xfce4 panel plugin hardware-monitor

xfce4-hardware-monitor-plugin's Introduction

26.11.14: Now accepted/moved into XFCE4 panel-plugins! http://git.xfce.org/panel-plugins/xfce4-hardware-monitor-plugin/

Hardware Monitor
----------------

Hardware Monitor is a monitor plugin for the XFCE4 panel (originally
the GNOME panel). It supports a variety of monitoring capabilities
(CPU usage, network throughput etc.) and different kinds of viewers
(curves, bars, columns, text, flames).

It is licensed under the GNU GPL v3 or later.

Breaking changes
----------------

1.4.6 upgrade: See NEWS/Changelog.

Requirements
------------

You need a modern XFCE4 desktop (i.e. at least XFCE 4.4 I think) with
the related libraries and the C++ wrappers for GTK+ and the Gnome
canvas library - gtkmm, libglademm and libgnomecanvasmm.
These can be fetched from http://www.gtkmm.org, or are alternatively
probably available as packages from your distributor.

Also, to compile the program you need the development files for the
XFCE4 panel, the XFCE4 user interface library libgtop. The following
are the correct packages on Debian Testing as of 7.11.13:

libglademm-2.4-dev libgnomecanvasmm-2.6-dev libgtkmm-2.4-dev libgtop2-dev
libxfce4ui-1-dev xfce4-panel-dev

If you have libsensors from the lm-sensors package installed at
compile time, the configure script will detect it and add support for
monitoring temperatures and fan speeds (if the library is not found,
the relevant UI is hidden).

libgnomecanvas (which libgnomecanvasmm binds) has a stupid memory leak
in its paint routine, which I have reported:

My bug: OmegaPhil/hardware-monitor-applet#5
Debian bug: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=753621
GNOME bug: https://bugzilla.gnome.org/show_bug.cgi?id=729717

In both cases the bug has been ignored. Running the plugin for days will
gradually cause the RSS to increase without limit - for Debian users I
have produced fixed i386 and amd64 Debian archives -
https://github.com/OmegaPhil/libgnomecanvas/tree/pkg

Compiling from source
---------------------

Note that when you compile from source, the file
hardware-monitor.desktop must end up a place where the panel can find
it. Else you will not be able to find the plugin in the right-click
panel menu. This place is usually /usr/share/xfce4/panel/plugins/. If you
run configure with

./configure --prefix=/usr

and install the plugin, it will work.

To set up the build environment for the usual ./configure && make &&
make install, run the provided autogen.sh script first - autoconf, libtool
and intltool need to be installed for this script to work.

xfce4-hardware-monitor-plugin's Issues

disk statistics not working - regex match failure

i want to monitor disk usage, similar to sudo iotop

config for xfce4-hardware-monitor-plugin:
device > storage > disk statistics
disk: sda
stat: number of bytes read per duration

problems:
in the config-dropdown 'disk' no disks are suggested
values are always zero, mouse-hover says: -nan B/s

console output:

Unable to parse device stats line from '/proc/diskstats' - regex match failure:

   8       0 sda 32699 26992 2388388 52799 10467 63502 547260 105553 0 106377 160857 0 0 0 0 1293 2504

source:

xfce4-hardware-monitor-plugin/src/monitor-impls.cpp

Lines 1270 to 1279 in a7763c1

 // Splitting out device stats into individual fields 

 if (!split_stats_regex->match(single_dev_stats, match_info)) 

 { 

 // Unable to parse the device stats - warning user and moving on 

 std::cerr << Glib::ustring::compose("Unable to parse device stats line " 

 "from '%1' - regex match failure:\n" 

 "\n%2\n", "/proc/diskstats", 

 single_device_stats); 

 continue; 

 }

abandoned in favor of multiload-ng

problem:
xfce4-hardware-monitor-plugin depends on old and buggy libraries, like libgnomecanvas
OmegaPhil/hardware-monitor-applet#5

solution:
moving on to
https://github.com/udda/multiload-ng
