At Golioth, we believe that the ability to perform Over-The-Air (OTA) updates is a crucial part of any IoT product, as it not only lets manufacturers upgrade their products in the field, but also provides an extra safety net that lets them recover from any unforeseen software issues. Because OTA updates are the safety net, the importance of control and overview is even higher in the update mechanism than any other aspect of the product. A few months ago, we introduced Cohorts as a new way of managing OTA updates for devices connected to Golioth. Cohorts provided a safer user experience for OTA by explicitly grouping devices that were receiving the same OTA updates into cohorts and presenting the update history for each cohort separately. Introducing the OTA Event Log Since the release of Cohorts, we have been working on improving your ability to observe the OTA update process, and we’re excited to reveal our first OTA observability improvement: The OTA Event Log. The OTA Event Log is a timeline of events recorded in a cohort. The event log is a available in a new tab in the cohort management page, and is presented as an interactive timeline with an accompanying log of events. The timeline view contains an hourly summary of the reported events in the last week, as well as markers for any deployments to the cohort. The OTA Events are based on the OTA state reports that are reported by the device as it moves through the update process. These are the same reports that power the firmware status tab of the device management page, but with the new timeline view, you’ll be able to review the…
