UDP is actually expected to work better than TCP in lossy networks (or congested networks). TCP is far better at transferring large quantities of data, but when the network fails it’s more likely that UDP will get through. (in fact, I recently did a study testing this and it found that SNMP over UDP succeeded … Read more

Use snmpwalk to see what the machine is reporting, and pick what looks appropriate 🙂 For CPU utilization, the Host Resources MIB provides a SNMP Table at 1.3.6.1.2.1.25.3.3 which lists each CPU and it’s current percent utilization, but these values can be somewhat misleading (100% doesn’t always mean your system is overloaded). www.oidview.com is a … Read more
Windows Server has a built in SNMP trap generator for the Windows Event Log/Viewer, which can send traps on the occurrence of arbitrary events. Trap Form (OID) These traps will conform to the Microsoft private enterprise MIB branch in the following form: 1.3.6.1.4.1.311.1.13.X.n.n.n.n.n.n.n.n.n… Each “n” is a decimal encoding of an ASCII character octet from … Read more
A co-worker just showed me samplicator. This tool looks to be just about a perfect solution what I was looking for. From the tool’s website: This simple program listens for UDP datagrams on a network port, and sends copies of these datagrams on to a set of destinations. Optionally, it can perform sampling, i.e. rather … Read more
Deprecated in this sense does not mean SNMP is no longer available in Server 2012. It’s still right there, installable as a feature. “Deprecated” in this sense is simply a yellow flag to say “hey, we want to get rid of this some time in the indeterminate future.” I highly doubt the decision has been … Read more
Sadly, SNMP is still in common usage. Later versions of the protocol have addressed numerous issues in SNMPv1, but those have almost entirely been directed at fixing the security model. As a result, SNMP traffic is now comparitively bloaty, but they have not addressed what I consider to be the glaring shortcoming in SNMP – … Read more
You may give a try at MIB Browser from iReasoning, the free version is only limited to the number of loaded MIBs (10 at once). Hope this helps.
apt-get install snmp-mibs-downloader The above command downloads various non-free MIBs which the free MIBs (included with distro) require to work. There are still a handful of errors, after installing this non-free package, but the snmpwalk now works.
