HoneyHive combines logs, metrics, and traces into a unified data model, leveraging the concept of high cardinality to provide a comprehensive view of your AI system’s performance and behavior. By consolidating these traditionally separate observability pillars into a single, flexible event-based structure, we enable developers to gain deeper insights and perform more sophisticated analyses. This approach offers several key benefits:

  • Unified Context: Each event captures not just raw data, but also the surrounding context, allowing for more meaningful correlations and insights.
  • Flexible Querying: High cardinality enables precise filtering and aggregation across multiple dimensions, facilitating complex analyses and troubleshooting.
  • Scalability: The event-based model scales efficiently with the growing complexity of AI systems and the increasing volume of observability data.
  • Faster Debugging: The ability to trace a request through various components while simultaneously accessing logs and metrics streamlines the debugging process.

​
Introducing Events

The base unit of data in HoneyHive is called an event, which represents a span in a trace. A root event in a trace is of the type session, while all non-root events in a trace can be of 3 core types - model, tool and chain.

All events have a parent-child relationship, except session event, which being a root event does not have any parents.
  • session: A root event used to group together multiple model, tool, and chain events into a single trace. This is achieved by having a common session_id across all children.
  • model events: Used to track the execution of any LLM requests.
  • tool events: Used to track execution of any deterministic functions like requests to vector DBs, requests to an external API, regex parsing, document reranking, and more.
  • chain events: Used to group together multiple model and tool events into composable units that can be evaluated and monitored independently. Typical examples of chains include retrieval pipelines, post-processing pipelines, and more.

Here’s a visual representation of the event hierarchy:

​
Session Events

Session events are used to track the execution of your application. These can be used to capture

  • Session configuration like the application version, environment, etc.
  • Session metrics like session latency, session throughput, etc.
  • Session properties like user id, country, tier, etc.
  • Session feedback like overall session feedback, etc.

The Client Credentials Grant does not produce refresh tokens - you manually obtain new access tokens before the existing ones expire.\n\nAuthorization Code Grant\nThere are three parties involved in the Authorization Code flow -- the client (your application), the server (Ramp) and the user (data owner). The overall flow follows these steps:\n\nYour application sends the user to authenticate with Ramp.\nThe user sees the authorization prompt and approves the app's request for data access.\nThe user is redirected back via a redirect_uri with a temporary authorization_code.\nYour application exchanges the authorization_code for an access_token.\nRamp verifies the params and returns an access_token.\nYour application gets a new access_token with the refresh_token."

Model Events

Model events represent a request made to an LLM. These can be used to capture

  • Model configuration like model name, model hyperparameters, prompt template, etc.
  • Model metrics like completion token count, cost, tokens per second, etc.
  • API-level metrics like request latency, rate limit errors, etc.

Tool Events

When your LLM application interacts with external APIs, databases, or vector databases like Pinecone, you can instrument these interactions to evaluate performance, debug issues, and gain insights. Tool events are used to track the execution of anything other than the model. These can be used to capture

  • Tool configuration like vector index name, vector index hyperparameters, any internal tool configuration, etc.
  • Tool metrics like retrieved chunk similarity, internal tool response validation, etc.
  • API-level metrics like request latency, index errors, internal tool errors, etc.

​

See authorization guide for more information.\nScopes: Defines scopes that may be granted to access token.\nRedirect URIs: A list of URIs telling Ramp where to send back the users in the authorization process.\nRedirect URI format\nNote that redirect URIs must either use https protocol or be in localhost.\n\n✅ https://example.com/callback is valid\n❎ http://example.com/callback is invalid\n✅ http://localhost:8000/callback is valid\n\n\n\n\nOAuth 2.0\nRamp API uses the OAuth 2.0 protocol ↗ to handle authorization and access control.\n\nWhich grant type should you use?\nIf you are a Ramp customer and your application only accesses your own Ramp data, then you can use either client credentials grant or authorization code grant. If your application is used by other Ramp customers, the authorization code grant is required.\n\nClient Credentials Grant\nClient Credentials ↗ grant can be used to get an access token outside of the context of a user. It is typically used by applications to directly access their own resources, not on behalf of a user.\n\nTo obtain a token, make a request to POST /developer/v1/token. You must include an Authorization header containing a base-64 representation of client_id:client_secret.\n\n\nShell\n\nJavaScript\n\nPython\n\ncurl --location --request POST 'https://api.ramp.com/developer/v1/token' \\\n    --header 'Authorization: Basic <base64-encoded client_id:client_secret>' \\\n    --header 'Content-Type: application/x-www-form-urlencoded' \\\n    --data-urlencode 'grant_type=client_credentials' \\\n    --data-urlencode 'scope=business:read transactions:read' \nThe response JSON payload contains a ready-to-use access_token. The Client Credentials Grant does not produce refresh tokens - you manually obtain new access tokens before the existing ones expire.\n\nAuthorization Code Grant\nThere are three parties involved in the Authorization Code flow -- the client (your application), the server (Ramp) and the user (data owner). The overall flow follows these steps:\n\nYour application sends the user to authenticate with Ramp.\nThe user sees the authorization prompt and approves the app's request for data access.\nThe user is redirected back via a redirect_uri with a temporary authorization_code.\nYour application exchanges the authorization_code for an access_token.\nRamp verifies the params and returns an access_token.\nYour application gets a new access_token with the refresh_token."

Chain Events

Chain events help with categorizing the events into different stages of the pipeline. These can be synchronous or asynchronous stages.

How Chain Events Work

Any event that has its “parent” set to a chain event becomes a step within that chain. This simple mechanism allows you to consolidate various events into a single unit, making it easier to monitor the progress of your pipeline.

Nesting for Hierarchy

You can also nest chains within each other. This hierarchical approach lets you track the execution of your pipeline in a structured and organized manner. This nesting feature can be particularly useful for complex workflows.

Session Event as a Special Case: As a special case, the “session event” for a pipeline is essentially a chain event with all other events as its children. This means you can encapsulate the entire pipeline within a single session event, making it easy to manage and analyze.

By separating events into chains, you can track properties like:

  • Chain configuration like chain name, chain settings, etc.
  • Chain metrics like chain latency, chain throughput, etc.

Here’s an example chain event:
