Figure 3: SNMP management structure in BS2000
NET-SNMP
NET-SNMP is supplied with BS2000 and contains the SNMP daemon snmpd, the SNMP trap daemon snmptrapd and the SNMP client tools (snmpwalk, snmpget and snmpset). The SNMP daemon also contains the functionality of both Event and Scheduling services.
The SNMP daemon is the BS2000 communication partner for the management station, which handles the SNMP protocol. It also controls the communication with the agents and offers access to diverse groups of the MIB-II (System,
The Event Services allows you to monitor MIB objects of other agents and perform simple actions, as soon as specific conditions (trigger tests) have been satisfied.
The Scheduling Services enables modifications to be made to objects periodically or at defined times.
SNMP-AGENTS
SNMP-AGENTS V1.1 includes a set of agents for BS2000-specific management tasks.
The Application Monitor agent monitors user applications, BCAM applications, tasks, job variables, BS2000 subsystems and the log files of BS2000, POSIX and NFS. DCAM applications, log files and subsystem states can be monitored cyclically. Logically associated objects in a business process can be grouped together by the Application Monitor agent and monitored either separately or as a group.
The Console Monitor agent is used for console monitoring. On the one hand, it allows you forward console messages as trap notifications and precisely define the quantity of the messages to be recorded. On the other, you can also issue BS2000 SDF commands from the management station and query the results.
The Host Resources agent supplies information about the host, devices, pubsets, file systems and the installed software and notifies changes.
The HSMS agent allows you to read and modify global HSMS data. It also supplies detailed information on HSMS tasks. The scope of the tasks can be restricted by the selection criteria "state" and "origin".
The openFT (BS2000) agent supplies information about FT system parameters and statistics of the session. It also has the additional functions of starting and stopping the FT, diagnosis control, generating new public keys for encryption and changing the status of an FT partner.
The performance monitoring agent openSM2 supplies real-time values of monitoring CPU utilization, I/O rates and memory consumption provided by the SM2 subsystem.
The openUTM agent offers the monitoring and control of selected UTM applications, e.g. information on UTM objects, modifying application properties and system parameters, or terminating an UTM application.
The agent for spool and print services monitors the SPOOL and RSO devices and supplies information about print jobs.
The agent for storage management supplies information about pubsets and disks. The agent is also able to monitor the state of the selected pubsets and disks.
The BCAM agent supplies information about NEA, ISO and TCP/IP protocols and represents them on the transport system.
The FTP agent supplies information related to data transfers based on the FTP protocol. It also allows controlling the local FTP daemons by changing their state and parameters.
The SESAM/SQL agent provides statistical information with regards to the available database handlers. It also provides the SESAM/SQL Performance Monitor measurements output.
