Control Frame @[HOSTS_TITLE] Hosts

The control frame is positioned above each of the tables with net test data to display. Its functionality is just similar for all of these tables. The frame contains the attributes described below.

Signal Applet.
This Applet is responsible for:
  1. To load the net test data from the Web server. This is automatically performed after initialization of the HTML page. The signal shows with a signal color the following phases during the loading of the data:
    Gray square.
    The Applet has still to be load by the browser.
    Red light.
    The net test data have to be load by the Applet.
    Yellow light (blinking).
    The net test data are being loaded by the Applet. The number of lines read are shown in the status bar of the browser. If the light does not blink the loading from the Web server is stalled.
    During the loading of the data, the bottom frame shows a blinking header "Loading data ...". Please note that Internet Explorer does not support blinking. In this browser it is also possible that the header is not shown at all. This is probably due to caching.
    Also due to caching browsers at Unix hosts using X windows, in general only the end states of the signal are visible. So often the (blinking) yellow is not shown at all at Unix hosts.
    Green light.
    The net test data are loaded in the browser.
  2. To show a plot window. It shows the table data with an XY plot.
  3. . See also the help page and the description of the button which can be used to open the plot window.
Static /Repeat.
This radio button can be used to toggle between:
Overview.
This button can be used to show the table with the overview of all net test data of all hosts at the most recent time and date in the current table.
Throughput.
This button can be used to show the table which contains the throughput values between one host and all others hosts, starting at the most recent time in the current table. If the current table is the load table, the last known value of the host, for which the tables with one of the net test data are displayed, is used.
Load.
This button can be used to show the table with the load values as a function of the time, starting at the most recent time in the current table.
Ping.
This button can be used to show the table with the roundtrip values between one host and all others hosts, starting at the most recent time in the current table. If the current table is the load table, the last known value of the host, for which the tables with one of the net test data are displayed, is used.
This button can be used to show the plot window which shows a graphical representation of the current table. At the overview table, the last known other table is displayed, or the load when no other table is used yet.
See also the help page of the plot window.
Scroll size (top row, second from right).
This select field can be used to set the scroll size in the table when a time is selected. The following scroll sizes can be set, entitled:
Scroll line (default)
Scroll a line forward or backward.
Scroll 1/2 table
Scroll half a table forward or backward.
Scroll table
Scroll a table forward (backward). The last (first) line is redisplayed after scrolling.
Time (input field at bottom row, second from right).
This input field displays the most recent time of the table results. The other results in the tables are shown with steps equal to the value of the timestep input field.
At the left side of this field in the lower row of the control frame, there are the following related buttons which can be used to change this field:
|<<
Go to the most recent time after reloading the net test data from the Web server.
<<
Go to the previous time (in the future) in the table, using the selected scroll size.
>>
Go to the next time (in the history), using the selected scroll size.
Timestep (bottom row, most right).
This select field can be used to set the timestep which is used to display successive values as a function of the time in the tables.
