observra 1.0.2

Framework-agnostic agent behavior analytics — CIM-based telemetry for AI agents

observra

Framework-agnostic agent behavior analytics.

Capture every meaningful agent action (token usage, tool calls, cost, errors) with structured context based on the Common Information Model (CIM).

Zero custom instrumentation per-agent. Answer "what happened, how much did it cost, and was it normal?" for any agent on any framework.

Install

pip install observra

With framework extras:

pip install observra[adk]           # Google ADK
pip install observra[claude]        # Claude Agent SDK
pip install observra[openai-agents] # OpenAI Agents SDK
pip install observra[langchain]     # LangChain / LangGraph
pip install observra[pydantic-ai]   # Pydantic AI

With backend extras:

pip install observra[otel]          # OTel span + log export

Install everything:

pip install observra[all]

Quick Start

import observra
from observra import log

observra.initialize(backend="jsonl", path="telemetry.jsonl")
log.session_start(agent_name="my-agent")
log.model_response("gpt-4o", input_tokens=500, output_tokens=200)
log.session_end(agent_name="my-agent")

Sample output (one line per event in telemetry.jsonl):

{"ts": "2025-01-15T10:23:45Z", "event_type": "model_response", "framework": "generic", "data": {"model": "gpt-4o", "in": 500, "out": 200, "cost_usd": 0.0035}}

Supported Frameworks

Framework	Install	Status	Captured Events
Google ADK	[adk]	Stable	LLM calls, tool calls, delegation depth, cost
Claude SDK	[claude]	Stable	Tool calls, model responses, session cost
OpenAI Agents SDK	[openai-agents]	Stable	Spans, tool calls, agent handoffs, cost
LangChain / LangGraph	[langchain]	Stable	Chain runs, tool calls, LLM calls, cost
Pydantic AI	[pydantic-ai]	Stable	Agent runs, tool calls, model calls

Backends

Backend	Install	Description
JSONL	(included)	Local JSON Lines file (default)
Webhook	(included)	Generic HTTP webhook POST delivery
Multi	(included)	Fan-out to multiple backends simultaneously
OTel Spans	[otel]	Export events as OTel spans via OTLP HTTP
OTel Logs	[otel]	Export events as OTel log records via OTLP HTTP

OTel Export (Dynatrace, Grafana, etc.)

from observra.backends.otel import OTelExportBackend
from observra.backends.otel_log import OTelLogBackend
from observra.backends.multi import MultiBackend

# Spans only
span_backend = OTelExportBackend(
    endpoint="https://your-collector/v1/traces",
    headers={"Authorization": "Api-Token ..."},
    service_name="my-agent-svc",
)

# Logs only
log_backend = OTelLogBackend(
    endpoint="https://your-collector/v1/logs",
    headers={"Authorization": "Api-Token ..."},
    service_name="my-agent-svc",
)

# Both spans and logs
backend = MultiBackend([span_backend, log_backend])

Key Features

• Cost tracking — per-session cost with model-specific pricing catalog and threshold alerts
• PII redaction — automatic secret/PII masking with configurable patterns
• Non-blocking — drop-oldest queue guarantees zero latency impact on the host agent
• CIM-normalized — structured events compatible with SIEM/analytics pipelines
• Safe regex — ReDoS-proof pattern matching via RE2 (optional: [safe-regex])
• Encryption at rest — AES field-level encryption for sensitive telemetry (optional: [encryption])
• Prompt injection detection — built-in heuristics for injection attempt classification
• Observability — get_metrics() / get_stats() for pipeline health introspection
• Deduplication — automatic event dedup across backends
• Session context — trace/span/session ID propagation with scoped contexts
