34.Sh NAME
35.Nm snmp_hostres
36.Nd host resources module for
37.Xr bsnmpd 8
38.Sh LIBRARY
39.Pq begemotSnmpdModulePath."hostres" = "/usr/lib/snmp_hostres.so"
40.Sh DESCRIPTION
41The
42.Nm
43module implements the HOST-RESOURCES-MIB as standardized in RFC 2790.
44.Sh RESTRICTIONS
45Not all information in the MIB is meaningful in FreeBSD or is available.
46The following variables are not implemented or carry no information:
47.Bl -tag -width indent
48.It Va hrFSType
49There are several types of file systems for which no appropriate OID
50exists yet which are supported by
51.Fx .
52For smbfs, procfs and devfs ,
53.Va hrFSOther
54is returned.
55In all other cases,
56.Va hrFSUnknown .
57.It Va hrFSBootable
58It is questionable what bootable means here.
59Does it mean that the BIOS is available to start a boot on that file system
60or does it mean that there is something bootable?
61In either case this information is not available so this variable returns True
62for the root file system (which is not necessarily correct) and False for
63all others.
64.It Va hrFSLastFullBackupDate , hrFSLastPartialBackupDate
65This is not available and always returns an empty string.
66Theoretically, this could be retrieved from
67.Pa /etc/dumpdates ,
68which would
69hardly be correct given the different ways of doing backups.
70.It Va hrDiskStorageTable
71Floppy devices are currently not reported.
72Also the names of the disks are hard-coded in the module.
73.El
74.Sh FILES
75.Bl -tag -width indent
76.It Pa /usr/share/snmp/defs/hostres_tree.def
