RE: help with hrStorage query

Sorry, I forgot to mention what I think are the incorrect numbers:

 

hrStorageSize.101 = INTEGER: 2097151

hrStorageUsed.101 = INTEGER: 2097151

 

I'm trying to probe and calculate the amount of memory used.

Subject: help with hrStorage query

 

Hello,

 

I'm running into a problem with net-snmp's output of Memory (Ram).  The box
has 4 Megabytes of ram but net-snmp reports something differently.  What I
think I'm seeing is that net snmp is reporting both the total size and used
incorrectly.  I'm trying to get an intermapper probe to work and it's
calculating the memory used using this formula:

 

UsedKB = (hrStorageUsed / 1024) * hrStorageAllocationUnits

 

Dartware is claiming there's a bug in Net-Snamp and it is reporting the
vaule incorrectly because of a division bug for values higher than 2GB ram.

 

Need help, Mahalo Booker.  Below, is the information I gathered.

 

 

I'm running:

net-snmp-5.0.9-2.30E.12

Red Hat Enterprise Linux ES release 3 (Taroon Update 4) (2.4.21-27.ELsmp #1)

Dell Poweredge 1850

 

>From top I have this info of Ram:

Mem:  4095400k av, 4070896k used,   24504k free,       0k shrd,  208632k
buff

                   2257112k actv, 1151872k in_d,   90048k in_c
