Viewing system availability

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:
  1. (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.
  2. (Linux only) On managed systems where compression of message logs is the default, turn off compression of message logs to view system-availability reports.
  3. System Availability reads the message logs only if the message logs are in their default directory.
  4. 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 View > Availability Report.

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 View > Detach View. 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 File > Print.
