All monitored linux images
The SYLOVRZR view can be accessed directly by entering the view name on the COMMAND line or from an easy menu option under Utilities and Linux Image Status. This view provides the following information for each Linux system that is being monitored by the active PAS:
- host name of each Linux system image
- status (inactive, running, or idle)
- CPU usage (percentage)
- memory usage (percentage)
- swap space usage (percentage)

From the SYLOVRZR view, you can perform the following actions for a managed Linux system. These actions are described in below content.
SYLOVRZR actions
Action | Description |
|---|---|
CNS | cancel a previous shutdown request (shutdown -c) |
DEL | delete an inactive image This action removes the inactive image from image file so it will not be displayed on the SYLOVRZR view. |
HLT | halt a Linux system (shutdown -h now) |
RBT | reboot a Linux system (shutdown -r) |
STA | start a Linux system |
WRN | send a warning message to all processes (shutdown -k |
UPD | update the Linux data server and bgscollect programs by pulling down the latest RPMS files from your MVS host after a PTF has been applied |
Heartbeat data
Data for the SYLOVRZR view comes from heartbeat data that is sent every heartbeat interval from each Linux system to the PAS. For more information about heartbeat data, see Heartbeat data.
You can use the SYLOVRZR view to obtain status information quickly about all the monitored Linux system images being monitored that are connected to the PAS owning the current context.
System resource information
The System Resource Usage (SYLUSER) view, displays system resource information. This view can be accessed directly by view name or from the Activity > Resource Usage option on the EZLSYSR Easy Menu. The SYLUSER view includes the following information:
- monitored Linux image name
- CPU usage (percentage)
- average number of processes that are waiting for CPU service (per second)
- average number of times that the run queue is updated during the measurement interval (per second)
- average number of processes that are ready to run (for 1-, 5-, and 15-minute intervals)
- number of processes running during the measurement interval
- total amount of physical memory that is in use during the measurement interval
