Figure:
System overview - a distributed system
Description of the panel
The structure and the functionality of the system
overview panel is basically the same like the system overview
panel in a single system (see also System
overview in single systems). The created distributed systems
are shown on single tabs and the system names are shown as titles
on the tabs. If systems are added at runtime, these systems are
established dynamically in the system overview and the specific
tabs are shownautomatically (if the connection exists).
Furthermore (contrary to a single system) there
is the table Dist where
all Dist Managers and their statuses are shown.
Note
The action panel that is opened by clicking
the single archives (see also Swap
out/backup archives) can only be opened for the archives on
the own system (e.g. when the UI
from which the system overview panel was opened runs on the system
"dist_1" the actions panel of the archives can only
be opened on the "dist_1" tab via click on the archives!
The status bar in the lowest part of the system
overview panel displays the current user, date, time as well as
details on the user interface the panel was opened with. In the
figure above the details on the UI
show the following line:
Windows User Interface
#1 (EIWRK234), dist_1:
#1: is the number of the
UI.
(EIWRK234): corresponds to the display
the UI is running on.
dist_1: is the system name
the UI was started on.
In a redundant distributed system where the redundant
system is in the split mode additionally the computer on which
the UI was currently switched,
is shown (e.g. the following entry):
Windows User Interface
#1 (EIWRK234), dist_1: Eiwrk028
Note
This entry is shown in the status bar only
when the system overview panel was opened from a UI
that runs on one of the redundant computers!
See chapter Redundancy
in split mode of the redundancy documentation for further
information on the split mode.
Configuration of the error
weighting
CAUTION
Open the panel for the configuration of the
error weighting once and click on OK so that the error state is
shown correctly.
The table Error
state on the right side of the system overview panel shows
the error status on a specific system. The configuration of the
error weighting via the available panels is described in detail
in the chapter System
overview in single systems.
If you open this panel on a foreign system (this
means you switch in the system overview panel to a tab that shows
a foreign system - in the figure System
overview - a distributed system this would be the system "dist_2"
since the UI the overview panel
was opened from runs on system "dist_1" and the "dist_1"
is the local system) this is also shown on the Manager tab in the combo box
used for selecting the alert class with the name Foreign system!
Contrary to the configuration of the error weighting
in a single system there is a third tab Distributed
Connections for distributed systems. The weighting of the
connection to other systems, which are linked together with a
dist manager in a distributed project, is configured on this tab.
Caution
On a foreign system only existing settings for
the monitoring of managers or Dist connections can be changed
but new managers or Dist connections for the error weighting cannot
be added (the internal data point for the monitoring is not created
on a foreign system)!
Figure: Configuration panel for
the weighting - "Distributed Connections"
tab
The configured weightings are visible in the table
Connection (the system name, system number and the weighting are
shown on each row). You can change the settings of defined connection
by selecting it or add a new connection with the desired settings
to the table. In case of errors e.g. Dist Manager on system dist_2 fails, the configured
weighting is included in the calculation of the error status.
The settings that you can create in the lower part of this panel
(Append/Update) are same as the
settings that can be configured on the Manager tab of this panel.
Instead of selecting the manager you select the system to which
there is an existing connection and that should be monitored.
See chapter System
overview in single systems for details on the settings. Additionally
there is the check box System is redundant,
where you can define whether the system, which connection should
be monitored, is a redundant configured system (this make sense,
when the system was connected once and the current state cannot
be retrieved).
Example:
How to add a system with a weighting
Create your settings as shown in the figure above
(Distributed Connections tab).
Choose the desired system
from the combo box (e.g. dist_2).
Assign the weighting 250
to the system dist_2.
Configure an alert handling
with alert class in order to display an alert in the alert
panel in case of errors.
Activate the check box Monitor
redundant network (the dist managers are provided
with a redundant network connection in this example).
After creating the settings
click on the corresponding buttons to apply the settings in
the table. Selected entries in the table can also be deleted
(see Default
buttons on configuration panels).
After executing the steps of the examples described
earlier (adding a system with a weighting) and an error occurs
(the Dist Manager on the system 1 looses the connection to system
2) the table Error
state on the tab for the system 1 (dist_1) in the
system overview panel looks as follows:
In the table Error state
"Dist connection" + "System
name (if known)" + "System number (in parenthesis)"
is shown if a dist connection fails and this is configured with
a weighting.
All error statuses/weightings are summed and shown
at the top (250/542 - 250 is the sum of the weightings for all
upcoming errors and 542 is the sum of all configured weightings).
In the table below you see the single errors on the specific computer
with the set weighting. On the tab for the system 2 (dist_2) in
the system overview panel a figure and the text "Missing
connection" are shown. |
