Server-side GTM monitoring that keeps tracking reliable.
Track the health and performance of server-side GTM applications, vendors, and event flows—so the system stays stable, available, and accurate.

Trusted by teams who care about data quality
Why monitoring matters
Server-side systems fail differently than browser tags.
Endpoint outages, tag failures, and misrouted traffic can silently degrade measurement quality. sGTM Monitor gives you early warning and clear signals when reliability slips.
What sGTM Monitor does
Clear focus, clear scope, and clear delivery—so stakeholders understand what gets checked and what to expect.
- The sGTM application remains stable and available
- Incoming and outgoing hits are processed without errors or data loss
- Latency and CPU usage stay within safe limits
- Data integrity between inbound and outbound events is safeguarded
By monitoring uptime, errors, latency, resource usage, and vendor calls, sGTM Monitor helps server-side tracking run smoothly.
- Uptime of the sGTM application
- Error rates and failed events
- Request latency and average response times
- CPU utilization and resource capacity
- Vendor event health (pixels, API calls, status codes)
- Inbound vs outbound payload differences
- Data consistency across parameters (Pixel ID, Event name, API token)
Alerts go directly to selected stakeholders (email or chat). Issues are reported in a dashboard for deep dives and trend insights.
- Requires no changes to your existing Server Side Google Tag Manager setup
- Monthly license based on number of servers (starting at €300 per server)
- Ongoing term with 3 months’ notice
Frequently asked questions
Quick answers for teams searching what sGTM means—and why monitoring belongs next to implementation.
What does sGTM mean?
sGTM means Server-Side Google Tag Manager. Tags run on a server you operate (often Google Cloud) instead of only in the visitor’s browser, so you control how events are received, transformed, and sent to vendors.
How is sGTM different from client-side GTM?
Client-side GTM fires tags in the browser. sGTM receives events on your server first, then forwards them. The browser can look healthy while server routing, latency, or vendor APIs fail quietly—which is why production monitoring matters.
Why do I need to monitor sGTM?
Uptime alone is not enough. Latency spikes, failed vendor dispatches, and dropped parameters can degrade measurement while the container still responds. Daily monitoring of availability, errors, latency, and payload integrity catches those silent failures early.
What does sGTM Monitor check?
sGTM Monitor tracks application uptime, error rates, request latency, CPU capacity, vendor event health (pixels, API calls, status codes), and inbound vs outbound payload differences—then alerts stakeholders by email or chat.
Do I still need data layer monitoring if I use sGTM?
Yes. sGTM can only forward what it receives. Incomplete or drifting client events still reach analytics and ad platforms. Many teams run Data Layer Monitor for event quality and sGTM Monitor for server delivery reliability together.
