Maria Event Stages Test

Events are named database objects containing SQL statements that are to be executed at a later stage, either once off, or at regular intervals. Events are only executed if the event scheduler is running.

Administrators need to continuously track the status of events that are scheduled, so that they can always tell which events are running as per schedule and which scheduled events are still waiting. The Maria Event Stages test helps in this regard. This test monitors pre-configured tasks at periodic intervals and reports the count of tasks in various stages of progress. To determine which tasks are in what state currently, use the detailed diagnosis of the test.

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 the database 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

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

Total events

Indicates the total number of events executed in the database server.

Number

 

Running events

Indicates the number of events that were running during the last measurement period.

Number

The detailed diagnosis of this measure lists the thread ID, the event ID, the name of the event, the time stamp at which the event was started, the time stamp at which the event was ended and the name of the source.

Completed events

Indicates the number of events that were completed during the last measurement period.

Number

 

Nested events

Indicates the number of events that were waiting for the same resource used by another event.

Number

The detailed diagnosis of this measure lists the thread ID, the event ID, the name of the event, the time stamp at which the event was started, the time stamp at which the event was ended and the name of the source.

Waited events

Indicates the number of events that were in wait state during the last measurement period.

Number

The detailed diagnosis of this measure lists the thread ID, the event ID, the name of the event, the time stamp at which the event was started, the time stamp at which the event was ended and the name of the source.

Waited events percentage

Indicates the percentage of events that were in wait state.

Percentage

A value close to 100 indicates that the events executing on the database are in wait state. This may be due to a performance bottleneck or connection errors.
