Process Manager displays and provides access to processes that are running on your workstation.
Each process entry in the list gives you useful information, as explained in the following table:
Column Heading | Meaning |
---|---|
ID | Process ID |
Name | Process Name |
Owner | Name of Owner |
CPU% | Ratio of CPU time used recently to time available in the same period, expressed as a percentage |
RAM | Amount of RAM currently occupied by this process |
Swap | Total size in virtual memory |
Started | Actual start time (or date if other than current) |
Parent | Process ID of parent process, or PPID |
Command | Actual UNIX command (truncated) being executed |
You can perform the following actions without affecting any processes on the selected workstation:
Display all processes, or only those containing a specified character string
Find processes containing a specified character string
Display processes sorted by any of the columns in the scrolling pane
Change the sampling interval, and copy and save the sample information
Click the Find Process control on the Tools subpanel of the Front Panel.
The Process Manager main window is displayed. It immediately samples the workstation and displays a sample of all current processes.
Type your filter text into the Filter field of the Process Manager window.
You filter text should be a string of characters that is common to the process entries of the subset or group of processes you want to display. For example, in Figure 19–1 the user is displaying all processes relating to Audio Tool.
Press Return.
Process Manager updates the processes in the scrolling pane to include only those process entries that contain an exact match of the filter text.
To revert to displaying all processes, clear the Filter field and press Return.
Type your search text into the Find drop-down box, or select a previously used search text from the Find drop-down list.
Your search text should be a string of characters that is common to the process entries of all of the processes you want to display.
Press Return to highlight the first occurrence of the search text below the current cursor position.
The text can be in any of the fields in the process entry.
Press Return to highlight the next occurrence, and so on.
When you have found the required process entry, clear the Find field.
When you reach the end of the scrolling pane, search does not revert to the top of the list. Therefore, to ensure you search all processes, select the first process entry in the list before typing your search text in the Find box.
By default, Process Manager lists the process entries in order of decreasing CPU usage. You can tell this because the column heading over the CPU usage column (CPU%) is depressed, while the other column headings are not.
To select the column on which the list of process entries is to be sorted, click the relevant column heading or choose the column name from the View menu.
Process Manager sorts the list of process entries and displays them in the new order. The default ordering for each column is indicated in the following table.
Table 19–1 Default Display Order for Process EntriesSelected Column Heading | Method |
---|---|
ID | Sorts numerically by process ID in increasing order |
Name | Sorts alphabetically by process name |
Owner | Sorts alphabetically by owner name |
CPU% | Sorts numerically by CPU usage in decreasing order |
RAM | Sorts numerically by RAM usage in decreasing order |
Swap | Sorts numerically by swap space usage in decreasing order |
Started | Sorts chronologically by actual start time in decreasing order |
Parent | Sorts numerically by process ID number of parent process in decreasing order |
Command | Sorts alphanumerically by full path name in decreasing order ( characters such as / have a lower sort value than letters) |
(Optional) To reverse the sort order for any one of these columns (for example, to sort by RAM usage in increasing order), click the depressed column heading button.
The column heading area will turn black and sort the display in the reverse order.
By default, Process Manager samples the workstation and updates the display every 30 seconds.
To disable/enable the continuous sampling mode, choose Stop/Start from the Sample menu.
If continuous sampling is on, you will see a Stop menu item on the Sample menu; otherwise the menu item will read Start.
To change the interval between samples, type a number of seconds (up to 604800, that is, 14 days) in the Sample Every box.
Press Return to make the new sampling frequency come into effect.
To sample immediately, choose Now from the Sample menu.
Process Manager samples and then updates the display.
You can select and copy one or more of the process entries in the display, and paste the text into other applications.
You also have the following options for saving the sample data to files:
Creating a new file containing only the current sample
Setting up a log file to which each new sample is appended
Choose Save As from the Sample Menu.
Process Manager displays the Save As dialog box.
Specify the name and location of a new file and click OK.
Process Manager creates the text file containing the process entries from the current display.
Choose Log File from the Sample menu.
Process Manager displays the Log File dialog box.
Specify the name and location of a new file and click OK.
Process Manager creates the text file and appends each new sample (with header information) to the file.
Process Manager will continue to append to this file until you terminate the Process Manager application, or until you choose Stop Logging from the Sample menu.
