Graphsignal is an AI observability platform. It helps ML engineers and MLOps teams make AI applications run faster and reliably by monitoring and analyzing performance, resources, data and errors. Graphsignal's capabilities enable full visibility into AI applications for any model, data and deployment.

* Monitor and analyze inference latency, throughput and resource utilization.
* Track GPU utilization in the context of inference.
* Get notified about errors and anomalies with full machine learning context.
* Monitor data to detect data issues and silent failures.

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


## Install

Install Graphsignal agent 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 agent 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.

To track deployments, versions and environments separately, specify a `deployment` parameter or environment variable `GRAPHSIGNAL_DEPLOYMENT`.


## Integrate

Use the following examples to integrate Graphsignal agent into your machine learning application. See integration documentation and [API reference](https://graphsignal.com/docs/reference/python-api/) for full reference. More integration examples are available in [examples](https://github.com/graphsignal/examples) repo.


### Monitoring and tracing

Graphsignal **auto-instruments** and traces libraries and frameworks, such as [OpenAI](https://graphsignal.com/docs/integrations/openai/), [LangChain](https://graphsignal.com/docs/integrations/langchain/), and many others.

To measure and monitor any other executions, e.g. 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(endpoint='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(
        endpoint='predict', 
        options=graphsignal.TraceOptions(enable_profiling=True)):
    pred = model(x)
```

The agent 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 found and Yappi profiler is used if `yappi` module is found. Otherwise, CProfile is used. To properly profile `asyncio` coroutines, just `pip install yappi`.


### 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.set_exception`](https://graphsignal.com/docs/reference/python-api/#graphsignalendpointtraceset_exception) method.


### Data monitoring

Data 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/#graphsignalendpointtraceset_data) method can be used.

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

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

**No raw data is recorded** by the agent, only statistics such as size, shape or number of missing values.


## Observe

After everything is setup, [log in](https://app.graphsignal.com/) to Graphsignal to monitor and analyze execution performance and monitor for issues.


## Overhead

Graphsignal agent is very lightweight. While all traces are monitored, Graphsignal agent only samples and records certain traces, automatically limiting the overhead. The overhead per trace is measured to be less than 100 microseconds.


## Security and Privacy

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

No code or data is sent to Graphsignal cloud, only statistics and metadata.


## 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://agent-api.graphsignal.com` are allowed.
