No. net-snmp was installed before. Is there any way to create that file (check_snmp) ?

Never-mind. I re-installed plugins and now I have check_snmp file.

./check_snmp
check_snmp: Could not parse arguments
Usage:
check_snmp -H <ip_address> -o <OID> [-w warn_range] [-c crit_range]
[-C community] [-s string] [-r regex] [-R regexi] [-t timeout] [-e retries]
[-l label] [-u units] [-p port-number] [-d delimiter] [-D output-delimiter]
[-m miblist] [-P snmp version] [-N context] [-L seclevel] [-U secname]
[-a authproto] [-A authpasswd] [-x privproto] [-X privpasswd]
[root@localhost libexec]# ./check_snmp -m ALL
No host specified

What is next? Do you have step-by-step manual for that?

Well, there's http://nagios-plugins.org/doc/man/check_snmp.html. You're going to need a FQDN or ip address. One of the simplest commands would be as follows.
It's a video, not documentation, but https://support.nagios.com/kb/article.p ... ategory=14 might be useful if you are just getting started with snmp.
