Re: [pysnmp-users] Throttling asyncore transmit.

[Ilya E. <et...@gm...>]

Hi Peter,

I think the easiest approach would be to make your script sending SNMP queries in chunks. In other words, you can implement the rate limiting yourself.

If you take this simple example [1] and invoke `getCmd` for a subset of your SNMP agents/OIDs from the callback function `cbFun`, that should give you total control on the packet flood you generate. So once you get a response (or time out), the `cbFun` get invoked by pysnmp. Then, besides consuming the response you can send some more SNMP queries.

Keep in mind that you still need the initial `getCmd` to get things running.

p.s. I’d suggest moving to GitHub issues for further communication as SourceForge seems to become less relevant unfortunately
