Measurement Unit |
Interpretation |
| Num_recent_errors |
Indicates the number of errors that were added to the alert log when the test was last executed. |
Number |
The value of this measure is a clear indicator of the number of “new” alerts that have come into the alert log of the monitored database. The detailed diagnosis capability, if enabled, lists the errors newly added to the Oracle alert log file. |
| File_size |
Indicates the current size of the alert log file. |
MB |
This measure will only be reported for the ‘Summary’ descriptor of this test. |
| Growth_rate |
Indicates the rate at which the alert log file is growing. |
MB/Sec |
This measure will only be reported for the ‘Summary’ descriptor of this test.
A high value for this measure or a consistent increase in its value indicates that the alert log is rapidly growing and may end up occupying too much space on the volume.
Under such circumstances, it is recommended that you delete the alert log file and then issue a log file switch, so that Oracle automatically creates a new alert log file for you the next time a database activity needs to be logged. |
