Hi,
I have been working on a config file to allow mib2c to generate the support
code for the embedded perl agent, and Thomas Anders suggested that I submit
this for possible inclusion into net-snmp, which I am now ready to do.
Can you let me know what format I should submit this and to whom.
Summary:
The main purpose of this work is to allow developers to quickly product
agent code using the embedded perl support in net-snmp. Using perl allows
agents to be quickly developed and deployed when compared to traditional C
coding. This is particularly useful when the data required is in external
config files where Perl's data handling comes into its own.
In outline, the mib2perl package consists of a config file for mib2c and a
supporting perl module.
The output is an agent_xxx.pl file that can be executed from the snmpd.conf
file.
It registers using the topmost oid of the mibs(s) given to mib2c.
The code generated consists of:
- A hash data structure containing OID strings as the primary key, and
references to various helpers.
- Skeleton helpers for all the objects in the mibs.
The user of this utility would take the skeleton functions and fill in the
details, the SnmpAgent module taking care of the rest.
Support for tables with multiple indexes is supported, as well as scalars.
Testing:
This has been tested on 3 mibs we have written for our products, 3 tables,
one with two INTEGER indexes, the others with a single INTEGER index.
Known limitations:
The major limitation is that indexes must be simple objects - integers etc,
not OIDs or other objects that require more complex identifiers.
The code is probably sub-optimal in several places, I have not attempted to
fine-tune the generation of the code, nor have I done any explicit
optimisation on the run-time support.
Does not run with strict yet.
