If the system heartbeat is disabled, or if you are not running Service Pack 4 or greater,
Uptime may report that the event logs do not contain sufficient information to calculate
system availability. This is because Uptime detects an abnormal shutdown (for instance a
bluescreen or power failure) but cannot determine how long the system was down during
this abnormal outage.
• No special privileges are required for basic operation although it is most accurate to run
Uptime under an administrative account, since much more information is available to
calculate system uptime and availability. For instance the time zone of the system is
important to many of the calculations, but this information can only be reliably obtained
by an administrator.
Additionally, when calculating the Current System Uptime, this tool attempts to use the
System Performance Counter for Uptime. However, if the user is not an administrator, this
counter may be unavailable. In this case an estimate is made based on the last recorded
boot noted in the event log.
• Application Failure event detection is dependent upon Dr Watson being enabled.
• Bluescreen detection is dependent upon the system being configured to write an event to
the event log if the system stops unexpectedly.
To enable bluescreen event logging for Windows NT 4.0 systems:
• Go to the Windows Control Panel and double-click the System Icon.
• Select the Startup/Shutdown tab.
• Select the
Write an event to the system log check box.
To enable bluescreen event logging for Windows 2000 Systems:
• Go to the Windows Control Panel and double-click the System Icon.
• Select the Advanced tab.
• From the Advanced property sheet select the Startup and Recovery button.
• Select the
Write an event to the system log check box.
