When monitoring BDDS using SNMP, BlueCat recommends polling the
following SNMP Objects to monitor the health of the system.
BlueCat SNMP MIBs
Each BlueCat-specific
BDDS MIB (management information base) OID (object
identifier) begins with the following prefix of network management object
identifiers:
.1.3.6.1.4.1.13315
That represent
iso.org.dod.internet.private.enterprise.bluecatnetworks.
Note: The
following tables are not an exhaustive list of available SNMP MIBs. For more
information of all SNMP MIBs available in BDDS, refer to
DNS/DHCP Server polled objects
