19 – Configuring Extended Event Archiving
388 R400
Maximum Tolerable
Time Delay Between
Collections (minutes)
Used when the archiving system is enabled after being
disabled for some period of time. If extended event archiving
system has been disabled for less than the value specified in
the maximum tolerable time delay between collections, then it
does not lose any events that have occurred while it has been
disabled; it reads the records from the last event collected up
to the current push record. If extended event archiving has
been disabled for longer than the maximum tolerable time
delay between collections, then the events that occurred since
it was disabled are not read into the archiving system; it reads
from the current push record onwards.
The time of last collection and the current time are used to
check the delay period. Therefore, if the system has had a time
change greater than this setting, these events are not collected
even if extended event archiving is enabled.
The maximum tolerable time delay should be set to
approximately the time that it would take to fill the system file
with events. The number of records in the system file is shown
as the Maximum Standard Events parameter.
This is how the archiving system determines if the events in
the system file are valid or have been overwritten by events
that occurred while the archiving system was disabled. For
example:
Maximum Standard Events: 32,000
Time taken to collect events: 8 days (11,520 mins)
Extended Event
collection will not occur
if free disk space falls
below
The amount of disk space that must be free for extended event
archiving to operate. If free disk space falls below this value,
then the system stops collecting events, the status of the
archiving system changes to “Full Disk”, and a disk space error
alarm is generated. This value ensures that the Extended Event
Archiving system won’t take up all the disk space and prevent
the operating system from working.
Tape Save Action Select whether to add events after existing data on the archive
tape, or to replace existing data from the start of the tape.
