Infino

Infino is a scalable telemetry store designed for logs, metrics, and traces. Infino can function as a standalone observability solution or as the storage layer in your observability stack.

This example shows how one can track the following while calling OpenAI and ChatOpenAI models via LangChain and Infino:

  • prompt input
  • response from ChatGPT or any other LangChain model
  • latency
  • errors
  • number of tokens consumed

Initializing​

# Install necessary dependencies.

Example 1: LangChain OpenAI Q&A; Publish metrics and logs to Infino​

Create Metric Charts​

We now use matplotlib to create graphs of latency, errors and tokens consumed.

    plt.subplots_adjust(bottom=0.2)
    plt.xticks(rotation=25)
    ax = plt.gca()
    xfmt = md.DateFormatter("%Y-%m-%d %H:%M:%S")
    ax.xaxis.set_major_formatter(xfmt)

    # Create the plot
    plt.plot(dates, y)

    # Set labels and title
    plt.xlabel("Time")
    plt.ylabel("Value")
    plt.title(title)

    plt.show()
