Graphsignal enables full visibility into your application. It provides latency breakdowns by chains and tools, exceptions with full context, data monitoring, compute/GPU utilization, OpenAI cost analytics, and more.Installation and Setupâ€‹Install the Python library with pip install graphsignalCreate free Graphsignal account hereGet an API key and set it as an environment variable (GRAPHSIGNAL_API_KEY)Tracing and Monitoringâ€‹Graphsignal automatically instruments and starts tracing and monitoring chains. Traces and metrics are then available in your Graphsignal dashboards.Initialize the tracer by providing a deployment name:import graphsignalgraphsignal.configure(deployment='my-langchain-app-prod')To additionally trace any function or code, you can use a decorator or a context manager:@graphsignal.trace_functiondef handle_request():        chain.run("some initial text")with graphsignal.start_trace('my-chain'):    chain.run("some initial text")Optionally, enable profiling to record function-level statistics for each trace.with graphsignal.start_trace(        'my-chain', options=graphsignal.TraceOptions(enable_profiling=True)):    chain.run("some initial text")See the Quick Start guide for complete setup instructions.PreviousGPT4AllNextGrobidInstallation and SetupTracing and
