View Agent Logs Using Commands

Admins can gather the JumpCloud Agent log manually or through the Admin Portal by downloading the logs under the Actions menu of the target device. However, it’s also possible to view the logs using Commands within JumpCloud. The following examples show how to read the Agent log on different operating systems.

Note:

Agent logs may exceed the 1MB size limitation of JumpCloud Commands, resulting in a truncated log. The following examples are designed to return the last 1MB (most recent portion) of the log if it exceeds that limitation.
