# Graphsignal
|
||
|
|
|
||
|
|
This page covers how to use the Graphsignal to trace and monitor LangChain.
|
||
|
|
|
||
|
|
## Installation and Setup
|
||
|
|
|
||
|
|
- Install the Python library with `pip install graphsignal`
|
||
|
|
- Create free Graphsignal account [here](https://graphsignal.com)
|
||
|
|
- Get an API key and set it as an environment variable (`GRAPHSIGNAL_API_KEY`)
|
||
|
|
|
||
|
|
## Tracing and Monitoring
|
||
|
|
|
||
|
|
Graphsignal automatically instruments and starts tracing and monitoring chains. Traces, metrics and errors are then available in your [Graphsignal dashboard](https://app.graphsignal.com/). No prompts or other sensitive data are sent to Graphsignal cloud, only statistics and metadata.
|
||
|
|
|
||
|
|
Initialize the tracer by providing a deployment name:
|
||
|
|
|
||
|
|
```python
|
||
|
|
import graphsignal
|
||
|
|
|
||
|
|
graphsignal.configure(deployment='my-langchain-app-prod')
|
||
|
|
```
|
||
|
|
|
||
|
|
In order to trace full runs and see a breakdown by chains and tools, you can wrap the calling routine or use a decorator:
|
||
|
|
|
||
|
|
```python
|
||
|
|
with graphsignal.start_trace('my-chain'):
|
||
|
|
chain.run("some initial text")
|
||
|
|
```
|
||
|
|
|
||
|
|
Optionally, enable profiling to record function-level statistics for each trace.
|
||
|
|
|
||
|
|
```python
|
||
|
|
with graphsignal.start_trace(
|
||
|
|
'my-chain', options=graphsignal.TraceOptions(enable_profiling=True)):
|
||
|
|
chain.run("some initial text")
|
||
|
|
```
|
||
|
|
|
||
|
|
