eG Monitoring
 

Measures reported by PROCURUpTimeTest

In large network environments, it is essential to monitor the uptime of the HP Procurve switch in the infrastructure. By tracking the uptime of the target switch, administrators can determine what percentage of time the switch 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 their switch. By knowing that the switch has been up for an unusually long time, an administrator may come to know that the scheduled reboot task is not working on a switch.

This test included in the eG agent monitors the uptime of the target switch.

Outputs of the test : One set of results for the target switch that is being monitored.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Reboot Indicates whether the switch has been rebooted during the last measurement period or not.   The values that this measure can report and the numeric values they indicate have been listed in the table below:

Measure Value Numeric Value
No 0
Yes 1

Note:

By default, this measure can report the Measure Values mentioned above while indicating whether the switch is rebooted or not. However, the graph of this measure is indicated using the numeric equivalents.
Uptime Indicates the time period that the switch has been up during the last measurement period. Seconds If the switch 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 switch 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 switch 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 switch has been up since its last reboot. Minutes Administrators may wish to be alerted if a switch has been running without a reboot for a very long period. Setting a threshold for this metric allows administrators to determine such conditions.
