agentmetrics-hermes

AgentMetrics observability plugin for Hermes agents. Auto-discovered via the hermes_agent.plugins entry-point — no code changes needed.

Install

pip install agentmetrics-hermes

Configuration

Create ~/.config/hermes/agentmetrics.yaml:

api_key: am_your_key
server_url: http://localhost:4000
agent_id: my-hermes-agent
environment: production

Or set environment variables (take precedence over the file):

Variable	Description
`AGENTMETRICS_API_KEY`	API key
`AGENTMETRICS_SERVER_URL`	Server URL
`AGENTMETRICS_AGENT_ID`	Agent identifier
`AGENTMETRICS_ENVIRONMENT`	Deployment environment

What gets tracked

Metric	Description
`input_tokens` / `output_tokens`	Aggregated LLM token usage
`cache_read_tokens` / `cache_write_tokens`	Prompt cache statistics
`estimated_cost_usd`	Computed from model pricing
`duration_ms`	Session wall-clock time
`tool_calls` / `tool_errors`	Per-step tool tracking
`llm_calls`	Number of model API requests
`secrets_blocked_count`	Credentials redacted before transmission
`error`	Exception message on failure (secrets scrubbed)

Durability

Events are written to a local WAL before transmission. If the server is unreachable the plugin retries automatically via an internal circuit breaker. Events that exhaust all retries go to a dead-letter queue and are surfaced as audit_dlq_alert events.

Security

All event payloads are scanned for API keys, JWTs, and passwords before transmission. Set redaction_mode: debug in the config to disable scrubbing during local development (expires automatically after a configurable TTL).
