Information is displayed about Batch, Network and Interactive processes, Batch queues, Print queues, Peripheral devices, and System statistics. .br .in 0 2 Internal_Commands .in 2 .br While SYMON is running, the user can enter commands which modify the way SYMON operates. Typing the H key will provide help on SYMON. Typing Control-W will redraw SYMON's screen. Typing Control-Z will exit from SYMON. Typing the B key will release the current broadcast message if the HOLDBROADCAST qualifier is in effect. .br .in 0 2 Command_Qualifiers .br /INTERVAL=n .in 2 This qualifier controls the time interval between updates of the screen. For example: $ SYMON/INTERVAL=5 would update the screen every 5 seconds. The default is to update the screen every 10 seconds. .in 0 /NOLOOP .in 2 This qualifier specifies that only one screen should be output. This qualifier is useful when sending output to a file. For example: $ DEFINE/USER SYS$OUTPUT SYMON.OUT $ SYMON/NOLOOP would send one screen full of information to the file SYMON.OUT. .br .in 0 /HOLDBROADCAST .IN 2 This qualifier specifies that broadcast messages should be held until the "B" key is pressed at the keyboard. Normally, broadcast messages are displayed for only one update pass, and then erased. This qualifier causes the messages to be held until the user types the "B" key to go to either the next broadcast message or to the status display on the next update. .in 0 2 Process_Display .in 2 .br The Process display shows information on processes executing in the system. The heading for the Process display shows the number of interactive, batch, and network users. Each line of the display shows information about a process. The username, the base priority, the type of process (interactive (I), interactive subprocess (S), batch (B), batch subprocess (b), network (N), or network subprocess (n)), whether the process is disconnected, the current state of the process (see status_codes below) and the percent of total system processor time the process has used since the last Process display update is shown. For example: MYPROCESS (04)I*LEF 5% would show that the user MYPROCESS was an interactive process with a priority of 4, in wait local event flag state, and used 5% of the total system processor time since the last screen update. The asterisk indicates that the process is disconnected. .br .in 0 3 Status_codes .in 2 .br The status of processes listed in the Process display are presented in the following table: .sp Code State Name Description .sp COM/CMO Computable Waiting for the processor. CEF Common Event Flag Waiting for something to happen in the image. CPG Collided Page Waiting for the system. CUR Current Executing on the processor. FPG Free Page Wait Waiting for physical memory. LEF/LFO Local Event Flag Waiting for something to happen in the image. HIB/HBO Hibernating Intentionally doing no work. MWT Mutex/Miscell. Waiting for a resource. SUS/SPO Suspended Intentionally doing no work. PFW Page Fault Wait Waiting for the system. .sp Codes ending with the letter O indicate that the associated process is outswapped; it has been temporarily removed to disk to free memory. Both HIB and SUS indicate inactive processes. Suspended processes have been suspended by another process and must wait to be activated. Hibernating processes, however, can reactivate themselves. .br .in 0 2 Batch_Queue_Display .in 2 .br The Batch Queue display shows information on the batch queues known to the system. The heading for the Batch Queue display shows the total number of jobs in all queues and the number of jobs currently executing. Each line of the display show the first 12 characters of the queue name, the current status of the queue (see status_codes below), the number of jobs in the queue and the number of jobs currently executing from the queue. For example, SYS$BATCH ACT 6/2 indicates that the queue SYS$BATCH is currently active, that there are 6 jobs currently in the queue, 2 of which which are currently executing. .br .in 0 3 Status_codes .in 2 .br The status of queues listed in the queue displays are presented in the following table: ALN - queue is waiting for paper to be aligned IDL - queue contains no active jobs PSD - queue is paused PSG - queue is pausing REM - queue is assigned to a remote device RST - queue is resetting and stopping RES - queue is restarting after pausing SRV - queue processing is directed to a server STL - queue is stalled STR - queue is starting STP - queue is stopped STG - queue is stopping UNV - queue is unavailable .br .in 0 2 Print_Queue_Display .in 2 .br The Print Queue display shows information on the print queues known to the system. The heading line shows the total number of jobs in all the queues. Each line of the display shows the first 12 characters of the queue name, the current state of the queue, any forms that are in use or needed for the queue, and the number of jobs in the queue. For example: SYS$PRINT *IDL(015) 2 indicates that the queue SYS$PRINT is currently idle. The asterisk (*) indicates that there is at least one job in the queue that needs a special stock mounted. The number in parenthesis is the number of the form currently associated with the queue. The last number on the line indicates that there are 2 jobs currently in the queue. .br .in 0 2 Peripheral_Display .in 2 .br The Peripheral display shows the status of the disk and tape units connected to the system. The disk and tape units are displayed separately. Each line of the disk display shows the name of the drive, whether it is allocated, whether it is mounted, the number of errors on the device and the percent of space used on the device. For example: DUA1 M 0 65% full indicates that DUA1 is mounted, has had no errors and is 65% full. Each line of the tape display shows the name of the drive, whether it is allocated, whether it is mounted, the number of errors on the device and the volume name of the tape mounted on the device. For example: MUA0 AF 5 TAPEUSER indicates that MUA0 is allocated, mounted foreign, has had 5 errors since the last time the error counter was reset, and the drive is currently allocated to user TAPEUSER. .br .in 0 2 System_Statistics_Display .in 2 .br The System Statistics display shows various information about the system. It shows the current date and time, the date and time the system was last boot loaded, the system node name, the VMS release number, the percent of processor time the system was idle, and the number of pages in the free and modified page lists. In addition, the page fault rate, and the direct and buffered I/O rates are displayed. If you receive a Broadcast message while in SYMON, it will be displayed in the System Statistics display area for one update of the screen. Then the system statistics as described above will be displayed. .pl 0
