Measures reported by MariaEvtStgTest
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 MariaEvtStgTest 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.
Outputs of the test : One set of results for the Maria database server being monitored.

Interpretation |
| 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. |
| 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 timestamp at which the event was started, the timestamp at which the event was ended and the name of the source. |
| Total_events |
Indicates the total number of events executed in the database server. |
Number |
|
| 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_pct |
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. |
