[Percival-users] Problem with Linux memory

[<ea...@ip...>]

Srs,

I have one question.

My monitored Machine, IBM Netvista , Linux Red Hat 9.0 with Net-SNMP.
+-300Mb RAM

The output of top command:


47 processes: 45 sleeping, 2 running, 0 zombie, 0 stopped
CPU states:   0.2% user   0.0% system   0.0% nice   0.0% iowait  99.8% =
idle
Mem:   318832k av,  282968k used,   35864k free,       0k shrd,   61956=
k
buff
                    193212k actv,     564k in_d,    5080k in_c
Swap:  650624k av,    6660k used,  643964k free                  162500=
k
cached


My  percival show this:

The used memory is not correct.


In my /usr/local/percival/lib/Devices/Computers/Linux.pm I see tha OIDs=

used for colect this are:

OID  linuxUsedMemory            1.3.6.1.4.1.2021.4.6.0
OID  linuxFreeMemory             1.3.6.1.4.1.2021.4.5.0

When I try this with snmpwalk the output is:
to 1.3.6.1.4.1.2021.4.5.0: memTotalReal.0 =3D INTEGER: 318832=19
to  1.3.6.1.4.1.2021.4.6.0: memAvailReal.0 =3D INTEGER: 35660

What is wrong?

Txn.
