eG Monitoring
 

Measures reported by CouchDBUpTimeTest

In most production environments, it is essential to monitor the uptime of critical servers in the infrastructure. By tracking the uptime of each of the servers, administrators can determine what percentage of time a server 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 servers. By knowing that a specific server has been up for an unusually long time, an administrator may come to know that the scheduled reboot task is not working on a server.

This test included in the eG agent monitors the uptime of the target Apache CouchDB server.

Outputs of the test : One set of results for the target Apache CouchDB Server.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
uptime Indicates the total time that the database server has been up since its last reboot. Minutes This measure displays the number of years, months, days, hours, minutes and seconds since the last reboot.

Administrators may wish to be alerted if the database server has been running without a reboot for a very long period. Setting a threshold for this metric allows administrators to determine such conditions.
upTime_Seconds Indicates the time period that the database server has been up since the last time this test ran. Seconds If the database server 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 database server 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 database server 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.
isRebooted Indicates whether the database server has been rebooted during the last measurement period or not.   The values reported by this measure and its numeric equivalents are mentioned in the table below:

Measure Value Numeric Value
Yes 1
No 0


Note:

By default, this measure reports the Measure Values listed in the table above to indicate whether the database server has been rebooted during the last measurement period or not.

If the value of this measure is 1, it means that the database server was rebooted during the last measurement period. By checking the time periods when this metric changes from 0 to 1, an administrator can determine the times when this database server was rebooted.

Use the detailed diagnosis of this measure to figure out the Time, Shutdown Date, Restart Date, Shutdown Duration, and Is Maintenance details.
