Stop guessing. Start observing.
Real-time telemetry and log streaming from every device in your fleet — including the constrained ones. Memory, CPU, reboot tracking, structured logs, and fleet-wide analytics.
When something goes wrong in the field, you're flying blind
Embedded devices don't get the luxury of kubectl describe pod. When something goes wrong, you're guessing from customer reports, shipping replacement units, or begging someone on-site to plug in a UART cable.
Koios gives you the observability stack your embedded devices have been missing. Real-time and historical telemetry from every device — even those running on a few kilobytes of RAM.
See What Your RTOS Sees
Memory, CPU, reboots, and custom metrics from every device in your fleet.
Track free heap, high-water marks, heap fragmentation, and stack usage per task. Monitor CPU utilization, peripheral bus errors, watchdog resets, and brownout events. Classify reboot reasons and track frequency over time. Define custom application-specific metrics — sensor readings, protocol error rates, connection retry counts.
- Memory & heap telemetry
- CPU & peripheral monitoring
- Reboot classification & tracking
- Custom application metrics
- Fleet-wide aggregation
- Threshold & anomaly alerting
Structured Logs from Constrained Devices
Tail logs in real time. Search across your entire fleet. Query on any field.
Stream structured logs from devices with kilobytes of RAM. Full-text search across all device logs — find the needle in the haystack across thousands of devices. Every log entry is automatically tagged with device ID, firmware version, device group, and timestamp. Cross-reference log spikes with firmware deployments, certificate rotations, or configuration changes.
- Real-time log streaming
- Full-text search
- Structured key-value logging
- Deployment correlation
- Automatic context tagging
- Configurable retention policies
Designed for Microcontrollers, Not Linux Servers
Runs in kilobytes, not megabytes. Because every byte matters on constrained devices.
The Koios telemetry and logging agent is built for constrained devices. Minimal RAM footprint. Configurable reporting intervals. Batched uploads over the same mTLS channel your device already uses — no additional attack surface, no extra connection overhead. On a device with 64KB of RAM, every byte of your monitoring agent is a byte your application can't use.
- Minimal RAM footprint
- Configurable reporting intervals
- Batched mTLS uploads
- No additional attack surface
Did Memory Usage Spike After v2.3.1?
Correlate metric changes with firmware deployments. See cause and effect across your fleet.
Koios automatically associates telemetry and log data with device identity, firmware version, and device group. Cross-reference log spikes with certificate rotations. Spot trends before they become incidents. Identify a memory leak affecting 3% of your fleet before a single customer reports an issue.
- Firmware version correlation
- Device group analytics
- Trend detection
- Proactive incident prevention
Capabilities
Everything you need to understand what your devices are doing in the field.
Security isn't a feature. It's the architecture.
Built on infrastructure you already trust. Every byte encrypted at rest and in transit. Keys stored in dedicated HSMs. We don't sell your data. Full stop.
AES-256 at Rest
All data encrypted in storage
mTLS in Transit
Mutual authentication on every connection
HSM Key Storage
Keys never exist in plaintext
SOC 2 In Progress
Type II audit underway
