The Users view provides an overview of all users. It also offers an in-depth look into individual users. It’s easy to map data in ABV to individual users. Just pass a unique identifier as the userId when you create a trace. This can be a username, email, or any other unique identifier. The userId is optional, but using it helps you get more from ABV. See the integration docs to learn more.

​
Implementation with Python SDK

Install package 
pip install abvdev
When using the @observe() decorator and initialization via constructor arguments: 
from abvdev import observe
from abvdev import ABV

# ABV client initialization          
abv = ABV(
    api_key="sk-abv-...", # your api key here
    host="https://app.abv.dev", # host="https://eu.app.abv.dev", for EU region
)
 
@observe()
def process_request(): 
    # Add to the current trace
    abv.update_current_trace(user_id="user_12345")
 
    # ...your processing logic...
    return "Processing complete"


# call the function
process_request()
When creating spans directly: 
from abvdev import ABV

# ABV client initialization          
abv = ABV(
    api_key="sk-abv-...", # your api key here
    host="https://app.abv.dev", # host="https://eu.app.abv.dev", for EU region
)
 
# You can set the user_id when creating the root span via update_trace
with abv.start_as_current_span(
    name="process-user-request"
) as root_span:
    # Add user_id to the trace
    root_span.update_trace(user_id="user_12345")
 
    # All spans in this trace will be associated with this user
    with root_span.start_as_current_observation(
        as_type='generation',
        name="generate-response",
        model="gpt-4o"
    ) as gen:
        # ...generate response...
        pass
You can also update the user_id of the current trace without a direct reference to a span: 
from abvdev import ABV

# ABV client initialization          
abv = ABV(
    api_key="sk-abv-...", # your api key here
    host="https://app.abv.dev", # host="https://eu.app.abv.dev", for EU region
)
 
with abv.start_as_current_span(name="handle-user-interaction"):
    # Add user_id to the current trace
    abv.update_current_trace(user_id="user_12345")

​
Implementation with JS/TS SDK

Install packages 
npm install @abvdev/tracing @abvdev/otel @opentelemetry/sdk-node dotenv
Add credentials Add your ABV credentials to your environment variables. Make sure that you have a .env file in your project root and a package like dotenv to load the variables. Createinstrumentation.ts file and use dotenv package to load the variables. Additional parameters are provided to get trace visible in the UI immediately. Import the instrumentation.ts file at the top of your application. When using the context manager: 
import "./instrumentation"; // Must be the first import

import {
  startActiveObservation,
  startObservation,
  updateActiveTrace,
} from "@abvdev/tracing";
 
async function main() {
    await startActiveObservation("context-manager", async (span) => {
        span.update({
            input: { query: "What is the capital of France?" },
        });
        
        updateActiveTrace({
            userId: "user-123",
        });
    });
}

main();
When using the observe wrapper: 
import "./instrumentation"; // Must be the first import
import { observe, updateActiveTrace } from "@abvdev/tracing";
 
// An existing function
async function fetchData(source: string) {
  updateActiveTrace({
    userId: "user-123",
  });
 
  // ... logic to fetch data
  return { data: `some data from ${source}` };
}
 
// Wrap the function to trace it
const tracedFetchData = observe(fetchData, {
  name: "observe-wrapper",
});
 
async function main() {
    const result = await tracedFetchData("API");
}

main();
When creating spans manually: 
import "./instrumentation"; // Must be the first import
import { startObservation } from "@abvdev/tracing";
 
const span = startObservation("manual-observation", {
  input: { query: "What is the capital of France?" },
});
 
span.updateTrace({
  userId: "user-123",
});
 
span.update({ output: "Paris" }).end();
See JS/TS SDK docs for more details.

​
View all users

The user list provides an overview of all users that have been tracked by ABV. It makes it simple to segment by overall token usage, number of traces, and user feedback.

​
Individual user view

The individual user view provides an in-depth look into a single user. Explore aggregated metrics or view all traces and feedback for a user. You can deep link to this view via the following URL format: https://<hostname>/project/{projectId}/users/{userId}
