2011-04-14 02:38:14 +05:30
|
|
|
The \*(WE program provides a dynamic real-time view of a running system.
|
2011-03-31 16:45:12 +05:30
|
|
|
It can display\fB system\fR summary information as well as a list of
|
|
|
|
\*(TT currently being managed by the Linux kernel.
|
2002-07-25 03:55:34 +05:30
|
|
|
The types of system summary information shown and the types, order and
|
2011-03-31 16:45:12 +05:30
|
|
|
size of information displayed for processes are all user configurable
|
|
|
|
and that configuration can be made persistent across restarts.
|
2002-07-25 03:55:34 +05:30
|
|
|
|
2002-10-24 03:18:11 +05:30
|
|
|
The program provides a limited interactive interface for process
|
|
|
|
manipulation as well as a much more extensive interface for personal
|
2011-03-31 16:45:12 +05:30
|
|
|
configuration \*(Em encompassing every aspect of its operation.
|
2011-04-14 02:38:14 +05:30
|
|
|
And while \*(WE is referred to throughout this document, you are free
|
2002-07-25 03:55:34 +05:30
|
|
|
to name the program anything you wish.
|
2011-04-14 02:38:14 +05:30
|
|
|
That new name, possibly an alias, will then be reflected on \*(We's

When operating \*(We, the two most important keys are the help (h or ?)
|
2011-03-31 16:45:12 +05:30
|
|
|
key and quit ('q') key.
|
2014-04-23 10:30:02 +05:30
|
|
|
Alternatively, you could simply use the traditional interrupt key (^C)
|
2002-10-24 03:18:11 +05:30
|
|
|
when you're done.
|
|
|
|
|
2013-01-16 11:30:00 +05:30
|
|
|
When started for the first time, you'll be presented with these traditional
|
|
|
|
elements on the main \*(We screen: 1) Summary Area; 2) Fields/Columns Header;
|
|
|
|
3) Task Area.
|
|
|
|
Each of these will be explored in the sections that follow.
|
|
|
|
There is also an Input/Message line between the Summary Area and Columns
|
|
|
|
Header which needs no further explanation.
|
|
|
|
|
|
|
|
The main \*(We screen is \fIgenerally\fR quite adaptive to changes in
|
|
|
|
terminal dimensions under X-Windows.
|
|
|
|
Other \*(We screens may be less so, especially those with static text.
|
|
|
|
It ultimately depends, however, on your particular window manager and
|
|
|
|
terminal emulator.
|
|
|
|
There may be occasions when their view of terminal size and current contents
|
|
|
|
differs from \*(We's view, which is always based on operating system calls.
|
|
|
|
|
|
|
|
Following any re-size operation, if a \*(We screen is corrupted, appears
|
|
|
|
incomplete or disordered, simply typing something innocuous like a
|
|
|
|
punctuation character or cursor motion key will usually restore it.
|
|
|
|
In extreme cases, the following sequence almost certainly will:
|
2013-06-20 10:30:00 +05:30
|
|
|
.nf
|
2013-01-16 11:30:00 +05:30

|
|
|
.fi
|
2013-01-16 11:30:00 +05:30
|
|
|
|
|
|
|
But if the display is still corrupted, there is one more step you could try.
|
|
|
|
Insert this command after \*(We has been suspended but before resuming it.
|

|
|
|
\*(NT the width of \*(We's display will be limited to \*(WX positions.
|
|
|
|
Displaying all fields requires \*(WF characters.
|
|
|
|
Remaining screen width is usually allocated to any variable width columns
|
|
|
|
currently visible.
|
|
|
|
The variable width columns, such as COMMAND, are noted in topic
|
|
|
|
3a. DESCRIPTIONS of Fields.
|
|
|
|
Actual output width may also be influenced by the \-w switch, which is
|
|
|
|
discussed in topic 1. COMMAND\-LINE Options.
|
|
|
|
|
2013-01-16 11:30:00 +05:30
|
|
|
Lastly, some of \*(We's screens or functions require the use of cursor
|
|
|
|
motion keys like the standard \*(KAs plus the Home, End, PgUp and PgDn keys.
|
2011-03-31 16:45:12 +05:30
|
|
|
If your terminal or emulator does not provide those keys, the following
|
2013-01-16 11:30:00 +05:30
|
|
|
combinations are accepted as alternatives:

The \fBUp\fR and \fBDown\fR \*(KAs have special significance when prompted
|
|
|
|
for line input terminated with the <Enter> key.
|
|
|

Those keys, or their aliases, can be used to retrieve previous input lines

|
|

which can then be edited and re-input.

