Process Zoom on a Graph
If you zoom-by-process on a graph, individual process data is listed as
shown in the following table.
If the graph shows a ranked summary (graph 1 for each set of
measurements), processes in all applications are represented in the
table. If the application graph shows an individual application (graph 2
for each set of measurements), only processes in the selected application
are listed.
Not all data can be displayed at once in the tabular window. Use the
vertical and horizontal scroll bars to see additional rows and columns.
Each table column lists a separate data element. Each row represents a
process that was logged because it was "interesting." A process becomes
interesting when it exceeds certain user-defined thresholds. For
information on defining thresholds, see the HP LaserRX/MPE User's Manual:
Collection Software.
Process Data Interest Reason Colors
HP LaserRX/MPE highlights process data with color to facilitate
perception of the interest reason. Interest reasons and associated
colors are listed in the following table.

in the table is used.
Process Data
The data elements in Table A-39 are presented when you
zoom-by-process on a graph. Column headings are listed in the order that
they appear (left to right) in the tabular window.
Table A-39. Zoom Process Data
---------------------------------------------------------------------------------------------
| | |
| Column Heading | Description |
| | |
---------------------------------------------------------------------------------------------
| | |
| Program Name | Program name of an active process or the MPE command that was last |
| | executed. |
| | |
| | When the Command Interpreter becomes an interesting process, CI is |
| | listed as the program name. The last command handled by the command |
| | interpreter after it becomes interesting is listed instead of CI if |
| | the data is available. The interesting process, however, is the |
| | Command Interpreter, not a process listed in the command. The first |
| | character of a command line is always a colon. |
| | |
---------------------------------------------------------------------------------------------
| | |
| Date | This is the date the observation was recorded on the host. |
| | |
---------------------------------------------------------------------------------------------
| | |
| Time | This is the time the observation was recorded on the host. |
| | |
---------------------------------------------------------------------------------------------
| | |
| % CPU Util | CPU Utilization as a percentage of total CPU available for this time |
| | interval.1 For multiprocessor systems, this is the total CPU |
| | available for a single processor. On a two-processor system, it is |
| | possible for each of two processes to show 100 percent CPU |
| | utilization during the same interval. Note that global and |
| | application CPU utilization of 100 percent means 100 percent of all |
| | processors. On MPE V systems, this value does not include any memory |
| | management CPU, but does include some of the time spent on disc |
| | caching while executing this process. On MPE XL systems, this value |
| | includes any memory management CPU consumed on behalf of this |
| | process. |
| | |
---------------------------------------------------------------------------------------------
| | |
| Phys Disc | Average number of physical disc I/Os per second for this time |
| | interval.1 For MPE V systems, this does not include memory manager |
| | transfers. For MPE XL systems, this value includes any memory |
| | management I/Os for the process. |
| | |
---------------------------------------------------------------------------------------------
| | |
| Sec/Intrvl | The number of seconds that the process was alive during the interval. |
| | |
---------------------------------------------------------------------------------------------
| |
| 1If a process was alive for less than 60 seconds during the sample interval, then the |
| % CPU Util and the disc I/O rate will be reported based on 60 seconds, not on the |
| Sec/Intrvl time. |

---------------------------------------------------------------------------------------------
| | |
| Proc Pri | Priority of the process. 1 (highest) to 255 (lowest). |
| | |
---------------------------------------------------------------------------------------------
| | |
| Interest Reason | The coded reason a process is interesting. A process becomes |
| | interesting when it is first created, when it terminates, and when it |
| | exceeds certain user-defined thresholds. Thresholds are set using |
| | the THRESHOLD and WAIT THRESHOLD directives in the PARM file. The |
| | PARM file is used by SCOPE(XL), the HP LaserRX/MPE collection |
| | program. Codes, interest reasons, and the color highlight assigned |
| | for each reason are as follows: |
| | |
| | C CPU Percent exceeded (Red) |
| | D Disc I/Os exceeded (Dark Blue) |
| | P To Prompt exceeded (Green) |
| | F First Response exceeded (Violet) |
| | T Transaction Rate exceeded (Light Blue) |
| | N Process creation (Black) |

| | c Wait on CPU percent exceeded (Black) |
| | d Wait on disc percent exceeded (Black) |
| | m Wait on memory percent exceeded (Black) |
| | i Wait on impede percent exceeded (Black) |

| | first (above) is used to display the process entry. |

| | |
| CM % | Percent of CPU used during the interval that was in compatibility |
| | mode (0-100). This is the percentage of the CPU that was used during |
| | the interval, not the percentage of the interval. For example, if a |
| | process shows 80 percent in CM, then 20 percent of its CPU used was |
| | native mode. This number is independent of the CPU Util % metric. |
| | (MPE XL only.) |
| | |
| Switch to NM | The rate of switches from compatibility mode to native mode during |
| | the interval in switches per second.1 (MPE XL only.) |
| | |
---------------------------------------------------------------------------------------------

| Switch to CM | The rate of switches from native mode to compatibility mode during |

---------------------------------------------------------------------------------------------
NOTE On MPE XL systems there is a relatively high ratio of logical disc
I/O to physical disc I/O. In part this is due to MPE XL caching of
disc writes as well as reads. To a larger degree, it is due to a
definition of a logical I/O that is different than the one used on
MPE V systems.
Under MPE V, a logical I/O occurs when the file system makes a
request to the I/O system to transfer a block of data to or from a
disc file. Under MPE XL, a read attempt or write attempt occurs
whenever a program makes a request of the file system to transfer
data.
These transfers may occur at each record, at each block (if
multi-record I/O is done), or not at all (if mapped files are
used). MPE XL read/write attempts are the closest metric to the
MPE V logical I/Os, but they are not equivalent.
