[SNMP4J] About snmp4j agent

[Frank Fock]

Hi Jacky,

The ManagedObject implementations MOScalar and DefaultMOTable of 
SNMP4J-Agent already provide an in-memory
"database" for MIB data. That data can also be persistently saved to a 
file using the a ready-to-use mechanism.

There several approaches to instrument a SNMP4J-Agent. I always 
recommend reading the
SNMP4J-Agent-Instrumentation-Guide PDF for the details.
If you finally decide to use an external storage (DB or API of something 
else), then you might want
to use the BufferMOTableModel implementations of SNMP4J-AgentX for 
MOTable to optimize
the data access for large tables.

You should in any case define a 1:1 mapping from the table's row index 
to a device and vice versa.
Then its easy to retrieve or update data for each device.

Best regards,
Frank

> I want create a snmp Agent,the agent can manage some devices, I have the MIB for the agent, the mib contain some table and several scalar node, each row for table is represent a device and the column represent the attribute of the device. The several scalar node is represent the agent attribute. I want use the snmp4j agent  implement the Agent. Should I use database to store the temp data for each device? I don't know how to relate the device.You can give me some advice,
