Inspecting the connection status of the Collector

Overview

For the whole Nexthink solution to work properly, it is essential that Collectors can communicate with their target Nexthink Appliances. To easily find out the status of the connection between a Collector and its assigned Nexthink Appliance, the Collector registers all connection attempts in the standard log of the underlying operating system.

  • The Windows Collector writes the messages to the Windows Event log.

  • The Mac Collector writes the messages to the system log.

Connection messages

When writing log messages to the Windows Event Log, the Windows Collector classifies the messages as Application logs and always tags them with the same source and task category:

Source

Nexthink Collector.

Task Category

Connection events.

Find below the complete list of messages and the other tags that the Collectors, both Windows and Mac, can write to the log. The parts of the message in cursive are replaced by actual data:
