Creating Statistics Filters
Using the Launch Facility, you can set filters for each statistics window you open.
Normally, the Statistics Manager polls a router for the values of all MIB objects
defined in the active statistics window. The window then shows the values of those
objects, as determined by the data returned by the router. Filtering limits the
objects you view in the statistics window.
There are two types of filters:
• Display filters
• Retrieval filters
A display filter enables the Statistics Manager to search the contents of the active
statistics window and then show or hide the specified objects.
You can set the display filter to show or hide only those objects that contain a
string matching the filter string. Specifying a longer display filter string narrows
the number of possible matches in the active statistics window.
A retrieval filter enables the Statistics Manager to poll a router for only a subset of
MIB objects. These objects have instance IDs that match the full or partial
instance ID you enter in the Retrieval Filter window. Specifying a longer string for
the instance ID in the Retrieval Filter window causes the workstation to solicit a
smaller number of objects from a router.
The active statistics window displays the values of those objects you filtered, as
determined by the data returned by the polled router. The Statistics Manager polls
only one router in each statistics window.
