System status and information

Understanding real-time device status is the first step in routine maintenance. JelinaOS provides centralized status inspection and a visual cloud device dashboard.

View system versions

Use the system version command for complete version information:

jelina-ver --all

A single invocation returns the system version, kernel version, build information, and component metadata—essential information for troubleshooting and technical support.

Device status command

After logging in, use the integrated status command for a device overview:

jelina-info

The output includes:

• System information: System version, kernel version, and purpose (development/production).
• Device agent: Runtime status and version.
• Update status: Cloud connection status (Online), local update confirmation setting, and pending updates.
• Boot status: Current boot partition (A/B), boot target, and whether a reboot is required.
• System partitions: Currently running system and kernel partitions (A/B slots).

For scripts, use --get to query specific values:

jelina-info --get boot.reboot_required
jelina-info --get ota_status.status
jelina-info --get registration.status

Resource monitoring

Built-in resource monitoring tools provide process-level resource usage:

atop

• View CPU, memory, disk, and network usage in real time.
• Investigate abnormal application resource consumption.

Use the device information command for hardware details:

jelina-device-info            # Basic device information
jelina-device-info get -m1 -m2 --sn --ssn   # Identity information, including model and serial number

Operating mode and automatic recovery status

Use status commands to query key device operating states:

jelina-offline --state          # Offline-mode status
jelina-auto-recovery --state    # Automatic recovery status
jelina-info --get tmp_root --json       # Temporary root (space-recovery mode) status
jelina-info --get offline_mode --json   # Offline-mode details
jelina-info --get auto_recovery --json  # Automatic recovery details

Cloud device dashboard (recommended)

After connecting to JelinaCloud, open device details for a complete visual overview:

Information	Description
Device status	Online status, system and agent versions
Runtime overview	Resource usage, operating temperature, storage usage
Application status	Runtime status of container and program services
Runtime logs	Device logs retained in the cloud for later investigation

Quick diagnostic workflow

When a device behaves abnormally, collect information in this order:

1. Run jelina-info to check system version and health.
2. Review the cloud dashboard for resource usage and alerts.
3. Check relevant service status; see services and processes.
4. Provide the system version, serial number, and logs when contacting Advantech technical support.
