tkping — network monitoring tool
tkping is intended primarily for system administrators and network
administrators so that they can see when crucial hosts and other
network nodes go down.
tkping is typically left running for days. The user can see all nodes
are green meaning that all are OK. After being away from the display
for a period of time, the user returns and looks at the display. If
any of the nodes are not green, then the user knows that those have
either "gone missing" for a short period of time or have rebooted (The
color tells the user which). Either way, the user knows to log onto
these machines to see what happened or to look into the status of the
network/subnet to which the failing machines are connected. Overall,
this saves the user time, as there is no reason to check into the
health of the machines which remain green.
DETAILS OF OPERATION
tkping is a tool that runs under the X Window System to display the
status of internet nodes.
tkping displays a grid of node buttons, one for each node being
monitored. The name of the node represented by the button is displayed
on the face of the button.
This grid can be laid-out automatically by tkping or the layout can be
controlled by the user from the command-line or by settings in a
control file (See: -rows, -columns).
tkping also supports additional layout control interspersed within the
nodes file. (See: <blank>, <message>, and <nextcolumn>.)
At specified intervals, tkping will generate a number of ICMP echo
packets (similar to the ping(8) program) and send them to each of the
specified nodes. tkping displays the results of its pings by coloring
the button associated with the node based on the status of the returned
The grid of buttons supports a couple styles of interaction. The user
may select a menu operation affecting all of the nodes, or the user may
click on one or more buttons and then select a menu operation which
affects only those selected. Finally, a right-click operation on a
button is supported. This pops up a list of operations one can do
against that specific button.
The button color represents current status of the node. The user can
recheck a node, mark it a down, or get info regarding details of the
history of ping attempts against this node.
To recheck a node, simply click on the button corresponding to the
desired node. The color will change, indicating that the node has been
selected. Picking ‘‘Recheck’’ from the menu will then check the node
again. During the time that a node is being rechecked, the cursor will
change to an hourglass. All button and/or keypress events sent to
tkping will be ignored until the pinging is complete and the cursor is
If a node is selected and ‘‘Down’’ is picked, then the node is marked
as ignored and the color of the button is changed to represent this
status. When tkping next traverses the grid, this node will not be
checked. This is useful when the user knows a node to be down and does
not want to waste any time checking it.
If a node is selected and ‘‘Info’’ is picked, a pop-up dialog will
display statistics about that node. Currently, tkping will print out
the total number of times the node returned none, some, or all of the
packets sent out, the total number of packets sent to and received from
the node, and the average packet round-trip time sampled over the last
5, 50, 100, and 200 grid traversals.
Multiple nodes may be rechecked, or marked as down. If ‘‘Info’’ is
then picked, only the first node will have its information displayed.
The following are the command-line arguments understood by tkping:
This option is used to specify the number of rows in the host
grid. Entries in the node file will then be loaded top to
bottom. (Resource name: rows).
This option is used to specify the number of columns in the
host grid. Entries in the node file will then be loaded left
to right. (Resource name: columns)
Specify the text to put on the application titlebar (as
opposed to the window manager’s titlebar). (the default is
‘‘tkping’’ followed by a version string). (Resource name:
Specify a name of a file which contains the hosts to put on
the grid. If this option is given, the default file
~/.tkpingrc will not be loaded. (No associated resource)
Name of the file which contains option settings. Use in
place of discrete command-line options, an X resources file,
or the system-wide defaults file /etc/tkping/tkping.conf.
(No associated resource)
Specifies the log file to which diagnostic output will be
Number of packets to send to each node (default 5).
(Resource name: numberPackets)
Interval between traversals of the grid (default 120
seconds). (Resource name: sleepDelay)
How long to wait for each packet before assuming the node is
not responding (default 0.5 seconds). (Resource name:
-ignore In certain circumstances, it may be preferable that tkping
not immediately attempt to ping all the nodes on the grid.
When this option is set, all nodes will act as though they
had been selected and the ‘‘Down’’ menu item picked.
-debug Turn on debugging. Used primarily by developer of tkping.
-verbose Show more detailed info regarding application state.
Show summary of options.
tkping uses colors to indicate the status of each node. The standard
color codes along with the X-default codes are as follows:
Host returned all packets sent.
Host returned some of the packets sent.
Host returned none of the packets sent.
The node is to be ignored.
The node changed its status from either returning no packets
or from an error to returning all packets. The cell will
remain in this color or pattern until reset by manually
checking the node (see above).
An internal error has occurred. This should only occur if
the host name cannot be found in either the name server or
system host table.
The text headings for groups of nodes (buttons) should be
displayed in this color.
File containing nodes to check as well as labels to display
amongst the node buttons.
File containing settings default values for timeouts, ping
