Starting with V10.1 Fix Pack 1, the details_xml monitor
element has been deprecated. This monitor element might be removed
from the output of the system event monitor in a future release.
Details
When the EVENT_SCSTATS and EVENT_WLSTATS
logical data groups are included in the output of the statistics event
monitor, the
details_xml monitor element is included
as part of the output. This monitor element is an XML document that
contains other monitor elements that report system metrics information.
The elements that appear in this XML document are also included in
an XML document associated with the new
metrics monitor
element. The
metrics element is included in the
same two logical data groups (EVENT_SCSTATS and EVENT_WLSTATS). However,
unlike the metrics collected in the
details_xml document
which are accumulated values that start at database activation and
increase until database deactivation, the metrics in the
metrics XML
document show the change in value for a metric since the last time
statistics were collected. For more information, see
FP1: New XML document stores metrics collected by statistics event monitor.
In addition, two new logical data
groups, EVENT_SCMETRICS and EVENT_WLMETRICS are added to the statistics
event monitor. With these new logical data groups, you can now view
the information contained in the metrics monitor
element as individual elements without the need to parse an XML document.
For more information, see FP1: New logical data groups added to the statistics event monitor.
Resolution
If you use the XML metrics data
returned in the details_xml monitor element,
start using the metrics monitor element
instead. Alternatively, if you include the logical data groups EVENT_SCMETRICS
and EVENT_WLMETRICS in the information collected by the event monitor,
then you can access the metrics monitor elements directly. For example,
if you create a statistics event monitor that writes to tables, include
these two logical data groups, then you can access the metrics monitor
elements from the new tables associated with each of these groups.
