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 .

  • 1—Running
  • 2—Not Running
  • 3—Starting
  • 4—Stopping
  • 5—Fault
BCN-DNS-MIB.mib
SNMP Object OID Description
.bcnDnsSerOperState .3.1.2.2.1.1 Current running state of DNS service:

BlueCat also recommends monitoring BDDS for the following SNMP traps:

SNMP Object OID Description
.bcnDhcpv4AlarmNotif .3.1.1.3.0.1 Returns when the DHCPv4 service has transitioned state or a particular event has been detected on the service.
.bcnDnsAlarmNotif .3.1.2.3.0.1 Returns when the DNS service has transitioned state or a particular event has been detected on the service.
.bcnNtpAlarmNotif .3.1.4.3.0.1 Returns when the NTP service has transitioned state or a particular event has been detected on the service.
.bcnHaAlarmNotif .3.1.5.3.0.1 Returns when the xHA service has transitioned state or a particular event has been detected on the service.
.bcnCommandServerAlarmNotif .3.1.7.3.0.1 Returns when the Command Server service has transitioned state or a particular event has been detected on the service.
.bcnSysAlarmNotif .3.2.3.0.1 Returns when the system starts, reboots, or shuts down

Linux SNMP MIBs

You can also poll BDDS for the following Linux-specific SNMP Objects for information on system load and usage.

UCD-SNMP-MIB.mib
