Maria Uptime Test

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

This Maria Uptime test monitors the uptime of the target Maria database instance.

Target of the test : A Maria Database server

Agent deploying the test : An internal/remote agent

Outputs of the test : One set of results for every Maria Database server being monitored.

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed.

Host

The IP address of the Maria Database server.

Port

The port on which the server is listening

Database

Specify the name of the database that is to be monitored on the target Maria Database server

User and Password

The eG agent has to be configured with the credentials of a user who has server-wide process and select privileges on the monitored Maria Database server. To know how to create such a user, refer to Configuring the eG Agent with Access Privileges section.

Confirm Password

Confirm the password by retyping it here.

ReportManagerTime

By default, this flag is set to Yes, indicating that, by default, the detailed diagnosis of this test, if enabled, will report the shutdown and reboot times of the device in the manager’s time zone. If this flag is set to No, then the shutdown and reboot times are shown in the time zone of the system where the agent is running(i.e., the system being managed for agent-based monitoring, and the system on which the remote agent is running - for agentless monitoring).

Detailed Diagnosis

To make diagnosis more efficient and accurate, the eG Enterprise suite embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option.

The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled:

  • The eG manager license should allow the detailed diagnosis capability
  • Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.
Measurements made by the test
Measurement Description Measurement Unit Interpretation

Has server restarted?

Indicates whether the database instance has been rebooted during the last measurement period or not.

 

If the value of this measure is Yes, it means that the database instance 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 database instance was rebooted. The Detailed Diagnosis of this measure, if enabled, lists the TIME, SHUTDOWN DATE, RESTART DATE, SHUTDOWN DURATION, and IS MAINTENANCE.

Uptime since last measure

Indicates the time period that the database instance has been up since the last time this test ran.

Secs

If the database instance 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 instance 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 instance 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.

Uptime

Indicates the total time that the database instance 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 instance has been running without a reboot for a very long period. Setting a threshold for this metric allows administrators to determine such conditions.
