Trap to command rather than remote snmptrapd

I suspect I know the answer to this, but is it possible to get snmpd to run a command when it issues a trap rather than sending out a trap packet? I want to keep an eye on disk space and when it gets to high remove some log files. I wondered if it is possible for snmpd to watch the disk space, and

snmpNotifyFilterTable as per net-snmp 5.4.2.1

Hi, I am using net snmp version 5.4.2.1 As I found that the code is available for snmpNotifyFilterTable but when do the snmpwalk or snmpget then I following error is displaying "SNMP-NOTIFICATION-MIB::snmpNotifyFilterTable = No Such Object available on this agent at this OID" Does that mean

Re: How do you generate a USM localized key?

I tried that and it worked, but it's very awkward to automate - the only way I could find to generate the usmUser record from a createUser record was to run snmpd, but since I use snmpd to monitor all my machines, I've already got an snmpd running on the machine and the two snmpds interfere with ea

Re: Why do I have to start snmpd twice to get USM to work?

As far as I'm aware there is no oldEngineID because the persistent snmpd.conf doesn't exist the first time I run snmpd. The engine IDs I specify on the createUser entries are fairly arbitrary at the moment, but they are different from the EngineID of the snmpd - my understanding is that they're sup
