There is an indication that the value returned by OBSD for SNMP-FRAMEWORK-MIB::snmpEngineTime.0 is incorrect. On my discussion on the Cacti forum, https://forums.cacti.net/viewtopic.php?p=297860&sid=1a77491941fff1bd5572c5334095913b#p297860, it was brought up that "the SNMP-FRAMEWORK-MIB::snmpEngineTime.0 object is designed to track the operational status of an SNMP engine. It specifically measures the time elapsed since the last change in the snmpEngineBoots value." However, OBSD is returning wall clock time. This is causing some confusion with the Cacti poller.

Thanks. > > You can read more details here: > https://forums.cacti.net/viewtopic.php?t=64129 I'm not using cacti, but I'm doing SNMP polling from PHP using LibreNMS (which uses a mixture of functions from PHP's SNMP extension and calls to snmpget/snmpbulkwalk etc) and that's working ok, so FWIW I don't think there's a general problem with PHP/SNMP. spine is a bit problematic on non-linux systems, install docs tell you that it needs to be setuid root (though not in so many words, they just tell you to use chmod u+s) but it only drops privileges if you have linux "libcap" (and then only to the uid who started it; if started by root then it doesn't drop to a lower privileged user). I don't know about you but I wouldn't really want net-snmp + mariadb client + ssl libs + spine code in a process running as root. -- Please keep replies on the mailing list.
