window allows you to change the retention period of data received from Flow
Sources, along with an indicator showing the average data per day used per Flow
Source, and the estimated storage required based on the values entered.
average data/day is based on data over the last week. If there is less than a
week's worth of data, the actual duration of data will be displayed in
parenthesis, eg (three hours), so that you have an idea of how representative the
value will be.
are two different retention periods:
Summary Retention Period: How long the Opsview Monitor system should
retain summary data, i.e. rounded up, summarised values as opposed to the per second/minute data
files initially received. This data is stored within the ‘opsview_netflow_stats’
table in the Runtime database on the Opsview Monitor master server.
Full Data Retention Period: How
long the Opsview Monitor system should retain the ‘raw’ data, i.e. the files
within /var/opt/opsview/netflow that contain the per second/minute data.
