Measures reported by ZoneUptimeTest

This test monitors the uptime of every zone on a Solaris virtual server.

Measurement Description Measurement Unit Interpretation
Rebooted Indicates whether the zone has been rebooted during the last measurement period or not   If the value of this measure is Yes, it means that the server was rebooted during the last measurement period. By checking the time periods when this metric changes from No to Yes, an administrator can determine the times when this server was rebooted. The Detailed Diagnosis of this measure, if enabled, lists the TIME, SHUTDOWN DATE, REBOOT DATE, SHUTDOWN DURATION, and IS MAINTENANCE.
Uptime Indicates the time period that the zone has been up since the last time this test ran. Secs If the zone has not been rebooted during the last measurement period and the agent has been running continuously, this value will be equal to the measurement period. If the zone was rebooted during the last measurement period, this value will be less than the measurement period of the test. For example, if the measurement period is 300 secs, and if the zone was rebooted 120 secs back, this metric will report a value of 120 seconds. The accuracy of this metric is dependent on the measurement period - the smaller the measurement period, greater the accuracy.  
Total_uptime Indicates the total time that the zone has been up since its last reboot.   This measure displays the number of years, months, days, hours, minutes and seconds since the last reboot. Administrators may wish to be alerted if a zone has been running without a reboot for a very long period. Setting a threshold for this metric allows administrators to determine such conditions.  

Note:

If a value less than a minute is configured as the TEST PERIOD of the ZoneUptime test, then, the Uptime measure will report the value 0 for the zones until the minute boundary is crossed. For instance, if you configure the ZoneUptime test to run every 10 seconds, then, for the first 5 test execution cycles (i.e., 10 x 5 = 50 seconds), the Uptime measure will report the value 0 for all zones; however, the sixth time the test executes (i.e., when test execution touches the 1 minute boundary), this measure will report the value 60 seconds for the zones. Thereafter, every sixth measurement period will report 60 seconds as the uptime of the zones. This is because, Unix-based operating systems report uptime only in minutes and not in seconds.
