Automating Alerts on K6 Synthetic Trace Data for the OpenClaw Rating API Edge

Automating Alerts on K6 Synthetic Trace Data for the OpenClaw Rating API Edge

After the visibility‑only guide, the next logical step for developers is to turn that visibility into actionable alerts. This article walks you through configuring K6 to emit OpenTelemetry traces, routing them to a collector, creating Prometheus/Alertmanager rules, and integrating the alerts with UBOS‑hosted OpenClaw deployments. The guide is framed within the current AI‑agent hype, showing how automated observability can power intelligent agents in the OpenClaw ecosystem.

1. Configure K6 to Emit OpenTelemetry Traces

1. Install the OpenTelemetry exporter for K6:

   npm install -g @k6io/opentelemetry

2. Add the exporter to your K6 script:

   import { trace } from "k6/opentelemetry";
   export const options = {
     stages: [{ duration: "30s", target: 10 }],
     ext: {
       otel: {
         endpoint: "http://localhost:4317",
         serviceName: "k6-openclaw-test"
       }
     }
   };
   
   export default function () {
     // your API calls to OpenClaw Rating API Edge
     trace.startSpan("ratingRequest");
     // ... request logic ...
     trace.endSpan();
   }
   

2. Route Traces to a Collector

Deploy the OpenTelemetry Collector (OTELCOL) on your UBOS cluster. A minimal collector-config.yaml:

receivers:
  otlp:
    protocols:
      grpc:
        endpoint: 0.0.0.0:4317
exporters:
  prometheus:
    endpoint: "0.0.0.0:9464"
service:
  pipelines:
    traces:
      receivers: [otlp]
      exporters: []
    metrics:
      receivers: []
      exporters: [prometheus]

Apply it with kubectl apply -f collector-config.yaml. The collector will expose metrics at /metrics which Prometheus can scrape.

3. Create Prometheus Rules for Synthetic Trace Alerts

Define a rule that fires when the latency of the ratingRequest span exceeds a threshold:

groups:
- name: k6-synthetic-alerts
  rules:
  - alert: K6HighLatency
    expr: histogram_quantile(0.95, sum(rate(opentelemetry_span_duration_seconds_bucket{service_name="k6-openclaw-test", span_name="ratingRequest"}[5m])) by (le)) > 2
    for: 2m
    labels:
      severity: critical
    annotations:
      summary: "High latency detected in OpenClaw Rating API Edge synthetic test"
      description: "95th percentile latency > 2s for the last 5 minutes."

Load this rule into Prometheus (e.g., via a ConfigMap) and reload.

4. Configure Alertmanager to Route Alerts

In alertmanager.yml add a receiver that posts to a UBOS webhook or Slack:

receivers:
- name: "ubos-webhook"
  webhook_configs:
  - url: "https://ubos.tech/api/alerts"
    send_resolved: true

route:
  receiver: "ubos-webhook"
  group_wait: 30s
  group_interval: 5m
  repeat_interval: 4h

5. Integrate Alerts with UBOS‑hosted OpenClaw Deployments

UBOS can automatically scale or restart OpenClaw services based on incoming alerts. Create a small automation script (or use an AI‑agent) that listens to the webhook payload and triggers UBOS CLI commands, e.g.:

#!/bin/bash
# payload contains alert name and severity
if [[ "$ALERT_NAME" == "K6HighLatency" ]]; then
  ubos service restart openclaw-rating-api
fi

Deploy this script as a Kubernetes Job or a serverless function within the UBOS ecosystem.

6. Final Thoughts

This guide transforms raw synthetic trace data into proactive alerts, closing the loop between observability and operational response. By embedding the alerting workflow into UBOS‑hosted OpenClaw deployments, developers can maintain high reliability while leveraging the buzz around AI‑agents that react to real‑time signals.
