Monitoring System Properties

The system properties include everything from the name and IP address of the device to the resource usage on the Routing Engine.

To view these system properties, select Monitor>Dashboard (SRX-series devices) or Monitor>System (J-series devices) in the J-Web interface.

Note: The J-Web GUI interface framework used on the SRX-series devices is based on panes. Each pane acts a separate frame that can be viewed, dragged, minimized, maximized, or hidden. The J-Web user interface has eight panes such as System identification, Resource utilization, Security resources, System alarms, File usage, Login sessions, Chassis status, and Storage usage.

Only the first three panes are displayed by default. To view the other system properties, click the Preferences icon at top right corner of the page. You can also set the refresh time interval for automatically updating the data on the system properties.

Alternatively, you can view system properties by entering the following show commands in the CLI configuration editor:

show system uptime
show system users
show system storage
show system processes

Table 89 through Table 94 summarize key output fields in the system properties displays.

Top 5 CPU-Consuming Processes
Process ID	Process identifier.	This is the PID field in the show system processes command output.
Process Owner	Name of the process owner.
Process Name	Command that is currently running.	Individual processes on the device are listed here. Because each process within JUNOS operates in a protected memory environment, you can diagnose whether a particular process is consuming an abnormal amount of resources. If a software process is using too much CPU or memory, you can restart the process by entering the restart command from the CLI.
CPU Usage	Percentage of the CPU that is being used by the process.	Note: On SRX series services gateway, the CPU and memory utilizations are done by monitoring the FPC card within the SPU units.
Show complete process information	—	Select to display the software processes running on the device. See Table 94.
Memory	Percentage of the installed RAM being used by all processes.
Process ID	Process identifier.	This is the PID field in the show system processes command output.
Process Owner	Name of the process owner.
Process Name	Command that is currently running.	Individual processes on the device are listed here. Because each process within JUNOS operates in a protected memory environment, you can diagnose whether a particular process is consuming an abnormal amount of resources. If a software process is using too much CPU or memory, you can restart the process by entering the restart command from the CLI.
Memory Usage	Percentage of the installed RAM that is being used by the process.
Show complete process information	—	Select to display the software processes running on the device. See Table 94.

Chassis Status	Status of the device chassis: OK (green)—Normal operation Failure (red)—Failed
Chassis Component Temperature
Name	Chassis component. For J-series devices, the chassis components are the Routing Engine and the fans.
Gauge Status	Status of the temperature gauge on the specified hardware comzponent.
Temperature	Temperature of the air flowing past the hardware component.
Chassis Fan Status
Name	Chassis component. For J-series devices, the chassis components are the Routing Engine, the Physical Interface Module (PIM) slot number (identified in the display as an FPC), and the PIM number (identified in the display as a PIC).	On J-series devices, an FPC and a PIM are the same physical unit. The PIM number is always 0.
Status	Status of the fans that are regulated by JUNOS software with enhanced services: OK Testing (when the device is powered on) Failed Absent
Fan Speed	Speed of the fans: normal or high speed.	Speed is adjusted automatically according to the current temperature.
Chassis Power Supplies
Name	Chassis component. For J-series devices, the chassis components are the Routing Engine, the Physical Interface Module (PIM) slot number (identified in the display as an FPC), and the PIM number (identified in the display as a PIC).	On J-series devices, an FPC and a PIM are the same physical unit. The PIM number is always 0.
