Output of “cmk --debug -vvn hostname”: (If it is a problem with checks or plugins)
Good morning everyone.
This query is for you to help me, install checkmk under docker, but at the moment, but I install the checkmk agent on another promox server to monitor it but it does not recognize the agent, it already has the user for the special agent, it communicates but still without recognize it and identify services.
In proxmox I already opened ports 6556.
When testing the connection I get the following message.
Communication failed: timed outAgent exited with code 1: Caught unhandled ConnectionError(HTTPSConnectionPool(host=‘xxxx’, port=8006): Max retries exceeded with url: /api2/json/access/ticket (Caused by NewConnectionError(‘<urllib3. connection.HTTPSConnection object at 0x7f9fdd1d8970>: Failed to establish a new connection: [Errno -2] Name or service not known’))) in /omd/sites/cmk/lib/python3/cmk/special_agents/utils/agent_common.py :135

Why is there no communication with the agent?
I also disabled the fw to see if that was the problem, but it persists.
The error message only says that CMK cannot reach the port of the Proxmox API/HTTPS management.
I don’t see that it gives a error message about the normal agent.
Can you please show how the host is configured inside CMK?
You need to look for the output of “cmk -D hostname”
It should look like this for your Proxmox host.

In your first post you said you want to monitor a Proxmox host with agent and special agent.
The shown output in the last post shows an docker container.
I cannot follow what exactly you want to do.
Hi Andreas, reinstall checkmk. but persist the problem.
Install checkmk on site, nothing docker.

In the checkmk server have install the agent?.
In my host run cmk-agent-ctl pull
output
ERROR [cmk_agent_ctl] Failed to listen on TCP socket for incoming pull connections.
I think it will be because I want to monitor servers that are in other countries, that’s why it won’t let me, is there a way to establish that from my checkmk server it communicates through ssh with the agent of the other server that I want to monitor?
All outputs shown make no sense.
Please show the command you use to get the output.
I will try again from the start.
In your first post you want to monitor a Proxmox host with agent and special agent together.
Yes or No?
If yes please do a “cmk -D name_of_the_proxmox_host” on the command line and please show the command and output (user, password and so on can be removed).
Yes, you can use ssh to connect to some host and run the agent there. You should be able to find some discussion on that topic here in the forum. Surprise, there’s even a chapter in the official documentation for exactly that feature (section “6. Encrypted: Use of an SSH tunnel”):
