Comprehensive Observability for OpenClaw on UBOS: Metrics, Tracing, Logging, and Alerting
Why Observability Matters for Operators
In modern micro‑service environments, operators need real‑time insight into the health, performance, and behavior of their applications. Observability—comprising metrics, tracing, and logging—provides the data needed to detect issues, understand root causes, and ensure reliable service delivery.
Step‑by‑Step Guide
1. Prometheus Metrics
# prometheus.yml
scrape_configs:
- job_name: 'openclaw'
static_configs:
- targets: ['localhost:9090']
Deploy the Prometheus server on UBOS and configure OpenClaw to expose metrics at /metrics. Use the prometheus_client library in your OpenClaw code to register custom counters, gauges, and histograms.
2. OpenTelemetry Tracing
# Install OpenTelemetry SDK
pip install opentelemetry-sdk opentelemetry-exporter-otlp
# Initialize tracer in OpenClaw
from opentelemetry import trace
from opentelemetry.sdk.trace import TracerProvider
from opentelemetry.sdk.trace.export import BatchSpanProcessor
from opentelemetry.exporter.otlp.proto.grpc.trace_exporter import OTLPSpanExporter
trace.set_tracer_provider(TracerProvider())
tracer = trace.get_tracer(__name__)
otlp_exporter = OTLPSpanExporter(endpoint="http://localhost:4317")
trace.get_tracer_provider().add_span_processor(BatchSpanProcessor(otlp_exporter))
Configure the OpenTelemetry Collector on UBOS to receive spans and forward them to a backend such as Jaeger or Tempo.
3. Centralized Logging with Loki
# loki-config.yaml
auth_enabled: false
server:
http_listen_port: 3100
# Promtail configuration (runs on each node)
clients:
- url: http://localhost:3100/loki/api/v1/push
scrape_configs:
- job_name: system
static_configs:
- targets:
- localhost
labels:
job: varlogs
__path__: /var/log/**/*.log
Update OpenClaw to write logs in JSON format so Loki can parse fields automatically.
4. Alerting Rules
# alerts.yml
groups:
- name: openclaw-alerts
rules:
- alert: HighRequestLatency
expr: histogram_quantile(0.95, sum(rate(http_request_duration_seconds_bucket[5m])) by (le)) > 0.5
for: 2m
labels:
severity: critical
annotations:
summary: "High request latency detected"
description: "95th percentile latency > 0.5s for more than 2 minutes."
Load this file into Prometheus and configure Alertmanager to send notifications to Slack, email, or PagerDuty.
Deployment Checklist
- Provision UBOS instance and install Docker.
- Deploy Prometheus with
prometheus.ymlandalerts.yml. - Deploy OpenTelemetry Collector and configure OTLP receiver.
- Deploy Loki and Promtail agents on each node.
- Update OpenClaw service to expose
/metricsand emit OpenTelemetry spans. - Verify metrics in Prometheus UI, traces in Jaeger/Tempo, and logs in Grafana Loki.
- Test alerting by inducing latency or error conditions.
- Document the setup and add monitoring dashboards.
For a production‑ready deployment of OpenClaw on UBOS, see the hosting guide: Host OpenClaw on UBOS.
With these components in place, operators gain full visibility into OpenClaw’s behavior, enabling rapid troubleshooting and proactive reliability.
