MONITOR A SINGLE PROCESS

A single process can be monitored to check the CPU, EVENT FLAGS, I/O, PAGE FAULTS and QUOTA. After every interval period the actual values will be displayed. The default interval period is 3 seconds.

The selection of processes is based on the Process ID and the Process Name. Processes on another node in an OpenVMS Cluster can also be selected.

The display always contains a header with the Process ID, the Process Name, the Node Name (node where VIP runs and the node where the selected process runs, if this is a different node), a graduation and in some cases the Current Time and a Peak Value.

MONITOR PROCESS CPU

With MONITOR PROCESS CPU the CPU usage of a process will be monitored and displayed. After every interval period the Current Time and the CPU usage (in % and in a histogram) are displayed in a new line, so that a historical overview of the CPU usage arises.

The graduation has a default range of 100%, but can be increased when the node where the selected process runs has more than one processor.

MONITOR PROCESS EVENTFLAG

With MONITOR PROCESS EVENTFLAG the event flags of a process will be monitored and displayed. At least three 32-bit patterns will be displayed (cluster 0 = event flag 0 to 31, cluster 1 = event flag 32 to 63 and the event flag wait mask). Additional patterns of two common event flag clusters (cluster 2 en 3) can be displayed also.

When an event flag is set (0 -> 1) it can be displayed in reverse video during one interval period (for one specified cluster or for all clusters). It also rings a bell at the terminal.

MONITOR PROCESS I/O

With MONITOR PROCESS I/O the I/O rate of a process will be monitored and displayed. After every interval period the Current Time and the I/O rate (in figures and in a histogram) are displayed in a new line, so that a historical overview of the I/O rate arises.

The graduation has a default range of 100 I/O per second, but can be set to any value.

The direct en buffered I/O rate can be displayed as separate values or as added values (default).

MONITOR PROCESS PAGE FAULTS

With MONITOR PROCESS PAGE FAULTS the page fault rate of a process will be monitored and displayed. After every interval period the Current Time and the page fault rate (in figures and in a histogram) are displayed in a new line, so that a historical overview of the page fault rate arises.

The graduation has a default range of 2500 page faults per second, but can be set to any value.

MONITOR PROCESS QUOTA

With MONITOR PROCESS QUOTA the used or remaining process quota will be monitored and displayed. The displayed values are the AST Queue Limit, Buffered I/O Count Limit, Buffered I/O Byte Limit, CPU Time Limit, Direct I/O Count Limit, Lock Queue Limit, Open File Limit, Paging File Limit, Subprocess Creation Limit and Timer Queue Limit. After every interval period the actual values are displayed with every quota in a separate line. Each line contains the quota name, the used or remaining value of the quota (in figures, percentage and in a histogram) and the initital quota value.

When one of the above quota names is selected, a historical overview of that quota value arises.
