Note1: The changed settings do not come into effect until after the next run of the collector. In other
words, the SA Host reads the configuration file after it has finished collecting for that day and it only
runs once every day. So, if the user changes the run time the following are possible scenarios:
Note 2: It is
recommended
that only one
instance of
NSA be run for
a given node,
because
multiple
instances may
cause conflicts
in the
$Volume used
for the Store
Volume. For
example, if two
or more
instances of
NSA are set
up to create
data files in
same location
($.SAYYMMDD), the SA collector that is scheduled first will be the owner of the daily data files.
This may result in inconsistent data (i.e. multiple snapshots of the same data) or file security issues.
