RE: 5.1 snmpd hrmib problem

You're confusing two different indexes.

Subject: 5.1 snmpd hrmib problem


In theory, according to the MIB, hrFSStorageIndex is "The index of the 
hrStorageEntry that represents information about this file system.  If 
there is no such information available, then this value shall be zero."

In practice, with a 5.1 snmpd running on Solaris 8, I'm seeing this...

HOST-RESOURCES-MIB::hrFSMountPoint.1 = STRING: "/"
HOST-RESOURCES-MIB::hrFSMountPoint.2 = STRING: "/proc"
HOST-RESOURCES-MIB::hrFSMountPoint.3 = STRING: "/etc/mnttab"
HOST-RESOURCES-MIB::hrFSMountPoint.4 = STRING: "/var"
HOST-RESOURCES-MIB::hrFSMountPoint.5 = STRING: "/var/run"
...

Look at RFC-2790 http://www.faqs.org/rfcs/rfc2790.html


   hrSystem        OBJECT IDENTIFIER ::= { host 1 }
   hrStorage       OBJECT IDENTIFIER ::= { host 2 }
   hrDevice        OBJECT IDENTIFIER ::= { host 3 }
   hrSWRun         OBJECT IDENTIFIER ::= { host 4 }
   hrSWRunPerf     OBJECT IDENTIFIER ::= { host 5 }
   hrSWInstalled   OBJECT IDENTIFIER ::= { host 6 }
   hrMIBAdminInfo  OBJECT IDENTIFIER ::= { host 7 }

HOST-RESOURCES-MIB::hrStorageDescr.2 = STRING: Real Memory
HOST-RESOURCES-MIB::hrStorageDescr.3 = STRING: Swap Space
HOST-RESOURCES-MIB::hrStorageDescr.4 = STRING: /
HOST-RESOURCES-MIB::hrStorageDescr.5 = STRING: /proc
HOST-RESOURCES-MIB::hrStorageDescr.6 = STRING: /etc/mnttab
HOST-RESOURCES-MIB::hrStorageDescr.7 = STRING: /var
HOST-RESOURCES-MIB::hrStorageDescr.8 = STRING: /var/run

That's off hrStorage

It uses hrStorage index


   hrStorageIndex OBJECT-TYPE
       SYNTAX     Integer32 (1..2147483647)
       MAX-ACCESS read-only
       STATUS     current
       DESCRIPTION
           "A unique value for each logical storage area
           contained by the host."
       ::= { hrStorageEntry 1 }

>HOST-RESOURCES-MIB::hrFSStorageIndex.1 = INTEGER: 1
>HOST-RESOURCES-MIB::hrFSStorageIndex.2 = INTEGER: 2
>HOST-RESOURCES-MIB::hrFSStorageIndex.3 = INTEGER: 3
>HOST-RESOURCES-MIB::hrFSStorageIndex.4 = INTEGER: 4
>HOST-RESOURCES-MIB::hrFSStorageIndex.5 = INTEGER: 5

That's off hrDevice, the devices used to implement hrStorage.

It uses hrDeviceIndex


   hrDeviceIndex OBJECT-TYPE
       SYNTAX     Integer32 (1..2147483647)
       MAX-ACCESS read-only
       STATUS     current
       DESCRIPTION
           "A unique value for each device contained by the host.
           The value for each device must remain constant at
           least from one re-initialization of the agent to the
           next re-initialization."
       ::= { hrDeviceEntry 1 }

They would be the same only by coincidence.
