integrate with Nuxtjs but cannot see any transaction in APM

[cwhsu1984]

This is how I init apm in Dockerfile.

CMD node -r ./server/node_modules/elastic-apm-node/start.js ./server/index.mjs

This is the env config, and we run containers in kubernetes.

ELASTIC_APM_ENVIRONMENT=Staging
ELASTIC_APM_SERVICE_NAME=Lego
ELASTIC_APM_SERVER_URL=http://my-apm-server
ELASTIC_APM_TRANSACTION_SAMPLE_RATE=1
ELASTIC_APM_CAPTURE_BODY=all
ELASTIC_APM_USE_ELASTIC_TRACEPARENT_HEADER=true
ELASTIC_APM_TRACE_CONTINUATION_STRATEGY=restart
ELASTIC_APM_LOG_LEVEL=trace

I check the service in APM, but there is no data.

But If I look at Metrics tab, the cpu and memory related info is collected

Below is the container log. And I suspect it's due to the message "no active transaction found - cannot build new span".
I already try to adjust ELASTIC_APM_TRACE_CONTINUATION_STRATEGY into different settings, but still no luck.

What is the possible cause of this?
Any suggestion on how to debug this?

[trentm]

@cwhsu1984 Hi. Thanks for the issue. There are a few things to note here, but ultimately, this APM agent is not currently able to instrument NuxtJS 3 apps.

instrumenting the dev server (somewhat)

I created a basic Nuxt 3 app using the getting started doc: https://nuxt.com/docs/getting-started/introduction
and added one API endpoint.
My repo is here:
https://github.com/trentm/nuxtplay

I was able to get some tracing data for HTTP requests to the server when using the dev server:

NODE_OPTIONS=--require=elastic-apm-node/start npm run dev -- -o

Then I would get traces something like the following (this is a text-based summary of traces rather than showing screenshots from Kibana):

    trace d9e0fd
    `- transaction 52cef6 "GET unknown route" (0.729ms, GET http://localhost:3000/_nuxt/@id/virtual:nuxt:/Users/trentm/tmp/nuxtplay/.nuxt/pages.mjs -> 200)
    trace 779ade
    `- transaction e31389 "GET unknown route" (1.338ms, GET http://localhost:3000/_nuxt/node_modules/nuxt/dist/app/components/welcome.vue?vue&type=style&index=0&scoped=8e92eaa8&lang.css -> 200)
    trace b27ced
    `- transaction 0c716a "GET unknown route" (0.194ms, GET http://127.0.0.1:63764/__nuxt_vite_node__/invalidates -> 200)

...

    trace b0ed13
    `- transaction c25a09 "GET unknown route" (67.971ms, GET http://localhost:3000/api/hello -> 200)
       `- span 4616b8 "GET localhost:3000" (63.624ms, http)

These transactions and spans are coming from automatic instrumentation of the http library used when the Nuxt dev server is running.

This tracing is, of course, limited because the APM agent (elastic-apm-node) doesn't know anything about Nuxt routing, so all transactions are named {method} unknown route.

No tracing for the production server

When I build and run the production (non-dev) server:

npm run build
NODE_OPTIONS=--require=elastic-apm-node/start node .output/server/index.mjs

This does not work.
The first issue is that the built server is an ES module (ESM) as opposed to CommonJS.
Support for instrumentating ES modules is experimental and limited. It is discussed here: https://www.elastic.co/guide/en/apm/agent/nodejs/current/esm.html

Ideally we would be able to get some instrumentation of the ESM code by using the additional --experimental-loader=elastic-apm-node/loader.mjs option:

node --require=elastic-apm-node/start.js --experimental-loader=elastic-apm-node/loader.mjs .output/server/index.mjs

This partially works. For example, when manually making a call to just the added "/api/hello" endpoint in my small Nuxt app:

% curl localhost:3000/api/hello
Hello World!

I successfully get a trace from the APM agent:

    trace e2e9f1
    `- transaction d5f7f2 "GET unknown route" (10.366ms, GET http://localhost:3000/api/hello -> 200)

However, when loading the full app in a browser (http://localhost:3000), I get a 500 error in the browser and this in the app log:

[nuxt] [request error] [unhandled] [500] The requested module 'vue/server-renderer' does not provide an export named 'renderToString'

  at async Object.handler (./.output/server/chunks/runtime.mjs:2887:19)
  at async Server.toNodeHandle (./.output/server/chunks/runtime.mjs:3157:7)

This is almost certainly a bug in the underlying library that the APM agent is using to hook into ES module imports. That hooking is breaking the vue/server-renderer module. That library, import-in-the-middle, is under active development: https://github.com/nodejs/import-in-the-middle/pulls
I expect the handling of this will improve over time.

Bundling

Finally, if I understand correctly, the built server code uses a bundler (esbuild?). Currently this APM agent does not support instrumenting libraries used in bundled code. Node.js core libraries (like http) can still be instrumented, but any other libraries cannot. That may mean somewhat limited tracing data.

If you are mainly interested in HTTP incoming and outgoing spans, then this may be fine for you.

options

I have not tried this, but perhaps the Nuxt tsconfig could be changed to build a CommonJS server, rather than ESM code. Then that might allow the built server to be instrumented without the --experimental-loader=elastic-apm-node/loader.mjs loader that is causing issues.

I would like to thank you for the very detailed response to the thread.
Ok, I'll try to survey other possibilities.

[trentm]

Okay, thanks. I'll close this issue now. Please feel free to re-open, or create a new one if you have other questions. I'm sorry this doesn't work out of the box for you.

However, when loading the full app in a browser (http://localhost:3000), I get a 500 error in the browser and this in the app log:

Actually this exact issue was just recently fixed in import-in-the-middle: nodejs/import-in-the-middle#139
The next release of elastic-apm-node will include a fix for this. So, that means that:

1. You should be able to get limited instrumentation of Nuxt 3 apps via node --require=elastic-apm-node/start.js --experimental-loader=elastic-apm-node/loader.mjs .output/server/index.mjs.
2. Limitation: Because the built server is bundled the instrumentation will be limited to core Node.js modules (i.e. mainly http and https usage). Other modules, like express or pg, etc. will not be instrumented.
3. Limitation: The APM agent doesn't know about Nuxt routing, so while incoming HTTP requests will be instrumented the transaction name won't be as useful as it could be.

[cwhsu1984]

I have tried the --experimental-loader with 4.7.0, and saw the same error that you show previously.
This is the result that I see in the APM.

I just tried the same with 4.7.1, and unfortunately I saw another issue as below. My application crashed after some time, so it seems 4.7.1 still not solving the usage for Nuextjs.

SyntaxError: The requested module 'vue' does not provide an export named 'unref'

It looks like that particular crash will be fixed when we have a release with this update: #4162

[cwhsu1984]

I'm not sure exactly how I should apply this, so this is what I did.

...
WORKDIR /app/server
RUN npm install elastic-apm-node@4.7.1
RUN npm install import-in-the-middle@1.10.0
WORKDIR /app
COPY --from=builder /app/.env.* ./
COPY --from=builder /app/.output .

CMD node -r ./server/node_modules/elastic-apm-node/start.js --experimental-loader=./server/node_modules/elastic-apm-node/loader.mjs ./server/index.mjs

Still the same error.

@cwhsu1984 Sorry to imply that we had a release with that fix. We do not yet have a release of this APM agent with the update to the import-in-the-middle library that you need.

[cwhsu1984]

Is there a timeline or schedule date for the next release?
