Re: SNMP Scanning methodby AcidHawk (Vicar) |

I haven't worked with nearly as many servers as you are talking about with perl and snmp, although I have queried 100-120 servers over the WAN. In my experience due to the fact that udp is not guaranteed delivery, querying SNMP over the WAN is NOT advisable. Often these packets get dropped for packets with higher priority (particularly on a WAN link that is heavily burdened.) What I had to do was create staging servers, if you will, that do the snmp queries over the lan and store the responses into a repository of some sort. I use XML. I then use a TCP connection over the WAN links to ship the XML data to my central server, where I process the results from teh snmp queries.
Obviously the Staging Server can just be a Win32 Service or daemon of some type running on an existing piece of hardware. HTH. -----Of all the things I've lost in my life, its my mind I miss the most.