The fields related to \*(MP or \*(MV reference `(KiB)' which is the

top: provide the means to adjust scaled process memory
This commit is an unrequested outgrowth of the earlier
change dealing with summary area memory field scaling.
That user selectable scaling provision is now extended
to include 6 (at present) task oriented memory fields.
The new companion 'e' (lower case) interactive command
has been added and, like the 'E' command, it can cycle
each of the currently displayed memory columns between
KiB through TiB. There are, however, some differences.
Where '+' indicates summary area truncation at a given
radix, task memory fields are automatically scaled for
their column. Thus, not all rows use the same scaling.
And, while summary area field widths were not changed,
the task memory columns were widened in order to offer
more meaningful data when the radix was increased. The
precision is automatically increased in step with each
radix: MiB displays 2 decimal places, GiB 3 and TiB 4.
To compliment that additional precision, both the %CPU
and %MEM fields were widened by 1 column and now offer
precision up to 3 decimal places. But, unique to %CPU,
widening could already have occurred due to the number
of processors in some massively parallel boxes. At any
rate, total extra width for both memory and percentage
fields could amount to twenty (precious) columns more.
So for both the memory and % fields the original width
(along with loss of precision) can be restored via new
compiler conditionals which this commit also provides.
p.s. and it will be rcfile preserved for any restarts!
(now that we know a '.' + 2 spaces is squeezed to one)
(everything's perfectly justified, but it's just luck)

top: provide the means to adjust scaled process memory
This commit is an unrequested outgrowth of the earlier
change dealing with summary area memory field scaling.
That user selectable scaling provision is now extended
to include 6 (at present) task oriented memory fields.
The new companion 'e' (lower case) interactive command
has been added and, like the 'E' command, it can cycle
each of the currently displayed memory columns between
KiB through TiB. There are, however, some differences.
Where '+' indicates summary area truncation at a given
radix, task memory fields are automatically scaled for
their column. Thus, not all rows use the same scaling.
And, while summary area field widths were not changed,
the task memory columns were widened in order to offer
more meaningful data when the radix was increased. The
precision is automatically increased in step with each
radix: MiB displays 2 decimal places, GiB 3 and TiB 4.
To compliment that additional precision, both the %CPU
and %MEM fields were widened by 1 column and now offer
precision up to 3 decimal places. But, unique to %CPU,
widening could already have occurred due to the number
of processors in some massively parallel boxes. At any
rate, total extra width for both memory and percentage
fields could amount to twenty (precious) columns more.
So for both the memory and % fields the original width
(along with loss of precision) can be restored via new
compiler conditionals which this commit also provides.
p.s. and it will be rcfile preserved for any restarts!
(now that we know a '.' + 2 spaces is squeezed to one)
(everything's perfectly justified, but it's just luck)

While \*(We will try to honor the selected target range, additional

scaling might still be necessary in order to accommodate current values.

You can use this Other Filter feature to establish selection criteria which

2013-03-03 11:30:00 +05:30

2013-03-03 11:30:00 +05:30
|
|
|
3) a selection value, as a minimum.

When prompted for selection criteria, the data you provide must take one

There are 3 required pieces of information, with a 4th as optional.

Items #1, #3 and #4 should be self\-explanatory.
|
|
|
|
Item \fB#2\fR represents both a required \fIdelimiter\fR and the \fIoperator\fR
|
2014-05-07 10:30:00 +05:30
|
|
|
which must be one of either equality (`=') or relation (`<' or `>').

2013-03-05 11:30:00 +05:30
|
|
|
|
2014-04-23 10:30:03 +05:30
|
|
|
The `=' equality operator requires only a partial match and that
|
|
|
|
can reduce your `if\-value' input requirements.
|
|
|
|
The `>' or `<' relational operators always employ string comparisons,
|
2013-03-05 11:30:00 +05:30
|
|
|
even with numeric fields.
|
|
|
|
They are designed to work with a field's default \fIjustification\fR and
|
|
|
|
with homogeneous data.
|
|
|
|
When some field's numeric amounts have been subjected to \fIscaling\fR
|
|
|
|
while others have not, that data is no longer homogeneous.
|
|
|
|
|
2014-04-23 10:30:01 +05:30
|
|
|
If you establish a relational filter and you \fBhave\fR changed the
|
2014-04-23 10:30:02 +05:30
|
|
|
default Numeric or Character \fIjustification\fR, that filter is likely to fail.
|
2013-03-05 11:30:00 +05:30
|
|
|
When a relational filter is applied to a memory field and you \fBhave not\fR
|
|
|
|
changed the \fIscaling\fR, it may produce misleading results.
|
2014-04-23 10:30:03 +05:30
|
|
|
This happens, for example, because `100.0m' (MiB) would appear greater
|
|
|
|
than `1.000g' (GiB) when compared as strings.
|
2013-03-05 11:30:00 +05:30
|
|
|
|
|
|
|
If your filtered results appear suspect, simply altering justification or
|
|
|
|
scaling may yet achieve the desired objective.

