Essential IoT connectivity KPIs
Uptime / Availability (%)
The single most important measure: how often devices maintain an active, usable connection. A high availability score underpins service level agreements (SLAs) and keeps operations running smoothly. Even small drops in uptime can mean lost revenue or critical service interruptions.
Latency (ms)
Latency measures how quickly data travels between device and destination. For use cases like EV charging, telematics, or smart grid management, low latency is critical. Anything above target thresholds can break user experience or, in safety-critical systems, create real risks.
Data Usage Efficiency
Are your devices transmitting useful data, or wasting bandwidth with unnecessary chatter, retries, or even security breaches? Measuring efficiency helps you spot misconfigurations, optimise data pooling, and avoid overspending on connectivity.
Connection Success Rate (%)
Every failed attach attempt adds friction. Monitoring first-time connection success rates shows whether devices are onboarding smoothly to the network, or whether roaming agreements, coverage gaps, or SIM issues are creating hidden costs.
Mean Time to Resolve (MTTR)
When something goes wrong, speed matters. MTTR measures how long it takes to restore connectivity once an issue is flagged. The shorter the MTTR, the less downtime for your services, and the more confidence your customers have in your reliability.
Roaming Performance Metrics
For IoT fleets spanning multiple countries, monitoring roaming success rates, handover times, and latency is key. Poor roaming performance creates silent failures in the field, leaving devices offline without warning.
Why these KPIs matter
- Operational reliability – High uptime and low latency underpin everything from SLAs to end-user trust.
- Cost control – Data efficiency and connection success rates prevent overages and wasted spend, and support accurate capacity planning.
- User experience – Smooth, fast, and stable connections improve the performance of connected applications and services.
- Scalability – Tracking KPIs at scale helps teams anticipate bottlenecks and plan for fleet growth without service degradation.
- Security and compliance – Inefficiencies or anomalies in KPIs can flag suspicious activity early, helping you prevent breaches or compliance failures.
