Re: CPU consumption

Hi Dave,

Thank you so much for your help. I started reading 5.X version from the time 
you mentioned it yesterday.
>From whatI understand I need to generate a C file and an H file for each 
node that I have in my mib. Can I not generate it for the whole MIB? I have 
about 50 MIBs with a couple of hundred nodes in each and I want to migrate 
to 5.X but it's gonna take forever unless I am missing something.
In addition, what are the configuration files that I should when using 
mib2c. I have for example the following mib:

JINNY-JPM-MIB DEFINITIONS ::= BEGIN

IMPORTS
    enterprises, Counter, Gauge
        FROM RFC1155-SMI
    OBJECT-TYPE
        FROM RFC-1212
    jinny, generic, jpm
        FROM JINNY-MIB;

-- JPM Application Interfaces Counters

profact-total      OBJECT-TYPE
SYNTAX             Counter
ACCESS             read-only
STATUS             mandatory
DESCRIPTION        "Total number of profiles activations"
::= { jpm 1 }

profact-ok         OBJECT-TYPE
SYNTAX             Counter
ACCESS             read-only
STATUS             mandatory
DESCRIPTION        "Number of successfull profiles activations"
::= { jpm 2}


methodTable        OBJECT-TYPE
SYNTAX             SEQUENCE OF METHODEntry
ACCESS             read-only
STATUS             mandatory
DESCRIPTION        ""
::= { jpm 3 }


methodEntry        OBJECT-TYPE
SYNTAX             METHODEntry
ACCESS             read-only
STATUS             mandatory
DESCRIPTION        ""
INDEX             { name }
::= { methodTable 1 }

METHODEntry        ::= SEQUENCE {
                        name            OCTET STRING,
                        profact-total   Counter,
                        profact-ok      Counter}

name            OBJECT-TYPE
SYNTAX          OCTET STRING (SIZE(0..255))
ACCESS          read-only
STATUS          mandatory
DESCRIPTION     "Interface used in the activation"
::= { methodEntry 1 }


profact-total      OBJECT-TYPE
SYNTAX             Counter
ACCESS             read-only
STATUS             mandatory
DESCRIPTION        "Total number of profiles activations in the interface"
::= { methodEntry 2 }

profact-ok         OBJECT-TYPE
SYNTAX             Counter
ACCESS             read-only
STATUS             mandatory
DESCRIPTION        "Number of successfull profiles activations in the 
interface"
::= { methodEntry 3 }

END

woud i have to use mib2c for each node? and what configuration file should i 
use? I need to search for these entries in a table that is loaded in the 
subagent and form what I understand, I need to use
the command:
mib2c -c mib2c.scalar.conf MIBNODE
for my simple nodes and the command that you suggested for my table.
Should I be doing
mib2c -c mib2c.scalar.conf  profact-total
mib2c -c mib2c.scalar.conf  profact-ok
mib2c  -S cache=1 -c mib2c.table_data.conf   methodTable
?
I am sure I am missing something.

Regards,
Marwan
