Vigilmon vs Grafana Cloud: Simple Uptime Monitoring vs. Full Observability Stack
There's a question that comes up constantly when a development team outgrows their basic uptime monitor: "Should we just move everything into Grafana?"
It's a reasonable question. Grafana is everywhere. Your infrastructure metrics are probably already in it. The dashboards are already shared with the team. Grafana Cloud's Synthetic Monitoring seems like the natural next step — one less tool, one login, one bill.
Before you make that call, it's worth understanding what you're actually getting, what you're giving up, and which teams Grafana Synthetics is actually built for.
What Grafana Cloud Synthetic Monitoring Is
Grafana Cloud is the hosted version of the open-source Grafana observability stack — Grafana (dashboards), Loki (logs), Tempo (traces), and Mimir (metrics). It's a full LGTM stack in a managed SaaS, and for teams running complex distributed systems, it's genuinely powerful.
Grafana Synthetic Monitoring is a feature inside Grafana Cloud that lets you run:
- HTTP/HTTPS checks (status codes, response content, TLS validation)
- Multi-step API flows (scripted with k6)
- DNS checks
- Ping/ICMP checks
- TCP port checks
Checks are dispatched from a network of Grafana-managed probes and results flow into your Grafana dashboards alongside all your other metrics. The key phrase is alongside all your other metrics — Synthetic Monitoring is designed for teams already operating inside the Grafana ecosystem.
What Vigilmon Is
Vigilmon is a purpose-built uptime monitoring platform. It watches your HTTP endpoints, TCP ports, and SSL certificates, alerts you through Slack, email, or webhooks when something goes wrong, and provides a clean status page for your users.
Its defining feature is multi-region consensus: rather than a single probe declaring your site down after one failed check, Vigilmon requires checks from multiple geographic regions to agree before firing an alert. This eliminates an entire class of false positives — regional DNS hiccups, flapping CDN routes, transient probe failures — that haunt simpler uptime monitors.
No LGTM stack. No agents to deploy. No dashboards to configure before you get your first alert. You add a monitor, paste your Slack webhook, and you're done in under two minutes.
Feature Comparison
| Feature | Vigilmon | Grafana Cloud Synthetics |
|---|---|---|
| Multi-region consensus | Yes — quorum required before alerting | No — single probe per check location |
| HTTP/HTTPS monitoring | Yes | Yes |
| TCP monitoring | Yes | Yes |
| SSL certificate monitoring | Yes | Yes |
| DNS monitoring | Yes | Yes |
| Scripted multi-step checks | No | Yes (k6) |
| Status page | Yes, included | No (separate Grafana OnCall / Incident) |
| Slack / webhook alerts | Yes | Yes (via Grafana Alerting) |
| Free tier | Yes — 5 monitors, 1-min intervals | Yes — limited probe executions |
| Setup time | ~2 minutes | 30–60 minutes (Grafana Cloud onboarding) |
| Self-hostable | Yes (open source) | No |
| Requires existing Grafana stack | No | Strongly recommended |
| Pricing model | Flat / per-monitor | Usage-based (probe executions) |
The Stack Dependency Problem
This is the most important thing to understand about Grafana Synthetic Monitoring: it's not a standalone product.
To get useful alerts out of Grafana Synthetics, you need:
- A Grafana Cloud account with the Synthetic Monitoring plugin installed
- Alert rules configured in Grafana Alerting (separate from Synthetic Monitoring itself)
- A contact point set up (Slack, PagerDuty, email) via Grafana Alerting's notification policies
- Dashboards configured to actually surface the data you care about
None of these are hard steps, but they compound. A team that already lives in Grafana will complete this in an afternoon. A team that doesn't use Grafana for anything else will spend a week learning the alerting model, wrangling Loki log queries they don't need, and configuring dashboards before they get their first meaningful alert.
Vigilmon's onboarding is the inverse of this: add a URL, get alerted. The status page is included. Slack integration is two fields.
Pricing: What You Actually Pay
Grafana Cloud Pricing
Grafana Cloud's free tier includes:
- 10,000 Synthetic Monitoring execution credits/month
- Running an HTTP check every minute = ~43,200 executions/month per monitor
- Free tier covers roughly 0.2 monitors at 1-minute frequency
Once you exhaust the free execution credits, Synthetic Monitoring is billed at $1 per 1,000 executions. Monitoring 5 endpoints at 1-minute intervals costs roughly $215/month in execution credits alone — before you pay for any other Grafana Cloud resources.
The paid "Pro" tier at $299/month includes more resources across the full stack, which works out better if you're using Grafana for metrics and logs anyway. But if you're only here for uptime checks, $299/month is steep.
