Subject description: (next to the date)
 

#===========================================
Some Background:
(a) I use a DELL 2001 desk-top computer, 1G RAM, 3G CPU speed,
and ALL Linux code is booted from and kept on Flash-Drives.
Hard Drives are removed.
This has provided excellent physical portability and physical security
for the entire time since I switched from M$XP systems.
(b) Installation is via copying required "frugal" files from the .ISO
onto the target USB flashdrive media ,
and modifying the Grub4Dos coded menu.lst to pick-up kernel and initrd.
This simple process has worked flawlessly for Puppy, Ubuntu, Knoppix,
etc. , so I have never had to use a supplied "installer" since the beginning.
(c) Automatic-System-Saves to User-Save-File is always disabled.
A System-Save icon is vividly posted on the screen.
Shut-Down AskToSave timeout is changed to 6 seconds.
This provides some security from internet/browser malware activity.
This provides some security from my own mucking/testing of BASH.


#===========================================
Statement of Question:

(a) Puppy derivatives always have a little resource indicator icon,
the "System-Bar-Graph" next to the date.
What is it monitoring?

(b) Puppy derivatives always have a little resource icon ,
the "Green-Cylinder" indicator, on the bottom of screen.
What is it monitoring?

(c) I am Running puppy-Widget with a "Widget-Ram-Bar" Indicator,
What is it monitoring?


#===========================================
Note:

These "RAM" indicators seldom, if ever, match during a work session.

For example,
When I run a commercial SPICE simulator via browser,
(1) then the Widget-Ram-Bar is mostly accurate.
(2) then the System-Bar-Graph is accurate.
(3) then the Green-Cylinder is not accurate.
(4) then I must monitor the CPU Usage Indicator to avoid a Lock-Up.

Sometimes, but not always,
the Green-Cylinder will go RED,
over-riding any other indicator,
and the system "must be rebooted to clear RAM" comes up in "red".

#=======================================
Hats-Off to the very talented Barry Kauler
for his very original Puppy Linux distro !

As for thr graph, that is called xload, about two or three posts above this one there is a sticky all about it
xload is NOT a CPU usage meter

The cylinder thing represents storage space available, in your case of your save file(or RAM). When it goes red your computer is getting
ready to melt down Shocked .

Actually, red means your storage space is almost full, which means your save file (or maybe RAM) is almost full. In puppy with a frugal
install that is the same as running out of disk space.

If doing disk intensive work in puppy, the save file (or RAM) can fill up quick if it is small (such as copying files to the puppy system)

With no automatic pupsave you are ~probably running out of RAM when locking up the system. The reason behind that would be that
whatever you are doing has to reside somewhere on the system. Puppy holds your changes in RAM until saved. Lots of file activity
such as copying big or a lot of files would equal lots of RAM getting used for stoage until it gets unloaded to the save file (or deleted).

You can resize (make bigger) the save file with the utility
Menu -->Utility -->Resize personal storage file
Some info about resizing save file from the puppy linux FAQ

As for the puppy widget ram bar, I don't have a clue. Someone else will though. Puppy-On!

Hello, glene77is.

You asked:

If you mean the ram-bar like the one in this picture:
http://www.murga-linux.com/puppy/viewtopic.php?p=249211&sort=lastpost#249211
(the picture is a bit down zigbert's post),

Very simply put, it is indicating your available RAM, on a bar, without any numbers
or percentages.

If it is close to the left, (in other words if you have lots of empty space in the bar)
your computer is not using much RAM. Conversely, if it is close to the right, (in other
words if you have a lot of white), your computer is using a lot of RAM.

IHTH. BFN.

This situation can often be avoided by having more "swap" space (not the same thing as savefile)

I use a fast 4GB or 8GB usb stick formatted by Gparted with one "Linux-Swap" partition and nothing else on it. Either boot the system with such a drive plugged in (puppy will automatically detect and use it) or else boot with the stick out (might be necessary depending on what your bios does when it sees a usb stick during boot) and after the system has booted use a terminal and enter the following command to get puppy to use the newly plugged in swap stick:

swapon /dev/sdc1

(or specifying whatever device name is actually your swap formatted usb stick)
