Observability and Debugging OpenClaw on UBOS: Metrics, Tracing, Logging, and Alerting
# Observability and Debugging OpenClaw on UBOS
*Metrics, Tracing, Logging, and Alerting*
—
## Introduction
OpenClaw is a powerful, open‑source ticket‑management system that can be deployed on UBOS with just a few clicks. While the platform is feature‑rich, production operators quickly discover that visibility into the running service is essential for reliability and performance.
In this article we walk through a complete observability stack for OpenClaw on UBOS:
1. **Metrics** – Prometheus scrapes runtime metrics.
2. **Tracing** – OpenTelemetry captures request‑level traces.
3. **Dashboards** – Grafana visualises the data.
4. **Centralised Logging** – Fluent Bit / Loki aggregates logs.
5. **Alerting** – Prometheus Alertmanager notifies on anomalies.
All steps are designed to work out‑of‑the‑box with UBOS, leveraging the built‑in Agent and the UBOS Marketplace.

## 1. Exporting Metrics with Prometheus
### a. Enable the Prometheus Exporter
UBOS ships a **Prometheus Exporter** for any Docker container that exposes a `/metrics` endpoint. OpenClaw already includes the `prometheus-client` library, so you only need to expose the port:
yaml
services:
openclaw:
image: ubos/openclaw:latest
ports:
– “8080:8080”
– “9090:9090” # Prometheus metrics endpoint
environment:
– PROMETHEUS_ENABLED=true
### b. Configure the UBOS Prometheus Instance
The UBOS Agent automatically discovers services exposing `/metrics`. Add the following snippet to the UBOS **Prometheus** configuration (via the UBOS UI → *Monitoring* → *Prometheus*):
yaml
scrape_configs:
– job_name: “openclaw”
static_configs:
– targets: [“openclaw:9090”]
After saving, Prometheus will start pulling metrics such as `openclaw_requests_total`, `openclaw_response_time_seconds`, and `openclaw_db_connection_pool_size`.

## 2. Distributed Tracing with OpenTelemetry
### a. Install the OpenTelemetry Collector
Deploy the OpenTelemetry Collector as a side‑car or a separate container on the same UBOS host:
yaml
services:
otel-collector:
image: otel/opentelemetry-collector:latest
command: [“–config=/etc/otel-collector-config.yaml”]
volumes:
– ./otel-collector-config.yaml:/etc/otel-collector-config.yaml
ports:
– “4317:4317” # OTLP gRPC receiver
### b. Configure OpenClaw to Export Traces
Add the OTLP exporter to OpenClaw’s `application.yml`:
yaml
opentelemetry:
enabled: true
exporter:
otlp:
endpoint: “http://otel-collector:4317″
timeout: 10s
The collector forwards traces to a backend of your choice (Jaeger, Tempo, or the UBOS‑hosted Grafana Cloud). For a quick local view, enable the built‑in Jaeger UI in the collector config.

## 3. Visualising Data with Grafana Dashboards
UBOS includes a pre‑configured Grafana instance. Import the **OpenClaw Observability** dashboard (JSON ID `12345`) from the UBOS Marketplace, or create a custom one with the following panels:
| Panel | Metric | Description |
|——-|——–|————-|
| **Request Rate** | `rate(openclaw_requests_total[1m])` | Requests per second |
| **Latency** | `histogram_quantile(0.95, sum(rate(openclaw_response_time_seconds_bucket[5m])) by (le))` | 95th‑percentile response time |
| **DB Connections** | `openclaw_db_connection_pool_size` | Current size of the DB pool |
| **Error Rate** | `rate(openclaw_errors_total[1m])` | Errors per second |
| **Trace Count** | `otelcol_exporter_sent_spans_total{service.name=”openclaw”}` | Number of spans exported |
The dashboard can be set as the *home* view for the OpenClaw service in the UBOS UI.

## 4. Centralised Logging
### a. Fluent Bit → Loki
UBOS ships Fluent Bit as a log forwarder. Enable the Loki output in the Fluent Bit config:
ini
[OUTPUT]
Name loki
Match *
Host loki.ubos.tech
Port 3100
Labels {service=”openclaw”}
### b. Log Format
Configure OpenClaw to output JSON logs (e.g., via Logback):
xml
Now all logs appear in Grafana’s **Explore** view, searchable by `service=”openclaw”` and by fields such as `level`, `message`, and `trace_id`.

## 5. Alerting Rules
Create Prometheus alert rules in the UBOS **Alertmanager** UI:
yaml
groups:
– name: openclaw-alerts
rules:
– alert: HighErrorRate
expr: rate(openclaw_errors_total[5m]) > 0.05
for: 2m
labels:
severity: critical
annotations:
summary: “High error rate on OpenClaw”
description: “Error rate has exceeded 5% over the last 5 minutes.”
– alert: LatencySLOViolation
expr: histogram_quantile(0.95, sum(rate(openclaw_response_time_seconds_bucket[5m])) by (le)) > 2
for: 5m
labels:
severity: warning
annotations:
summary: “95th‑percentile latency > 2s”
description: “OpenClaw response latency is degrading.”
Configure Alertmanager to send notifications to Slack, email, or the UBOS mobile app.

## Conclusion
By wiring Prometheus, OpenTelemetry, Grafana, Loki, and Alertmanager together, you gain end‑to‑end observability for OpenClaw on UBOS. The stack provides real‑time metrics, distributed traces, searchable logs, and proactive alerts—allowing operators to detect and resolve issues before they impact users.
