This topic describes how to start the System Availability task
in IBM Director.
In the IBM Director Console Tasks pane, drag the System Availability task
onto a managed system or group that supports System Availability.
The
list on the toolbar in the System Availability window has four options:
- Distribution of System Outages
- A pie chart representing the percentage of all system outages.
- Distribution of System Uptime
- A pie chart representing the percentage of all system uptime.
- System Outages by Day of Week
- A bar chart measuring the frequency of outages by day of the week, with
planned and unplanned outages differentiated.
- System Outages by Hour of Day
- A bar chart measuring the frequency of outages by hour of the day, with
planned and unplanned outages differentiated.
To see the value of a specific pie chart or bar chart section,
move the cursor over a specific section.
Notes: - (Windows operating systems that support IBM Director and are configured
to adjust automatically for daylight saving time only ) The event times that
are specified in the system-availability report might vary by 1 hour from
the event times in the Windows event viewer, because the Windows event viewer
adds or subtracts one hour to adjust for daylight saving time. Because this
adjustment can cause duplicate entries in the system-availability database
when the time adjustment is made, System Availability does not use the daylight
saving time adjustments.
- (Linux only) On managed systems where compression of message logs is the
default, turn off compression of message logs to view system-availability
reports.
- System Availability reads the message logs only if the message logs are
in their default directory.
- System Availability should run as or more often than the message logs
are archived to avoid losing availability information.
The availability report is a snapshot of system availability.
It provides an overall statistical summary of event and problematic details
and measurements for the currently selected managed systems in a tree structure,
or all managed systems if the root of the tree is selected. Systems identified
as problematic are listed in the detail section and are flagged with a red
X. There are two types of reports that you can view by following these steps:
To
view the availability report, click .
To
view a more detailed view of the availability report, right-click the graph,
and then click Detailed List of Record.
In
the System Availability window, you can detach the current view to compare
and contrast different system-availability views and time frames. Click .
The current view is separated as an independent window that does not reflect
subsequent changes to the report. Closing the System Availability task closes
any detached view windows.
With the exception of a detached view, you
can print any window that is displayed in the System Availability task by
clicking .
