- SCO Host Resources MIB Support
-
- SCO OpenServer Release 5 includes support for the Host Resources
- MIB. This is an SNMP MIB, based on IETF RFC1514. This document
- describes what information is provided by SCO OpenServer Release
- 5 for each MIB entry.
-
- The Host Resources MIB defines a uniform set of objects useful
- for the management of host computers. Host computers are
- independent of the operating system, network services, or any
- software applications.
-
- The Host Resources MIB defines objects which are common across
- many computer system architectures.
-
- In addition, there are objects in the MIB-II which also provide
- host management functionality. Implementation of the System and
- Interfaces groups is mandatory for implementors of the Host
- Resources MIB. Implementations of the Host Resources MIB makes
- SCO systems manageable by SNMP management stations.
-
- The following sections list the definitions included in the HR
- MIB. The attributes are read-only unless noted otherwise.
-
-
- The Host Resources System Group
-
- hrSystemUptime - implemented
- hrSystemDate - implemented - attribute is writeable
- hrSystemInitialLoadDevice - implemented - attribute is writeable,
- but changes are not stored. Subsequent access will reset the value
- hrSystemInitialLoadParameters - implemented - attribute is writeable,
- but changes are not stored. Subsequent access will reset the values
- hrSystemNumUsers - implemented
- hrSystemProcesses - implemented
- hrSystemMaxProcesses - returns zero, as there is no fixed maximum
-
-
-
- The Host Resources Storage Group
-
- hrMemorySize - implemented
- hrStorageTable -implemented - includes streams buffers, swap areas,
- and filesystems
- hrStorageEntry
- hrStorageIndex - implemented
- hrStorageType - implemented
- hrStorageDescr - implemented
- hrStorageAllocationUnits - implemented - filesystems and swap space
- have fixed-size allocation units (1K blocks),
- Streams buffers vary in size
- hrStorageSize - implemented
- hrStorageUsed - implemented
- hrStorageAllocationFailures - implemented for streams buffers only.
- Other storage types always return zero
-
-
-
- The Host Resources Device Group
-
- hrDeviceTable -implemented - includes hard disks, floppy disks, CD-ROMs,
- tape drives, mice and other pointing devices, video displays,
- printers, networks, and processors
- hrDeviceEntry
- hrDeviceIndex - implemented
- hrDevicetype - implemented
- hrDeviceDescr - implemented
- hrDeviceID - returns 0.0 which means unknown
- hrDeviceStatus - varies for device type. Returns unknown in most cases.
- Returns running or down for processors. Returns down if a
- printer is not enabled.
- hrDeviceErrors - returns zero for all devices
- hrProcessorTable - this is potentially sparse, an entry only
- exists if the correspondent value of the hrDeviceType
- object is 'hrDeviceProcessor'
- hrProcessorTable
- hrProcessorEntry
- hrProcessorFrwID - returns 0.0 which means unknown
- hrProcessorLoad - implemented - it is implemented in such a way
- that it shows the average over the last 20 minutes, not
- the last 1 minute. Correct this by having cron(C) run
- sadc(ADM) every minute.
- hrNetwork Table
- hrNetworkEntry
- hrNetworkIfIndex - implemented
- hrPrinterTable
- hrPrinterEntry
- hrPrinterStatus - returns unknown
- hrPrinterDetectedErrorState - If the printer is enabled and
- accepting jobs, this attribute returns 0; otherwise
- it returns 2 (bit 6 --off-line)
- hrDiskStorageTable
- hrDiskStorageEntry
- hrDiskStorageAccess - implemented
- hrDiskStorageMedia - implemented
- hrDiskStorageRemovable - implemented
- hrDiskStorageCapacity - implemented
- hrPartitionTable
- hrPartitionEntry
- hrPartitionIndex - implemented
- hrPartitionLabel - implemented
- hrPartitionID - implemented
- hrPartitionSize - implemented
- hrPartitionFSIndex - implemented
-
-
-
- The File System Table
-
- hrFSTable
- hrFSEntry
- hrFSIndex - implemented
- hrFSMountPoint -implemented
- hrFSRemoteMountPoint - implemented
- hrFSType -implemented
- hrFSAccess -implemented
- hrFSBootable - implemented
- hrFSStorageIndex - implemented
- hrFSLastFullBackupDate - returns unknown
- hrFSLastPartialBackupDate - returns unknown
-
-
-
- The Host Resources Running Software Group
-
- This optional group is not implemented on SCO systems at this time.
-
-
- The Host Resources Running Software Performance Group
-
- This optional group is not implemented on SCO systems at this time.
-
-
- The Host Resources Installed Software Group
-
- This optional group is not implemented on SCO systems at this time.
