ERROR [cmk_agent_ctl] Error while loading registered connections

Troubleshooting
1

One of my hosts is producing this error, while most others register fine:

root@sshgateway:~# cmk-agent-ctl register --hostname gateway.gerhards.local --server 10.0.4.107:8000 --site home -U cmkadmin
ERROR [cmk_agent_ctl] Error while loading registered connections.

Caused by:
    EOF while parsing a string at line 8 column 1040
Cmk-agent-ctl register: Failed to discover agent receiver port

You can add -vv to this command for more verbosity.

Adding -vv gives one line more, which says basically nothing…


root@sshgateway:~# cmk-agent-ctl register --hostname gateway.gerhards.local --server 10.0.4.107:8000 --site home -U cmkadmin -vv 
INFO [cmk_agent_ctl] starting
ERROR [cmk_agent_ctl] Error while loading registered connections.

I would say remove the agent and then make sure that ~/var/lib/check_mk_agent is deleted and then re-install it again.

The path you might be looking for is /var/lib/cmk-agent/.
There lives /var/lib/cmk-agent/registered_connections.json, which stores the registered connections. It might have been corrupted.

Hey, like @davidwayne wrote, removing var lib with: rm -rf /var/lib/cmk-agent/ fixed the ERROR [cmk_agent_ctl] Error while loading registered connections.
Here is what I noticed: the disk (/) ran full during executing this command. I enlarged it and it worked.

Hi @peterge, please open dedicated threads for distinct problems, so it is easier for others to find.
Also, please mark correct answers as the solution (I took the liberty to do so already :slight_smile:).
