Erlang SNMP and os_mon questions

[Mickael Remond]

Hello,

I have discovered a whole new part of Erlang/OTP I never used before:
SNMP support.

I have started writing a small tutorial to get started.

However I have failed to guess how to use os_mon_snmp. I manage to get
the watermarks figure but I fail to get the real figure.
I can also get Erlang VM information such as erlNodeName, ...

Here is the init sequence I am using:

    application:start(sasl),
    application:start(mnesia),
    application:start(os_mon),
    application:start(snmp),
    otp_mib:load(snmp_master_agent),
    os_mon_mib:init(snmp_master_agent).

And here is the agent debug message log when I try to get the
LoadSystemTotalMemory.

=ERROR REPORT==== 18-Dec-2003::09:57:20 ===

I probably forgot something, but I cannot find anything more in the
documentation. Does someone know here how to make os_mon snmp run
properly ?

Thank you in advance for your help.
