> ./openbsd_snmp3.py -h
usage: openbsd_snmp3.py [-h] [--version] -H HOST -l SECLEVEL -u SECNAME
[-a AUTHPROTOCOL] [-A AUTHPASSWORD] [-x PRIVPROTOCOL]
[-X PRIVPASSWORD] -O OPTION [-w WARNING] [-c CRITICAL]

optional arguments:
-h, --help show this help message and exit
--version show program's version number and exit
-H HOST IP addess or hostname of the target host
-l SECLEVEL Set the securityLevel used for SNMPv3 messages
(noAuthNoPriv|authNoPriv|authPriv).
-u SECNAME Set the securityName used for authenticated SNMPv3
messages.
-a AUTHPROTOCOL Set the authentication protocol (MD5|SHA) used for
authenticated SNMPv3 messages.
-A AUTHPASSWORD Set the authentication pass phrase used for authenticated
SNMPv3 messages.
-x PRIVPROTOCOL Set the privacy protocol (DES|AES) used for encrypted
SNMPv3 messages.
-X PRIVPASSWORD Set the privacy pass phrase used for encrypted SNMPv3
messages.
-O OPTION Check target. This can be "cpu", "mem", "swap", "fs" or
"proc" - number of running processes. Use "os" to see
operation system information, "proc" to see table of

-c CRITICAL CRITICAL threshold
