| - | ===== Agent Types ===== | ||
| - | |||
| - | ^ Type ^ Use When ^ | ||
| - | | TLS | Host supports cmk-agent-ctl-daemon | | ||
| - | | Legacy | Unprivileged LXC containers | | ||

| - | ===== Current Hosts ===== | ||
| - | |||
| - | ^ Host ^ Type ^ Notes ^ | ||
| - | | traefik (CT 102) | TLS | nesting=1 required | | ||
| - | | hv-04 (Proxmox) | TLS | Native host | | ||
| - | | openclaw (CT 103) | TLS | UFW port 6556 | | ||
| - | | postgres (CT 110) | Legacy | TCP 6556 | | ||

| - | ===== Adding a New Host ===== | ||
| - | |||
| - | ==== 1. Install Agent ==== | ||
| - | |||
| - | <code bash> | ||
| - | # Get agent package from Checkmk | ||
| - | scp [email protected]:/ | ||
| - | |||
| - | # Install | ||
| - | dpkg -i / | ||
| - | </ | ||
| - | |||
| - | ==== 2a. TLS Mode (if daemon works) ==== | ||
| - | |||
| - | <code bash> | ||
| - | cmk-agent-ctl register \ | ||
| - | --hostname < | ||
| - | --server 10.100.161.115 \ | ||
| - | --site monitoring \ | ||
| - | --user cmkadmin \ | ||
| - | --password < | ||
| - | --trust-cert | ||
| - | </ | ||
| - | |||
| - | ==== 2b. Legacy Mode (unprivileged LXC) ==== | ||
| - | |||
| - | <code bash> | ||
| - | # Delete TLS registration | ||
| - | cmk-agent-ctl delete-all --enable-insecure-connections | ||
| - | |||
| - | # Enable TCP socket | ||
| - | mkdir -p / | ||
| - | cat > / | ||
| - | [Socket] | ||
| - | ListenStream= | ||
| - | ListenStream=6556 | ||
| - | EOF | ||
| - | |||
| - | systemctl daemon-reload | ||
| - | systemctl restart check-mk-agent.socket | ||
| - | |||
| - | # Disable broken daemon | ||
| - | systemctl disable --now cmk-agent-ctl-daemon | ||
| - | </ | ||
| - | |||
| - | ==== 3. Add Host in Checkmk ==== | ||
| - | |||
| - | <code bash> | ||
| - | # Via CLI | ||
| - | pct exec 115 -- su - monitoring -c "cmk -II < | ||
| - | |||
| - | # Or via Web UI: Setup > Hosts > Add host | ||
| - | </ | ||
| - | |||
| - | ===== Troubleshooting ===== | ||
| - | |||
| - | <code bash> | ||
| - | # Test agent from Checkmk | ||
| - | pct exec 115 -- su - monitoring -c "cmk -d < | ||
| - | |||
| - | # Test TCP connectivity | ||
| - | nc -v < | ||
