data collector on node.js

oadiaobong — Fri, 15 Sep 2023 12:59:36 GMT

I am unable to create a data collector on my node.js application. I came across this doc " For the Node.js agent, you can create a method data collector only using the addSnapshotData() Node.js API, not the Controller UI as described here. See Node.js Agent API Reference".

I have 2 questions;

how do I determine the value and key to use
where do I add addSnapshotData()

Hi @Adiaobong.Odungide,

I've reached out to the Docs team looking for some clarification. I will report back when I have more info.

Hi @Adiaobong.Odungide,

Sorry for the late reply, this is what I heard back from the Docs team.

The `key` is whatever you want to use to identify the custom data; the `value` is the data you want to capture and attach to the snapshot. The call to `txn.addSnapshotData()` can occur anywhere in your application where a transaction is in progress, either programmatically created via `appd.startTransaction(...)` or auto-discovered and retrieved via `appd.getTransaction(request)`. To add custom snapshot data to a transaction that's already being detected and reported, `getTransaction()` would be the required approach.
