Description: Manages command server operations and task execution on BlueCat Networks DNS/DHCP appliances.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is BCN-COMMANDSERVER-MIB?

BCN-COMMANDSERVER-MIB is a vendor-specific SNMP module from BlueCat Networks for monitoring the COMMANDSERVER service on BlueCat DNS/DHCP/IPAM appliances, which handles remote command/configuration execution on the appliance. It exposes the service's operational state along with alarm severity and alarm information objects, and defines a notification group for raising traps when service problems occur. This is a software-service status/fault MIB: bcnCommandServerSerOperState reports whether the command server process is up, down, or degraded, while bcnCommandServerAlarmSeverity/bcnCommandServerAlarmInfo provide fault detail useful for detecting a stalled or crashed management service on the appliance. It relies on the standard SNMP NOTIFICATION-TYPE framework for delivering bcnCommandServerNotification events with accompanying bcnCommandServerNotificationEvents/Data. Typical deployment context is enterprise or service-provider DNS/DHCP infrastructure using BlueCat Address Manager/DNS/DHCP Server appliances, monitored centrally for service health, with administrators able to find a BCN-COMMANDSERVER-MIB download available to load directly into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in BCN-COMMANDSERVER-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

BlueCat Networks DNS/DHCP/IPAM appliance

Monitoring Examples

An administrator would poll bcnCommandServerSerOperState to confirm the command server process is running normally on a BlueCat appliance, and check bcnCommandServerAlarmSeverity for an elevated severity indicating a fault. Receiving a bcnCommandServerNotification trap with bcnCommandServerNotificationEvents/Data populated would alert the NMS to a specific service disruption, such as the command server becoming unresponsive. A sustained non-normal bcnCommandServerSerOperState combined with a high bcnCommandServerAlarmSeverity would prompt investigation into whether the appliance needs a service restart.

How to Use in IPNetwork Monitor

Example using bcnCommandServerSerOperState OID:

Select a BlueCat Networks DNS/DHCP/IPAM appliance as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type bcnCommandServerSerOperState into the Find box to locate it in the OID tree, then select it and click OK. The operational state of this service — running, notRunning (stopped), starting, stopping, or fault. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is an INTEGER-type OID, Value bounds is the most useful condition here — trigger an alert if the value is 'fault', or it stays in 'starting'/'stopping' longer than a normal transition takes. Click Finish to create the monitor; you can adjust any parameter later.

OIDs

OID symbolic	OID numeric	Type	Access	Description
bcnCommandServer	1.3.6.1.4.1.13315.3.1.7
bcnCommandServerMIB	1.3.6.1.4.1.13315.3.1.7.1			This module provides status as well as statistical information about the COMMANDSERVER service.
bcnCommandServerObjects	1.3.6.1.4.1.13315.3.1.7.2
bcnCommandServerServiceStatus	1.3.6.1.4.1.13315.3.1.7.2.1			General state of the COMMANDSERVER Service.
INT bcnCommandServerSerOperStateEx	1.3.6.1.4.1.13315.3.1.7.2.1.1	INTEGER	read-only	Operational state of the Service. The possible states are: running(1) The service is running normally. notRunning(2) The service is stopped either intentionally (i.e.: the service is not supposed to run on this node) or unintentionally (a problem has occurred). starting(3) The service is in the process of starting, either for the first time of after an event occurred. stopping(4) The service is in the process of stopping. Stopping a service might be necessary after a configuration change. fault(5) An error has been detected and the state is undefined.
bcnCommandServerNotification	1.3.6.1.4.1.13315.3.1.7.3
bcnCommandServerNotificationEvents	1.3.6.1.4.1.13315.3.1.7.3.0
NTF bcnCommandServerAlarmNotif	1.3.6.1.4.1.13315.3.1.7.3.0.1			A bcnCommandServerAlarmNotif signifies that the COMMANDSERVER service has transitioned state or a particular event has been detected on the service.
bcnCommandServerNotificationData	1.3.6.1.4.1.13315.3.1.7.3.1
BCN bcnCommandServerAlarmSeverity	1.3.6.1.4.1.13315.3.1.7.3.1.1	BcnAlarmSeverity	accessible-for-notify	Severity classification for the alarm.
