MONITOR PROCESSES

The MONITOR PROCESSES command initiates monitoring of the PROCESSES class, which displays information about all processes in the system.
In a multifile summary request, the classes CLUSTER and PROCESSES are ignored. If these classes are the only classes specified on the command line, MONITOR does not recognize them and displays a "no classes specified" error message.

MONITOR PROCESSES

Command Qualifiers

/qualifier[,...]
One or more qualifiers as described in the Command Qualifier Descriptions section.

Classname Qualifiers

/TOPBIO
Specifies that a bar graph listing the top buffered I/O users be produced instead of the standard display and summary output. Values are expressed in units of buffered I/Os per second.
/TOPCPU
Specifies that a bar graph listing the top CPU time users be produced instead of the standard display and summary output. Values are expressed in units of clock ticks (10 milliseconds) per second.
/TOPDIO
Specifies that a bar graph listing the top direct I/O users be produced instead of the standard display and summary output. Values are expressed in units of direct I/Os per second.
/TOPFAULT
Specifies that a bar graph listing the top page faulting processes be produced instead of the standard display and summary output. Values are expressed in units of page faults per second.
/TOPRBS (VAX Only)
On OpenVMS VAX systems, specifies that a bar graph listing the top balance slot faulting processes be produced instead of the standard display and summary output. Values are expressed in units of balance slot faults per second.

Description

As illustrated in the examples, the PROCESSES display (and summary) formats are different from those of all other classes. The PROCESSES display provides the following information:

PID Process identifier as assigned by the system, in hexadecimal

STATE Process's scheduler state (see the description of the MONITOR STATES command for an explanation and a tabular summary of the STATES codes)

PRI Current (as opposed to base) priority of the process

NAME Process name

PAGES Number of shareable pages and total number of pages currently in use by the process

DIOCNT Cumulative direct I/O operations performed by the process since its creation; not displayed if the process is swapped out

FAULTS Cumulative page faults since the process was created; not displayed if the process is swapped out

CPU TIME Cumulative CPU time used by the process since its creation, in the format hours:minutes:seconds; not displayed if the process is swapped out

The top corners of the display contain the number of processes in the system and the time in days, hours, minutes, and seconds since the system was last booted. Processes that are swapped out are so noted.
If more processes are in the system than can be displayed on the terminal screen at once, the display consists of multiple screens. Screens are presented one at a time at intervals specified with the /VIEWING_TIME qualifier. The five /TOP bar graph displays provide the PID and process name of each of the top eight users.
As with the other bar graph displays, examples in the displays of top users are rounded to the nearest whole number. Up to eight processes with nonzero values are displayed. To be eligible for inclusion in the list of top users, a process must be present and swapped in at the beginning and end of the display interval. This eligibility requirement also applies to the beginning and ending of the entire period covered by a summary.
Note that only one of the displays of top users or the regular PROCESSES display can be selected in a single MONITOR request.

This example illustrates a PROCESSES display generated from the input file PROCS.DAT. One line is displayed for each process in the system. This display shows current values only---average, minimum, and maximum statistics are not available. Also for swapped-out processes, the words SWAPPED OUT replace the three rightmost items, because those items are not available for swapped-out processes. Because this example is a playback request, the system uptime displayed is that of the system at the time the MONITOR data was recorded.
Nondisplayable characters in process names are represented by periods.

MONITOR RMS

Command Qualifiers

/qualifier[,...]
One or more qualifiers as described in the Command Qualifier Descriptions section.

Classname Qualifiers

/ALL
Specifies that a table of all available statistics (current, average, minimum, and maximum) is to be included in the display and summary output. For summary output, this qualifier is the default for all classes; otherwise, it is the default for all classes except CLUSTER, MODES, PROCESSES, STATES, SYSTEM, and VECTOR.
/AVERAGE
Selects average statistics to be displayed in a bar graph for display and summary output.
/CURRENT
Selects current statistics to be displayed in a bar graph for display and summary output. The /CURRENT qualifier is the default for the CLUSTER, MODES, STATES, SYSTEM, and VECTOR classes.
/FILE=(file-name[,...])
Specifies a list of one or more files to which the MONITOR RMS command applies. If you include a node name as part of the file specification, MONITOR ignores the node name. Use the /NODE command qualifier to select specific nodes for MONITOR RMS requests. If you use the /NODE command qualifier to specify multiple nodes, the file must exist on all specified nodes. You can list up to 5,000 files. Do not specify wildcard characters.
/ITEM=(keyword[,...])
Selects one or more data items for inclusion in display and summary output. If you specify two or more keywords, enclose them in parentheses, and separate them with commas. When the /ITEM qualifier is omitted, the default is /ITEM=OPERATIONS.
The following table describes /ITEM qualifier keywords:

Keyword Description

Description

The SCS class is a component class. Data items for this class are collected for each node in the cluster. The SCS class consists of the following data items:

Data Item Description

Datagram Send Rate Rate at which datagrams are sent to another node.

Datagram Receive Rate Rate at which datagrams are received from another node.

Datagram Discard Rate Rate at which datagrams are discarded.

Message Send Rate Rate at which sequenced messages are sent to another node. Sequenced messages are exchanged between nodes to communicate with mass storage control protocol (MSCP) disks and the lock manager.

Message Receive Rate Rate at which sequenced messages are received from another node. Sequenced messages are exchanged between nodes to communicate with MSCP disks and the lock manager.

Send Data Rate Rate at which block send datas are initiated on the local node.

Kbytes Send Rate Rate at which kilobytes are sent, as a result of send datas initiated on the local node.

Request Data Rate Rate at which request datas are initiated on the local node.

Kbytes Request Rate Rate at which kilobytes are received, as a result of request datas initiated on the local node.

Kbytes Map Rate Rate at which kilobytes are mapped for block transfers. This is a rough measure of the data transfer rate between the local node and a remote node. Before any transfer can take place, a buffer must be mapped. The size of the accumulated buffers that were mapped is displayed by the Kbytes Map Rate. If request datas or send datas are initiated on the local or a remote node, then the Kbytes Map Rate reflects the number of kilobytes actually transferred between the two nodes.

Send Credit Queued Rate Rate at which connections are queued for a send credit. A connection is queued for a send credit whenever all of the buffers that were allocated by the remote node have been used.

Buffer Descriptor Queued Rate Rate at which connections are queued for a buffer descriptor. A connection is queued for a buffer descriptor whenever all of the buffer descriptors have been allocated by the local node. You can increase the number of buffer descriptors allocated on the local system by adjusting the system parameter SCSBUFFCNT.

Data Item	Description
Datagram Send Rate	Rate at which datagrams are sent to another node.
Datagram Receive Rate	Rate at which datagrams are received from another node.
Datagram Discard Rate	Rate at which datagrams are discarded.

Buffer Descriptor Queued Rate	Rate at which connections are queued for a buffer descriptor. A connection is queued for a buffer descriptor whenever all of the buffer descriptors have been allocated by the local node. You can increase the number of buffer descriptors allocated on the local system by adjusting the system parameter SCSBUFFCNT.

Example

MONITOR> MONITOR SCS

OpenVMS Monitor Utility SCS STATISTICS on node CURLEY 29-APR-1998 10:21:46 Kbytes Map Rate CUR AVE MIN MAX CURLEY 0.00 0.00 0.00 0.00 MOE 0.00 0.00 0.00 0.00 LARRY 0.00 0.00 0.00 0.00 SHEMP 5.64 3.81 1.98 5.64
