Thanks for your help.
Unfortunately my code doesn't get called on the agent's exit.
But calling the function finalize_myagent_scalar() using the
callback mechanism via
snmp_call_callbacks( SNMP_CALLBACK_LIBRARY, SNMP_CALLBACK_STORE_DATA, NULL)
does work, after having it registered like you suggested.
The agent is a simple subagent generated using mib2c and communicating
with the master agent via agentx. It is sitting at the right place in
the agents/ directory, so the script "/etc/init.d/snmpd start"
successfully starts my subagent with snmpd. Getting and setting
values of my custom MIB works like a charm.
But that's not even my main concern, as storing data using the
default store mechanism doesn't work out like I expected, either:
In my init function, I registered a variable using
netsnmp_ds_register_config( ASN_INTEGER, "myagent", "myvalue",
NETSNMP_DS_APPLICATION_ID, NETSNMP_DS_MYAGENT_MYVALUE)
and expect it to be stored on the agent's exit in the file
/var/net-snmp/myagent.conf in a line like
myvalue=<whatever_int_i_stored>
and being retrieved on the agents start, being readily available to
be read, umm, via
netsnmp_ds_get_int( NETSNMP_DS_APPLICATION_ID, NETSNMP_DS_MYAGENT_MYVALUE)
But it keeps returning a value of 0 on a freshly started agent, instead of
the value I had stored previously using
netsnmp_ds_set_int( NETSNMP_DS_APPLICATION_ID, NETSNMP_DS_MYAGENT_MYVALUE,
myvalue)
the last time before the agent was shut down.
Enlightenment is apprecciated :)