To exploit the `Y' \*(CI, you must add entries at the\fB end\fR of the
|
2012-11-25 11:30:06 +05:30
|
|
|
\*(We personal \*(CF.
|
|
|
|
Such entries simply reflect a file to be read or command/pipeline to be
|
|
|
|
executed whose results will then be displayed in a separate scrollable,
|
|
|
|
searchable window.
|
|
|
|
|
2014-04-23 10:30:03 +05:30
|
|
|
If you don't know the location or name of your \*(We rcfile, use the `W'
|
2012-11-25 11:30:06 +05:30
|
|
|
\*(CI to rewrite it and note those details.
|
|
|
|
|
|
|
|
Inspect entries can be added with a redirected echo or by editing the \*(CF.
|
|
|
|
Redirecting an echo risks overwriting the rcfile should it replace (>)
|
|
|
|
rather than append (>>) to that file.
|
|
|
|
Conversely, when using an editor care must be taken not to corrupt existing
|
|
|
|
lines, some of which will contain unprintable data or unusual characters.
|
|
|
|
|
2014-04-23 10:30:03 +05:30
|
|
|
Those Inspect entries beginning with a `#' character are ignored, regardless
|
2012-11-25 11:30:06 +05:30
|
|
|
of content.
|
|
|
|
Otherwise they consist of the following 3 elements, each of which\fI must\fR
|
2014-04-23 10:30:03 +05:30
|
|
|
be separated by a tab character (thus 2 `\\t' total):
|
2012-11-25 11:30:06 +05:30

2013-06-20 10:30:00 +05:30

The two types of Inspect entries are\fI not\fR interchangeable.
|
2014-04-23 10:30:03 +05:30
|
|
|
Those designated `\fBfile\fR' will be accessed using fopen and
|
|
|
|
must reference a single file in the `.fmts' element.
|
|
|
|
Entries specifying `\fBpipe\fR' will employ popen, their `.fmts' element
|
2012-11-25 11:30:06 +05:30
|
|
|
could contain many pipelined commands and, none can be interactive.
|
|
|
|
|
2014-04-23 10:30:03 +05:30
|
|
|
If the file or pipeline represented in your `.fmts' deals with the specific PID
|
2013-05-13 10:30:00 +05:30
|
|
|
input or accepted when prompted, then the format string must also contain
|
2014-04-23 10:30:03 +05:30
|
|
|
the `\fB%d\fR' specifier, as these examples illustrate.
|
2012-11-25 11:30:06 +05:30

|
|
|
|
2014-04-23 10:30:03 +05:30
|
|
|
For `\fBpipe\fR' type entries only, you may also wish to redirect stderr to
|
2012-11-25 11:30:06 +05:30
|
|
|
stdout for a more comprehensive result.
|
|
|
|
Thus the format string becomes:

Here are examples of both types of Inspect entries as they might appear
|
|
|
|
in the rcfile.
|
2014-04-23 10:30:03 +05:30
|
|
|
The first entry will be ignored due to the initial `#' character.
|
2012-11-25 11:30:06 +05:30
|
|
|
For clarity, the pseudo tab depictions (^I) are surrounded by an
|
|
|
|
extra space but the actual tabs would not be.

|
2012-11-25 11:30:06 +05:30

as well.

Lastly, as the number of your Inspect entries grows over time, the `Options:'

2012-11-25 11:30:06 +05:30

|

That does not affect operation other than to make some selections invisible.

However, if some choices are lost to truncation but you want to see more options,

there is an easy solution hinted at below.

The entries in the \*(We rcfile would have a number for the `.name' element and
|
|
|
|
the `help' entry would identify a shell script you've written explaining what
|
2012-11-25 11:30:06 +05:30
|
|
|
those numbered selections actually mean.
|
|

In that way, many more choices can be made visible.

The user interface, through prompts and help, intentionally implies
|
|
|
|
that the delay interval is limited to tenths of a second.
|
|
|
|
However, you're free to set any desired delay.
|
|
|
|
If you want to see Linux at his scheduling best, try a delay of .09
|
|
|
|
seconds or less.
|
|
|
|
|
|
|
|
For this experiment, under x-windows open an xterm and maximize it.
|
|
|
|
Then do the following:
|
2013-06-20 10:30:00 +05:30
|
|
|
.nf
|
2002-10-02 05:40:30 +05:30
|
|
|
. provide a scheduling boost and tiny delay via:
|
2013-01-02 11:30:00 +05:30
|
|
|
nice -n -10 \*(We -d.09
|
2011-03-31 16:45:12 +05:30
|
|
|
. keep sorted column highlighting \*F so as to
|
|
|
|
minimize path length
|
2002-07-25 03:55:34 +05:30
|
|
|
. turn \*O reverse row highlighting for emphasis
|
|
|
|
. try various sort columns (TIME/MEM work well),
|
2002-10-02 05:40:30 +05:30
|
|
|
and normal or reverse sorts to bring the most
|

What you'll see is a very busy Linux doing what he's always done for you,

2011-03-31 16:45:12 +05:30

Then set the delay interval to around .3 seconds.

If necessary, use the `c' \*(CT to display command lines and ensure

2012-09-20 12:32:02 +05:30
