modbender OpenClaw Logfire Plugin
Pydantic Logfire observability plugin for OpenClaw. Traces the full agent lifecycle with OTEL GenAI semantic conventions — tool calls, token usage, errors, and optional distributed tracing across services.
Install
openclaw plugins install @ultrathink-solutions/openclaw-logfire
Set your Logfire write token:
export LOGFIRE_TOKEN="your-token"
Add to openclaw.json:
{
"plugins": {
"entries": {
"openclaw-logfire": {
"enabled": true,
"config": {}
}
}
}
}
Restart OpenClaw. Traces appear in your Logfire dashboard.
What It Traces
Every agent invocation produces a span tree:
invoke_agent chief-of-staff (root span)
|-- execute_tool Read (file read)
|-- execute_tool exec (shell command)
|-- execute_tool Write (file write)
Spans follow OTEL GenAI semantic conventions: gen_ai.agent.name, gen_ai.tool.name, gen_ai.usage.input_tokens, gen_ai.usage.output_tokens, etc.
Metrics
gen_ai.client.token.usage— token count histogram (input/output)gen_ai.client.operation.duration— agent invocation latency

Security & Privacy
- Secret redaction (on by default): Strips API keys, platform tokens, JWTs, and credentials from recorded tool arguments before export
- Tool output is not captured by default (
captureToolOutput: false) - Message content is not captured by default (
captureMessageContent: false) - Data destination: Traces are exported via OTLP HTTP to Pydantic Logfire (US or EU region). No other external endpoints are contacted.
- No local persistence: All data is streamed to Logfire; nothing is written to disk
