Registering over 5000 scalars with snmpd from my AgentX takes 2-3 minutes, and
in that time snmpd has a massive CPU load.
Is there any way to speed this up, and without having snmpd consume so much of
the CPU? Even though it is only a few minutes, we are not keen on snmpd taking
that much of th

Anyway: Here is one radical thought. What about using snmpget to trigger a
command? At least when no parameters are sent it would be perfect and simple.

I'm not sure what I did to fix the problem. After fiddling with the code on
several places(many which was non-SNMP specific) the problem got solved.
Running snmpwalk now stops at the last OID in that subtree.

Regular snmpget works perfectly with my SNMP AgentX, but I'm having some

Does the master agent handle it if I register a higher order scalar before a
lower order scalar?
I have checked the snmpd logfile and cannot find any information on why these
few scalars takes longer time to register.

I have aprox 4000 scalars. When I go through my list of scalars it is able to
register them very fast, but for some reason one a handful of scalars it takes
a few seconds.
My ordering of the list of scalars might not be perfect. It is a

Emne: Callback logging
Scouring the web and
Scouring the web and the mailing list archive for information about
implementing a callback logging. I could only find bits and pieces.
If I haven't overlooked it and it is actually there, I think this information
should be available on the Net-SNMP Wiki. A small tutorial on how to implement
device multiple times, since both handler
and callback are executed multiple times.
My technique of putting each request(delegated_cache) in a list did not work so
well. Beside it will not work if I get two requests for the same OID.

I have implemented a delegated response with a 2 seconds delay time.
My handler function handle_snmp and callback function delayed_response gets
called/executed several times for the same requests. Why is that? Is it a
feature or a bug? If its a feature is it how it handles the delay by executi

Is registering an Net-SNMP alarm the only way to delay a response?
I don't need to delay for a given amount of time, but until a signal is

If not, the only possible way I see to get around this is to use an alarm with
a timeout delay. Wait f
