[rrd-users] Re: maybe a bit off topic (4GB RAM snmp)

[Simon Mullis]

What happens if you try the following:

snmpget -v2 -c public 10.0.0.12 .1.3.6.1.4.1.2021.4.6.0

As far as I understand, SNMPv2c uses 64bit counters.

(Or am I merely confused?)

her is the output:
term$ snmpget -v1 -c public 10.0.0.12 .1.3.6.1.4.1.2021.4.6.0
enterprises.ucdavis.memory.memAvailReal.0 = -1

the same thing with localhost.


same as before... 
this is weird since i also graph a unix harddrive on another machine
with 10 GB and it shows it perfectly. I guess i have to check in some
other places. it doesnt make much sense though....There must be more
people out there monitoring 4GB ram with snmp.


Anyway, thanks for the help.

Just out of interest are you using the "numbered" OID or the names as
you 
outlined above? I believe if you want to use the "memory.memAvailReal.0"

syntax then you have to use the "LoadMIB" directive (I could be wrong).
What 
happens if you try an snmpget?

(Don't laugh, that's 1MB of free memory!!)

I am using MRTG/RRDTool to graph free space on my XP desktop hard drives
(one 
is 40GB and the other is 60GB) and these graph without any hassles.
