In a similar system, the data pulled by the sub-poller is much less than that pulled by the master poller. Why is this happening, and what should I do about it?
slave poller just port,as below
Could be lots of reasons.
You’ve not enabled discovery
You’ve disabled the discovery modules
You’ve restricted what info comes back via snmpv3 if you are using that.
already enable discovery,in web ui for that poller.
seems discovery action should be enabled inside.
I user snmp v2
how to check inside step by step
by the way,in distributed poller,I want to know how to stop/start poller
