Status values in a station’s PlatformServicesContainer include the following:
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.
