Viewing Logs¶

Logs play an important part in device monitoring. Reviewing logs regularly can help to identify and analyze issues early and ensure that things can run smoothly.

Logs in EnOS are categorized into two types as per the below.

Cloud Logs: Include upstream and downstream messages such as device onboarding, firmware upgrades, file uploads and downloads, data parsing, data reporting, data storage, commands,etc. Logs of upstream messages are messages sent by the device to the message queue, messages flowed from the topic queue to the rule engine, and messages forwarded from the rule engine to other products and services in EnOS Cloud, while logs of downstream messages are messages sent from the cloud to the device.
Device Logs: Include information that are related to the device running state and processing logic. Note that devices need to support log reporting for logs to be viewed.

This section shows how you can view logs of all devices under a product for the above two categories.
