eG Monitoring
 

Measures reported by CbrUptimeTest

In most production environments, it is essential to monitor the uptime of critical components such as the branch repeater in the infrastructure. By tracking the uptime of the branch repeater, administrators can determine what percentage of time the device has been up. Comparing this value with service level targets, administrators can determine the most trouble-prone areas of the infrastructure.

In some environments, administrators may schedule periodic reboots of the repeater. By knowing that the repeater has been up for an unusually long time, an administrator may come to know that the scheduled reboot task is not working.

The Uptime test included in the eG agent monitors the uptime of the branch repeater.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
reboot Indicates whether the device has been rebooted 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 branch repeater has been up since the last time this test ran. Secs If the branch repeater 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 branch repeater 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 branch repeater 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 branch repeater 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 branch repeater has been running without a reboot for a very long period. Setting a threshold for this metric allows administrators to determine such conditions.
