Overlock

Overlock allows you to discover exceptions and faults in your IoT system. Overlock gathers together exception information from all areas of your IoT deployment, whether it’s on end devices, gateways or servers. You simply add exception handlers and start benefiting from:

1. Bread crumbs, state and exception data to help you get to the root cause of problems fast
2. Reduce data transfer with intelligent logging. Data is only uploaded when it’s relevant
3. Device timeline views which show the lifecycle of your device to aid with debugging
