Name

Name of running station.

Host

IP address of host platform.

Model

Model of host platform type, such as “NMP6,” “JVLN,” or “Workstation.” See Models of platforms for further details.

Host ID

NiagaraAX host identifier, a string unique to this one machine.

Niagara Version

Version and build number of the NiagaraAX distribution running in the host platform.

Java VM Name

Java virtual machine used, e.g. either “Java HotSpot(TM) Client VM” or “J9” (QNX-based hosts) or “Java HotSpot(TM) Client VM” for Windows-based hosts.

Java VM Vendor

Vendor for Java VM, e.g. “Sun Microsystems Inc.” (Java HotSpot) or “IBM Corporation” (J9).

Java VM Version

Version of Java VM, e.g. “1.5.0_34-b26” (Java Hotspot) or “2.3” (J9)

OS Name

Operating System name, such as “QNX” or “Windows XP.”

OS Arch.

Machine architecture for OS, such as “ppc” (QNX-based hosts) or “x86” (Windows-based hosts)

OS Version

Operating System version, such as “6.4.1” (QNX) or “5.1” (Windows XP)

Platform Daemon Port

Port number on which the platform daemon that started the station is listening for its platform server (3011, or another port number). This can prove useful in case you changed the platform port (see Change HTTP Port), but then forgot what the new port is.

Platform Daemon SSL Port

Port number on which the platform daemon is listening for its platform SSL server (5011, or another port number, providing that platform SSL enabled). If platform SSL is disabled, it reads “Unknown”. This can prove useful in case you changed the platform SSL port (see Change SSL Settings), but then forgot what the new port is.

In the container plugin, most of the remaining entries are configuration parameters. However a few status values are also mixed in, and are described below.

Number of CPUs

Number of CPUs used in the host platform (typically 1).

Current CPU Usage

Percentage of CPU utilization in the last second.

Overall CPU Usage

Percentage of CPU utilization since the last reboot.

Filesystem

File storage statistics for the host, including total file space, available (free) space, and file block size (minimum size for even the smallest file). For a QNX-based JACE host, it may look similar to:

         Total       Free       Block
Size     Files  Max
Files
  /ffs0 126,976 KB  77,160
KB    2,048 bytes    732        4096
 /aram0  31,488 KB  29,832 KB    1,024
bytes     28        4096

The “Files” and “Max Files” values require the JACE to be running AX-3.6 or later.

Physical RAM

Current total and free RAM statistics for the host. For a QNX-based JACE, it may look similar to:

  Total       Free
  262,144 KB  70,160 KB

Serial Number

(Appears only if QNX-based JACE running AX-3.6 or later). The controller’s unique serial number.

Hardware Revision

(Appears only if QNX-based JACE running AX-3.6 or later). Hardware revision of the controller.

Hardware Jumper Preset

(Appears only if QNX-based JACE) Either true or false—indicates whether or not the mode jumper is installed for “serial shell mode” access. Read at boot time only. See “About JACE serial shell mode” in the JACE NiagaraAX Install & Startup Guide.

EWF Overlays

(Appears only if a CompactFlash-based JACE-NXT or JACE-NXS host) Status of the Enhanced Write Filter overlays which protect the CompactFlash card from excessive writes. Two overlays are listed, one for OS, and one for History. The current State can either be “Enabled,” “Disabled,” or “Unknown.” The state should always say “Enabled” for both overlays under normal operation. The Command should normally be “Commit.” Other possible values are “noCmd” and “CommitAndDisable.” Ram Usage is the amount of RAM used by the overlay, and should “cap out” at some maximum number during normal operation. The history overlay theoretical maximum is about 5% larger than the size of the History partition, about 85MB.
