ITLogBook supports three different kinds of filters that can be combined:
· Loglevel filters: filter logmessages by their Loglevel combinations. See Loglevel filter toolbar.
· Time filters: filter logmessages by their timestamp (used to display logmessages within a time interval). See Time filter toolbar.
· Custom filters: filter logmessages by their Module/Case combinations and logmessage text (using a substring search). More about that is explained in a separate topic about Custom filters.
Important:
Custom filter, Loglevel filter and time filter work additive.
Examples
The application of these filter kinds is shown by the following examples.
Example 1:
If you only want to view error and alarm logmessages (logmessages that have the error or alarm Loglevel (bit)), you need a Loglevel filter:
· Make sure the error and alarm level buttons of the Loglevel filter toolbar are pressed (sunken).
· Make sure the or operator of this toolbar is pressed (sunken).
Example 2:
If you want to hide all logmessages before a certain date and time, you need a time filter:
· Edit the begin-date and begin-time fields of the time filter toolbar.
· Make sure the Begin button of this toolbar is pressed (sunken)
If you want to hide all logmessage after a certain date and time, do the same with the end-date and end-time fields and the End button of the Time filter toolbar.
Example 3:
If you want to view all logmessages with a certain Module and Case combination and a special substring within their logmessage text, you need a Custom filter:
· Create a Custom AND-filter in the filterset pane under Custom Filters.
· Activate this filter by dragging it to the logmessage pane.
