The ARP Host tab displays the status of the ARP host system connected to an SC//AcuVigil™ VG edge security device (ESD) on VGMv1 hardware. The ARP host is a separate Linux server — not the ESD itself — that runs containerized applications and virtual machines managed by the SC//AcuVigil platform. Use this tab to monitor the host's memory, interfaces, containers, disk partitions, and KVM virtual machines.
Application description: Status of ARP host system
Supported ESD models: VG (VGMv1 hardware variant only). VGMv1 and VGLv1 are the two hardware variants of the VG.
Layout
The ARP Host tab has a standard app header and a single combined view. There are no sub-navigation links. All sections are displayed together in a single scrolling view.
Header
| Element | Description |
|---|---|
| App icon | ARP Host app icon. Decorative. |
| ARP Host | App name / block title. |
| Subtitle | "Status of ARP host system". Static descriptor. |
Host status section
Summary-level health metrics for the host system.
| Field | Units | Description |
|---|---|---|
| Node Name | Text | The hostname of the ARP host server (for example, store101-pos1). |
| Free memory | GiB | Available RAM not currently in use by the OS or running containers and VMs. |
| Total memory | GiB | Total physical RAM installed in the host server. |
| Memory Capacity | % | Current memory utilization: (Total - Free) / Total. |
| Host uptime | Days | Number of days since the host was last rebooted. |
| Timestamp | Date/time | Time this status report was generated, in Day Mon DD HH:MM:SS TZ YYYY format. |
Host information section
Hardware and operating system details for the ARP host.
| Field | Description |
|---|---|
| CPU | Processor model name (for example, Intel Atom(R) C5325 processor). |
| OS | Operating system distribution (for example, Debian). |
| OS Release | OS version number (for example, 12.9). |
| Kernel | Linux kernel version string (for example, 6.1.0-31-amd64). |
| BIOS Release Date | Date the system BIOS firmware was released (format: MM/DD/YYYY). |
| BIOS vendor | BIOS manufacturer (for example, American Megatrends International, LLC.). |
| BIOS Version | BIOS firmware version string (for example, 1.5). |
| Board Serial Number | Motherboard serial number (for example, 0000000000AA). |
| Serial Number | System-level serial number (for example, 0000000000AB). |
Interface status section
Network interface status for every interface on the ARP host, including physical, virtual, and bridge interfaces.
| Column | Description |
|---|---|
| Interface | OS-level interface name (for example, eno4, br0, docker0, tun0). |
| MTU | Maximum Transmission Unit in bytes (for example, 1500, 9000, 65536). Jumbo frames (9000) indicate high-throughput links. 65536 is the loopback MTU. |
| Link Status | Layer-1 link state: up, down, or unknown. |
| Type | Interface type: physical (real NIC) or virtual (bridge, tunnel, container network, or loopback). |
| MAC Address | Hardware MAC address of the interface, if assigned. Empty for some virtual interfaces. |
| IP Address | IPv4 address assigned to the interface. Empty if no IP is configured. |
Interface types
| Interface pattern | Type | Purpose |
|---|---|---|
eno* |
physical | Physical Ethernet ports. |
br* |
virtual | Linux bridge interfaces (used by container and VM networking). |
lo |
virtual | Loopback interface. Its MTU of 65536 is normal. |
Other virtual interfaces, such as container networks or tunnels, can also appear.
Container status section
Status of Docker containers running on the ARP host.
| Column | Description |
|---|---|
| Name | Container name as defined in the Docker deployment configuration. |
| Size | Container layer size on disk, with virtual image size in parentheses (for example, 36B (virtual 121MB)). |
| State | Current container state (for example, running or exited). |
| Image | Docker image name and registry path used by this container. |
| Tag | The image tag (for example, 0.10.4-qa). |
| Container Status | How long the container has been in its current state, and its health (for example, Up 49 minutes (healthy)). |
Container states
| State | Meaning |
|---|---|
running |
Container is actively executing. |
exited |
Container has stopped. |
Partition status section
Disk space utilization for every mount point on the ARP host.
| Column | Description |
|---|---|
| Mount Point | Filesystem mount path (for example, /, /boot, /var, or /home). |
| Available Storage | Free space available at this mount point. |
| Size | Total size of this filesystem. |
| Used | Space currently used on this filesystem. |
Storage values are expressed in human-readable units: bytes, MiB, or GiB.
Notable mount points
| Mount point | Purpose |
|---|---|
/ |
Root filesystem. OS and installed software. |
/boot |
Boot partition with kernel and initrd. |
/home |
User home directories. |
/kvm/<name> |
Storage for a KVM virtual machine (for example, /kvm/ubuntu). |
/mnt/gold-images |
Base image storage for VMs. |
/var/lib/docker |
Docker image and container storage layers. |
/var/log |
Log files. High usage here may indicate a runaway log condition. |
KVM status section
Status of KVM virtual machines running on the ARP host.
| Column | Description |
|---|---|
| Name | VM name (for example, mg). |
| Status | Current VM state: running, stopped, or paused. |
What to look for
- Memory Capacity close to 100% — the host is under memory pressure, which may cause container or VM instability.
- Physical interfaces down — a physical interface (
eno*) that should be connected showsdown. This may indicate a network connectivity issue. - Containers in
exitedstate — a container that should be running has stopped. Check the exit code and tag status string. /var/logpartition high usage — log rotation may not be functioning. If/var/logfills, the host cannot write new logs./kvm/<name>partition high usage — a virtual machine's disk is running out of space.- KVM VM not running — a virtual machine (for example,
mg) shows a status other thanrunning.