Vigilmon Pricing
| Tier | Cost | Monitors | Check Interval |
|---|---|---|---|
| Free | $0 | 5 managed / unlimited self-hosted | 1 minute |
| Pro | ~$10–20/month | More monitors | 30 seconds |
| Self-hosted | ~$5/month VPS | Unlimited | Configurable |
For pure uptime monitoring, Vigilmon's free tier gives you more effective monitoring coverage than Grafana Cloud's free tier by a significant margin.
The False-Positive Problem
Grafana Synthetic Monitoring dispatches checks from a selected probe location (or multiple if you configure them). Each location evaluates independently — one probe failing sends the alert.
This is the industry-standard single-probe model. And it's also why uptime monitoring alert fatigue is so common.
Vigilmon's multi-region consensus model requires a quorum of regional probes to agree on failure before alerting. A flaky probe in one region, a routing issue between two specific ASNs, a transient DNS failure in a single geography — none of these fire an alert. Only real outages that multiple independent vantage points agree on will wake your team.
For teams already dealing with alert fatigue inside a busy Grafana Alerting setup, adding more single-probe monitors to the pile is counterproductive. Vigilmon's signal-to-noise ratio is architecturally better.
When Grafana Cloud Synthetics Makes Sense
To be honest about the trade-offs: Grafana Synthetic Monitoring is excellent for specific teams.
Choose Grafana Cloud Synthetics if:
You're already paying for Grafana Cloud. If you have Grafana Pro or are paying for metrics/logs/traces, adding Synthetic Monitoring is marginal incremental cost and keeps your observability in one platform.
You need scripted multi-step check flows. Grafana's k6-based scripted checks let you simulate multi-page user journeys, authenticate via OAuth, verify checkout flows, or test APIs that require session state. Vigilmon doesn't do this.
Your team has a dedicated platform engineer. If someone owns Grafana configuration and alert routing, the setup overhead is manageable and the tight integration with infrastructure metrics is genuinely useful.
You want to correlate uptime with infrastructure metrics. Seeing a spike in CPU usage on the same dashboard as a synthetic check failure can speed root-cause analysis. Grafana's unified data model makes this possible.
When Vigilmon Makes Sense
Choose Vigilmon if:
You don't already use Grafana. The onboarding cost of Grafana Cloud for uptime monitoring alone doesn't make sense. Vigilmon is ready in two minutes.
You want fewer false alarms. Multi-region consensus is a material difference. If your team has learned to dismiss monitoring alerts, Vigilmon fixes the underlying problem.
Budget is a constraint. Vigilmon's free tier covers what most small teams need. Five monitors, one-minute intervals, status page, Slack alerts — $0/month, no credit card required.
You want a status page without extra setup. Grafana doesn't include a customer-facing status page — that's a separate product category. Vigilmon's status page is built in.
You want self-hostable, open-source infrastructure. Vigilmon runs on a standard Laravel stack and can be deployed on any $5 VPS. Grafana Cloud is SaaS-only.
Real-World Scenarios
Scenario 1: Solo developer, 2 production services
- Grafana Cloud: Free tier doesn't cover 2 monitors at 1-minute intervals. Requires Grafana Cloud account, plugin setup, alerting configuration. Overkill.
- Vigilmon: Free tier covers both monitors with room to spare. Two minutes to set up. Done.
Verdict: Vigilmon.
Scenario 2: 8-person team, already using Grafana Cloud for infrastructure metrics
- Grafana: Synthetic Monitoring integrates with existing dashboards. Alert routing already configured. Adding HTTP checks is additive.
- Vigilmon: Would be a separate tool with its own login and alerting config. Adds operational overhead.
Verdict: Grafana Synthetics, with the caveat to watch execution costs.
Scenario 3: Early-stage SaaS, 3 engineers, no existing observability stack
- Grafana: Starting from zero. Full onboarding, alerting configuration, dashboard setup. Considerable time investment before the first alert works reliably.
- Vigilmon: Zero prior setup required. Monitors running in 2 minutes. Status page live. Free.
Verdict: Vigilmon.
Conclusion
Grafana Cloud Synthetic Monitoring is a serious product for teams that are already invested in the Grafana observability ecosystem. If your team lives in Grafana dashboards and pays for the platform anyway, adding synthetic checks there is the right call.
But if your goal is simply to know when your site is down — accurately, with low noise, at a sane price — Grafana Synthetics is engineering overkill aimed at a different audience.
Vigilmon is purpose-built for that job. It starts faster, costs less, generates fewer false alarms (thanks to multi-region consensus), and includes a status page your customers can actually use. For developers who want uptime monitoring that gets out of the way, Vigilmon is the better fit.
