The logs functionality is very important to gain insight into what happens in a qbee controlled system. Most (but not all) configuration changes will create a log entry and thus allow to follow what is happening. There are 4 different levels of log entries. Usually only critical and error messages need attention, while warning and info messages just flag events. This gives you the necessary insight into the device automation aspect of this solution.

  • Info:
    Basic information about events that have happened. No action needed.

  • Warning:
    Information that has impacted the device but usually no action needed. A typical example is the restart of an application.

  • Error:
    This an indication that something has not happened the way it was intended to. This is a status message that usually demands action.

  • Critical:
    Here immediate action is needed as something is critically wrong and needs fixing.

A typical info message can be an information about a successfully downloaded config file template:


A warning could be the message that a process had to be restarted (in this case because a config file had to be reloaded due to changes):



Most configuration events create a log file entry. Setting changes will not be visible in the log but in the audit trail.

Critical and error messages

Critical and error messages usually mandate additional investigation. Maybe a file path was incorrect, a service was not existing or it was in general not possible for the qbee agent to converge to the desired state of the configuration. This could be wrong permissions or any other of the myriad reasons Linux does not behave as expected. Please find the root cause and correct this.

Warning and info messages

Warning messages often contain valuable information but the system continues to operate without problems. A typical warning could be a process that was restarted to activate new configuration or a connectivity watchdog that triggered.

The main log page looks as follows:


It is possible to filter the logs by any time range. The default time range is 24h. The select labels function allows to filter for which events you search for. In the example below "software_management", password and NTP is selected.


Additional search options are for host name, message content, commit ID and which log level severity should be shown. In the example below only critical events are selected.


There is a function that allows to mark log entries as read. This may help to track down critical or error logs.

Group log messages

By checking the "group results" box you will group all repeating log messages. If you miss messages make sure that you have not deselected any of the warning levels such as "info".
