Agent confusion.

Greetings,

 

I'm writing an SNMP agent for some MySQL statistics. After reading the
tutorials and looking at the list archives, I'm still a little confused
on a couple of points.  I'm hoping some of you can help clear this up
for me.

 

I figured out how to write the MIB file and I'm able to run mib2c
against it and get frame code. Once I complete the code, how do I make
snmpd aware of the agent? Does net-snmp need to be recompiled on Linux
to include the new SNMP agent?  Is there any way to dynamically load new
agents in net-snmp?

 

My second point of confusion comes the actual implementation of the code
generated by mib2c.  So far, I have only two objects defined in my MIB
starting at .1.3.6.1.2.1.720 :

 

[root@ccbux2-dev mysqlstat]# snmptranslate -m +MYSQL-DB-MIB -On -IR
mysqlKeyReadRequests

.1.3.6.1.2.1.720.1

[root@ccbux2-dev mysqlstat]# snmptranslate -m +MYSQL-DB-MIB -On -IR
mysql

.1.3.6.1.2.1.720

 

(Yes, I'm using OIDs generated 'at random', that will be changed when I
get a better picture of what I need to accomplish.)

 

 

In the c source file generated by mib2c there is one function
init_mysql(void){..}.  Does that one function's implementation need to
populate mysqlKeyReadRequests (and any other sub-OIDS), or should there
be a separate function to initialize mysqlKeyReadRequests (i.e. I messed
up the MIB file)?

 

 

Any advice would be appreciated.
