Graphsignal is an observability platform for AI agents and LLM-powered applications. It helps developers ensure AI applications run as expected and users have the best experience. With Graphsignal, developers can:

* Trace requests, runs, and sessions with full AI context.
* See latency breakdown by operations.
* Analyze model API costs for deployments, models, or users.
* Get notified about errors and anomalies.
* Monitor API, compute, and GPU utilization.

Learn more at [graphsignal.com](https://graphsignal.com).


## Install

Install Graphsignal library by running:

```
pip install graphsignal
```

Or clone and install the [GitHub repository](https://github.com/graphsignal/graphsignal-python):

```
git clone https://github.com/graphsignal/graphsignal-python.git
python setup.py install
```


## Configure

Configure Graphsignal tracer by specifying your API key directly or via `GRAPHSIGNAL_API_KEY` environment variable.

```python
import graphsignal

graphsignal.configure(api_key='my-api-key', deployment='my-model-prod-v1') 
```

To get an API key, sign up for a free account at [graphsignal.com](https://graphsignal.com). The key can then be found in your account's [Settings / API Keys](https://app.graphsignal.com/settings/api-keys) page.

Alternatively, you can add Graphsignal tracer at command line, when running your module or script. Environment variables `GRAPHSIGNAL_API_KEY` and `GRAPHSIGNAL_DEPLOYMENT` must be set.

```bash
python -m graphsignal <script>
```

```bash
python -m graphsignal -m <module>
```

## Integrate

### Automatic integration

Graphsignal **auto-instruments** and traces libraries and frameworks, such as [OpenAI](https://graphsignal.com/docs/integrations/openai/), [LangChain](https://graphsignal.com/docs/integrations/langchain/), [LlamaIndex](https://graphsignal.com/docs/integrations/llama-index/), [Hugging Face](https://graphsignal.com/docs/integrations/hugging-face/). Traces, errors, and data, such as prompts and completions, are automatically recorded and available for analysis at [app.graphsignal.com](https://app.graphsignal.com/).

Some integration examples are available in [examples](https://github.com/graphsignal/examples) repo.


### User tracking

User tracking allows grouping and visualization of user-related traces, interactions, metrics, and costs. It also enables detection of user interaction outliers and other events.

To enable user tracking, set user identifier as `user` tag for every request, e.g. in a request handler.

```python
graphsignal.set_context_tag('user', user_id)
```

If you are running a single process per user and added Graphsignal at command line, you can set the `user` tag in an environment variable.

```bash
env GRAPHSIGNAL_TAGS="user=user_id" python -m graphsignal <script>
```

### Tracing any operation

To measure and monitor operations that are not automatically instrumented, e.g. any model inference or inference API calls, wrap the code with [`start_trace()`](https://graphsignal.com/docs/reference/python-api/#graphsignalstart_trace) method or use [`@trace_function`](https://graphsignal.com/docs/reference/python-api/#graphsignaltrace_function) decorator.

```python
with graphsignal.start_trace('predict'):
    pred = model(x)
```

```python
@graphsignal.trace_function
def predict(x):
    return model(x)
```

Enable profiling to additionally record code-level statistics. Profiling is disabled by default due to potential overhead. To enable, provide [`TraceOptions`](https://graphsignal.com/docs/reference/python-api/#graphsignaltraceoptions) object.

```python
with graphsignal.start_trace('predict', options=graphsignal.TraceOptions(enable_profiling=True)):
    pred = model(x)
```

The tracer will automatically choose a profiler depending on available modules. Currently, CProfile, PyTorch Kineto and Yappi are supported. The Kineto profiler is used if `torch` module is detected and Yappi profiler is used if `yappi` module is detected. Otherwise, CProfile is used. To properly profile `asyncio` coroutines, simply `pip install yappi`.


See [API reference](https://graphsignal.com/docs/reference/python-api/) for full documentation.


### Exception tracking

For auto-instrumented libraries, or when using `@trace_function` decorator, `start_trace()` method with `with` context manager or callbacks, exceptions are **automatically** recorded. For other cases, use [`Trace.add_exception`](https://graphsignal.com/docs/reference/python-api/#graphsignalspanadd_exception).


### Data monitoring

Data, such as prompts and completions, is automatically monitored for auto-instrumented libraries. To track data metrics and record data profiles for other cases, [`Trace.set_data()`](https://graphsignal.com/docs/reference/python-api/#graphsignalspanset_data) method can be used.

```python
with graphsignal.start_trace('predict') as span:
    span.set_data('input', input_data)
```

The following data types are currently supported: `list`, `dict`, `set`, `tuple`, `str`, `bytes`, `numpy.ndarray`, `tensorflow.Tensor`, `torch.Tensor`.

Raw data samples, such as prompts and completions, are recorded by default. To disable, set `record_data_samples=False` in `graphsignal.configure`. Note, that data statistics, such as size, shape or number of missing values will still be recorded.


## Observe

[Log in](https://app.graphsignal.com/) to Graphsignal to monitor and analyze your application and monitor for issues.


## Overhead

Graphsignal tracer is very lightweight. The overhead per trace is measured to be less than 100 microseconds.


## Security and Privacy

Graphsignal tracer can only open outbound connections to `signal-api.graphsignal.com` and send data, no inbound connections or commands are possible.

Raw data samples, e.g. prompts, are recorded by default. This feature can be disabled at tracer initialization time, if necessary.


## Troubleshooting

To enable debug logging, add `debug_mode=True` to `configure()`. If the debug log doesn't give you any hints on how to fix a problem, please report it to our support team via your account.

In case of connection issues, please make sure outgoing connections to `https://signal-api.graphsignal.com` are allowed.
