2. Project Summary
2.1. Project Description:
GKrellM, GNU (or Gtk) Krell Monitors (or Meters), is a single process
stack of system monitors which supports applying themes to match its
appearance to your window manager, Gtk, or any other theme. The current
version is 2.3.1
2.2. Risks and Assumptions:
1. Temperature, fan, and voltage sensor monitors not support since missing
libsensors.
2. APM laptop battery meter not support since no APM.
3. This application will depend on libgtop, which isn't engineered to fully
or best support Solaris interfaces for getting system information because
it was written from a more Linux perspective on system resources, and
some
system information can't get since not fully support from kernel, e.g.
some sensor monitor interfaces.
3. Business Summary
3.1. Problem Area:
GKrell is a computer program based on the GTK+ toolkit that creates a
single process stack of system monitors. It can be used to monitor the
status of CPUs, main memory, hard disks, network interfaces, local and
remote mailboxes, and many other things. Plugin is supported.
3.2. Market/Requester:
JDS Desktop group
3.3. Business Justification:
For many users, it's nice to be able to see, real-time, what is happening
on their system. There are ways to display memory usage, cpu usage,
network
traffic, available and used disk space, and a whole lot of other similar
system statistics. This makes it easier to troubleshoot and notice
problems
as they come up. To be display these monitors, you will need gkrellm.
It's a very useful monitoring tool, can replace a lots of the dock
applets, what's even better is that gkrellm supports a plugin interface,
allowing vast expandability, it's also infinitely configurable and
themeable.
Additionally Gkrellm is very easy on the CPU and packs a lot of
information
into a little bit of space.
3.4. Competitive Analysis:
Windows XP has SysMetrix, Windows Vista has this type of side bar,
and GKrellM can run in Linux and other Unix-like operating systems.
3.5. Opportunity Window/Exposure:
It is expected that this project will be integrated into Nevada B100
Note: this tool has GPL V3 license, it will not integrated into
Nevada until the license issue is solved.
3.6. How will you know when you are done?:
When it is ported to Nevada and runs correctly.
The project will be complete when there are no stoppers, P1 or P2 bugs.
4. Technical Description:
4.1. Details:
GKrellM is a GTK-based stacked monitor program that charts SMP CPUs,
disks, load, active net interfaces, and internet connections. There are
also builtin monitors for memory and swap, file systems with mount/umount
feature, mailbox checking including POP3 and IMAP, clock/calendar, laptop
battery, sensors (temperatures, voltages, and fans), and uptime. It has
LEDs for the net monitors and an on/off button and online timer for PPP.
Multiple monitors managed by a single process to reduce system load.
There is a GUI popup for configuration, plugin extensions can be
installed,
and many themes are available. It also features a client/server
monitoring
capability.
If you want to configure GkrellM, you can right-click on the monitor and
select Configuration from the drop-down menu, or press the F1 key at
anytime while GKrellM has the focus. The configuration menu lets you
modify general options, built-in monitors, plug-ins, and themes.
GKrellM consists of the gkrellm client and the gkrellmd server. Gkrellm
can
run in client mode and collect data from gkrellmd server running on a
remote
machine. In this way, the user can remotely monitor different
characteristics
of all the machines on their LAN, such as hits and load on the web
server,
disk usage on the mail server, and port traffic on the NAT.
The gkrellm client gets data from gkrellmd through SSH. By default
gkrellmd
will not run by default, so the user need to start gkrellmd manually,
and optionally add options to configure gkrellmd. For example,
you can configure which port gkrellmd will use and which IP addresses or
hostnames are allowed to connect to gkrellmd. gkrellm client will also
be
configured to use some port, this port is used to create the SSH
connection
with the gkrellmd server given port. Then you can start gkrellm on
another
system and get the remote data from gkrellmd.
4.2. Bug/RFE Number(s):
RFE 6732524
4.3. In Scope:
The system information we can get from Solaris
4.4. Out of Scope:
The system information Solaris can't support, e.g. temperature.
All plugins that are installed by users themselves.
