Each server and background process can write to an associated trace file in order to log messages and errors. Background processes and the ALERT file are written to the destination specified by BACKGROUND_DUMP_DEST.
Trace files for server processes are written to the destination specified by USER_DUMP_DEST.
This metric checks for available free space on these dump destination devices. If the space available is less than the threshold value given in the threshold arguments, then a warning or critical alert is generated.
The rest of the information in this section is only valid for this metric when it appears in either the Enterprise Manager Grid Control or the Enterprise Manager Database Control (if applicable).
The following table shows how often the metric's value is collected and compared against the default thresholds. The 'Consecutive Number of Occurrences Preceding Notification' column indicates the consecutive number of times the comparison against thresholds should hold TRUE before an alert is generated.

For this metric you can set different warning and critical threshold values for each "Type of Dump Area" object.
If warning or critical threshold values are currently set for any "Type of Dump Area" object, those thresholds can be viewed on the Metric Detail page for this metric.
To specify or change warning or critical threshold values for each "Type of Dump Area" object, use the Edit Thresholds page. See Editing Thresholds for information on accessing the Edit Thresholds page.
Calculated using the UNIX df –k
command.
Verify the device specified in the initialization parameters BACKGROUND_DUMP_DEST, USER_DUMP_DEST, and CORE_DUMP_DEST are set up properly for archiving.
If the BACKGROUND_DUMP_DEST, USER_DUMP_DEST, and CORE_DUMP_DEST initialization parameters are set up correctly and this metric triggers, then free up more space in the destination specified by the dump destination parameters.
