}Statusline shows 0/0 containers even when containers are running
Verify Docker daemon is running with 'docker ps'. Check user has permissions to access Docker socket. On Linux, add user to docker group with 'sudo usermod -aG docker $USER' and restart terminal.
Colors not displaying correctly in statusline output
Ensure terminal supports ANSI color codes. Set TERM=xterm-256color in shell profile. Verify colorScheme setting in statusline.json matches terminal capabilities.
Statusline causing performance lag or high CPU usage
Increase refreshInterval to 3000-5000ms in configuration. Reduce docker ps query frequency. Consider caching container count between refresh cycles for better performance.
Health check status not updating or always showing healthy
Confirm containers have HEALTHCHECK defined in Dockerfile or docker-compose.yml. Verify docker version supports health checks (17.05+). Run 'docker inspect CONTAINER' to check health configuration.
