In this menu you can find or create a list for passing traps to monitoring process. Trap Filters are used for determining if traps received by SONARPLEX will be passed to monitoring process or blocked otherwise.
Filters are defined by human readable name, source address, Object Identifier (OID) and resulting service state.
To edit or create a new or existing trap filter, proceed as follows:
- Open the Administration Web Interface > Configuration > Host Checks and select a command name for host checks (see picture below).
Enter your settings or changes, as described in the table below.
