Troubleshoot Common Problems
Some of the common problems you might encounter are:
A host is not showing up in the user interface.
The agent log file shows “Error, connection_manager: Lost connection” messages.
Suspect agent connectivity problems and troubleshoot for those. Inspect the agent log file is located at
Perform the following checks and see if it solves your problem:
Confirm that you have not used all available agent licenses.
The agent license count is available in the Settings > Subscription tab. Administrators can purchase additional agent licenses using the UI if needed.
Confirm basic connectivity through your firewall:
Confirm the correct port is open through your firewall:
telnet collector.sysdigcloud.com 6443
In earlier versions, the Sysdig Agent connected to port 6666. This behavior has been deprecated, as the Sysdig Agent now connects to port 6443.
Check MAC Addresses
Check for duplicate MAC addresses in your hosts.
When the agent starts, an entry in the
/opt/draios/logs/draios.log file reports the host’s MAC:
2016-09-26 10:20:25.982, 2363, Information, machine id: a2:11:0b:84:11:21
Compare the logged MAC address to any existing reporting agents in the
Explore tab using the
Hosts & Containers hierarchy.
Check Access Key
See Settings > Agent Install for the access key and confirm that it is correct.
The Sysdig Agent key is configured in the agent configuration file,
opt/draios/etc/dragent.yaml. See Understanding the Agent
Config Files for more information.
Upgrade the Sysdig Agent
