Is there any other implementation where i can still use container_load and implement some logic in where if i issue any snmp command it should run the subagent code again.
What my understanding is that the net-snmp master agent is implementing some cache. Whenever i issue some snmp command, the results for the MIB objects are stored in the cache . So the next consecutive results for snmp commands are returned from the cache instead of calling my logic ie calling container_load function.

Your help is appreciated.
Thanks in advance.

There is no way to know when you are issuing a snmptable command, as the agent
simply sees a series of get-next requests.

Take a look at the ifTable implementation in agent/mibgroups/if-table/*. It
uses the cache helper to periodically reload the cache (every 20 seconds or
so). If you have some sort of external trigger you can check (like if some
file has been touched), you can use the cache helper for that too.
