For the first three months of running OpenClaw, my monitoring strategy was: check the terminal every few hours and hope nothing was on fire. Spoiler: things were occasionally on fire, and I didn’t know until someone told me.
Then I set up a Grafana dashboard, and it was like putting on glasses for the first time. Suddenly I could see everything — response times, token usage, error rates, agent activity — all in one place, in real-time, with pretty graphs that make me feel like I’m running a spaceship.
Here’s how I built it, what I track, and why it matters more than you think.
Why Bother With a Dashboard
“Logging is enough” is what I told myself before the dashboard. It’s not enough. Logs tell you what happened after someone complains. A dashboard tells you what’s happening before anyone notices.
Three things my dashboard caught that logs alone wouldn’t have:
Gradual response time degradation. Over two weeks, average response time crept from 2.3 seconds to 4.8 seconds. The increase was too gradual to notice in individual interactions, but the trend line on the dashboard was obviously wrong. Root cause: a growing conversation context that wasn’t being pruned.
Token cost spike. One Tuesday, my daily token usage jumped 3x. Not because of more requests — because of longer responses. A prompt change I’d made the previous day was causing the model to generate much more verbose outputs than intended. The dashboard caught it within hours; otherwise, I would’ve noticed when the monthly bill arrived.
Silent cron job failures. Two scheduled jobs had been failing silently for a week. The dashboard showed the expected pattern (daily execution spikes at specific times) had gaps. Without the visual pattern, I might not have noticed for another week.
The Setup
Stack: Prometheus for metrics collection, Grafana for visualization, Node Exporter for system metrics. Total setup time: about 3 hours. Total cost: free (self-hosted) or $15/month (Grafana Cloud free tier covers most needs).
If you’re already running a VPS for OpenClaw, you can run Grafana on the same server. My setup runs Prometheus and Grafana on the same $20/month VPS as OpenClaw, with no noticeable performance impact.
Getting metrics out of OpenClaw: OpenClaw logs are the primary data source. I wrote a simple script that parses log files and exposes metrics as a Prometheus endpoint. The key metrics to extract:
– Request count (total and per-type)
– Response time (average, p95, p99)
– Token usage (input and output, per request)
– Error count (by type)
– Active sessions
– Cron job execution status
My Dashboard Layout
I have four rows:
Row 1: Health at a glance. Four big numbers: current response time, requests in the last hour, error rate, and estimated daily cost. Green when normal, yellow when elevated, red when something needs attention. I look at this row 10 times a day.
Row 2: Trends. Time-series graphs for response time, request volume, and token usage over the past 24 hours and 7 days. This is where I spot gradual degradation and unusual patterns.
Row 3: Costs. Token usage broken down by model, by task type, and by hour. A daily running total compared to budget. This row has saved me hundreds of dollars by catching cost anomalies early.
Row 4: Agent activity. Which agents are active, what they’re working on, cron job execution history, and recent errors with details. This is the debugging row — I only look at it when something’s wrong.
The Alerts That Actually Matter
I set up 6 alerts. After a month of tuning, I removed 2 that were too noisy and adjusted the thresholds on the remaining 4.
Alert 1: Response time > 10 seconds. This fires when the p95 response time exceeds 10 seconds over a 5-minute window. Usually means the AI API is having issues, or my context is too large.
Alert 2: Error rate > 5%. More than 5% of requests failing means something is systematically wrong, not just occasional API hiccups.
Alert 3: Daily cost exceeds 2x average. Catches runaway loops and unexpected usage spikes before they become expensive.
Alert 4: Cron job missed execution. If an expected cron job doesn’t run within 30 minutes of its scheduled time, something’s wrong.
These four alerts are the right balance for my setup. Enough to catch real problems. Not so many that I start ignoring them.
What I’d Skip
Per-request dashboards. I initially built a panel showing every individual request. It was interesting for about a day, then became noise. Aggregate metrics are more useful than individual data points for monitoring.
Model comparison panels. I built panels comparing Claude vs GPT-4o quality scores. The data was interesting but not actionable — I’d already decided which model to use, and the dashboard didn’t change that decision.
Fancy visualizations. Grafana can make beautiful dashboards with gauges, heatmaps, and flow diagrams. Resist the urge. Simple line charts and big numbers are more readable at a glance, which is the whole point.
The ROI Calculation
Setup time: 3 hours.
Monthly maintenance: 30 minutes (updating dashboards, tuning alerts).
Savings from catching issues early: estimated $200-300/month in prevented cost overruns and reduced downtime.
The dashboard paid for itself in the first month. If you’re running OpenClaw (or any AI system) without observability, you’re flying blind. You might be flying fine. But when you’re not, you won’t know until you’ve already crashed.
