Template:FAQ:Agent 33
From Net-SNMP Wiki
These mib modules are not supported on all operating systems, and will not be included on any other system. Currently, they are only supported on Linux, HP-UX (memory only), Solaris, BSDi (vmstat on BSDi4 only), Dynix, FreeBSD, NetBSD and OpenBSD. If you want to help port it to other systems, let us know.
Note that these subtrees only report the current usage when explicitly queried. They do not automatically generate traps when the usage strays outside the configured bounds. See the earlier FAQ entry What traps are sent by the agent? for more information
