST to invoke/utilize this layer?

[bhaskarbanerjee]

@Ankcorn similar to https://baselime.io/docs/sending-data/lambda-extension/

[Ankcorn]

You need to change the code.

Would look something like this

const { withOpentelemetry } = require('@baselime/node-opentelemetry/lambda');

exports.handler = withOpentelemetry((event) => {
    return {
        statusCode: 200,
        body: JSON.stringify('Hello from Lambda!!'),
    };
});

If you are using the tag system and are signed up to baselime you can do it without code changes but otherwise you need to import the middleware

[bhaskarbanerjee]

OK, Tried but it ended in an error. Have removed the layer too.

@Ankcorn

[bhaskarbanerjee]

packed @baselime/node-opentelemetry in the node_modules

[bhaskarbanerjee]

@Ankcorn slight change to the code but now a different error

`const { baselime } = require('@baselime/node-opentelemetry');

exports.handler = baselime.withOpentelemetry((event) => {
return {
statusCode: 200,
body: JSON.stringify('Hello from Lambda!!'),
};
});
`
