Systems Management MIB

The Systems Management MIB is a private-enterprise MIB that includes objects for monitoring the health and performance of the underlying system and its applications.

The groups and tables with objects that you can monitor in the Systems Management MIB are as follows:

System Group (sysedgeSystem)

Contains basic system information such as host name, CPU type, and operating system version.

Mounted Devices Table (devTable)

Contains information about devices and file systems mounted on the host. You can create monitors for values such as file system space or unmount a mounted device by setting a column value in this table.

Kernel Configuration Group (kernelConfig)

Contains kernel information such as number of CPUs, amount of virtual memory, and clock rate. You can monitor how the kernel is configured and the kernel version using this group.

Boot Configuration Group (bootconf)

Contains information about the root file system, dump file system, and swap space. Monitor this table to track values such as root file system name, file system blocks, and file system type.

Streams Group (streams)

Contains information about the streams I/O subsystem. You can monitor the health of the subsystem by monitoring objects in this group such as number of streams in use, number of stream allocation failures, and number of streams in queue.

User Table (userTable)

Contains information about the user accounts on the system.

Group Table (groupTable)

Contains information about the user groups on the system.

Process Table (processTable)

Contains information about running processes. You can monitor this table to track the processes that are currently running, and you can also control processes by setting certain attributes. For example, you can kill a process by setting the value of the processkill column to 9.

Who Table (whoTable)

Contains information about the users currently logged on to the system. You can monitor attributes in this table to track who is using a system at any particular time.

Remote Shell Group (remoteshell)

Contains attributes for running shell scripts and programs on the remote system. Set the attributes in this table to specify a command, its arguments, and the name of an output file.

Kernel Performance Group (kernelperf)

Contains information about the health and performance of the host operating system. You can monitor attributes such as the number of current processes and open files, the number of active jobs, and the number of jobs in the scheduler queue.

Interprocess Communication Tables (msgqueTable, shmemTable, semTable)

Contains information about message queues, shared memory, and semaphores in separate tables. Monitor these tables to coordinate communication between processes.

Message Buffers Allocation Table (mbufAllocTable)

Contains information about how your system is using message buffers. Monitor attributes in this table to track information such as the number of times buffer requests were denied or delayed.

Streams Buffers Allocation Table (strbufAllocTable)

Contains information about buffer allocation and usage statistics for buffers used by the Streams subsystem.

I/O Buffer Cache Group (ioBufferCache)

Contains information about I/O buffer allocation and usage for basic disk I/O. Monitor this table to track information such as peak periods of I/O buffer activity.

Directory Name Lookup Cache Group (dnlc)

Contains information about directory and file name cache performance.

AIX Logical Partition Group (logicalPartition)

Contains information about IBM AIX logical partitions (LPARs). You can monitor attributes such as physical or logical CPU for each partition and the number of CPUs for each partition.

Trap Community Table (trapCommunityTable)

Contains SNMP information such as configured communities, users, and trap destinations.

NT System Group (ntSystem)

Contains information specific to Windows systems. This group contains System, Thread, Registry, Service, System Performance, Cache Performance, Memory Performance, Page File Performance, and Event Monitor groups for monitoring attributes for these areas on Windows systems.

RPC Statistics Group (rpc)

Contains information about kernel remote procedure calls. Monitor this table to track attributes such as counters and statistics for detecting peak periods of RPC activity.

NFS Statistics Group (nfs)

Contains information about the kernel's NFS facility. Monitor this table to track attributes such as statistics and counters for detecting peak periods of NFS activity.

Disk Statistics Table (diskStatsTable)

Contains information about disk I/O.

CPU Statistics Table (cpuStatsTable)

Contains performance statistics for each CPU. You can monitor attributes such as time spent in Idle mode and time spent in Wait mode.

The Systems Management MIB also contains the monitoring tables and tables to support object aggregation.
