Alerting via SNMP TRAP


Install Prerequisites (skip that in case of Virtual Appliance)

  • AIX
    Download Net-SNMP packages and install them.
    Do not use the latest packages for AIX, it does not work, use net-snmp-5.6.2.1-1! It will not work with AIX standard OS cmd /usr/sbin/snmptrap!
    # umask 0022
    # rpm -Uvh net-snmp-5.6.2.1-1 net-snmp-utils-5.6.2.1-1 net-snmp-perl-5.6.2.1-1
    
    Make sure
    • you use PERL=/opt/freeware/bin/perl in etc/stor2rrd.cfg
    • PERL5LIB in etc/stor2rrd.cfg contains /opt/freeware/lib/perl5/vendor_perl/5.8.8/ppc-thread-multi path
  • Linux
    # umask 0022
    # yum install net-snmp
    # yum install net-snmp-utils
    # yum install net-snmp-perl
    
  • Linux Debian/Ubuntu
    % umask 0022
    % apt-get install snmp libsnmp-perl snmp-mibs-downloader
    
    Assure that this line is commented out in /etc/snmp/snmp.conf
    #mibs :
    
    If apt-get does not find snmp-mibs-downloader package then enable contrib and non-free repositories.

Trap testing

You can test trap from cmd like (AIX example):
# export SNMP_PERSISTENT_DIR=/tmp
# /opt/freeware/bin/snmptrap -v 1 -c public 127.0.0.1 1.3.6.1.4.1.40540.1.0.1.0.7 '' 6 7 '' 1.3.6.1.4.1.40540.1.1 s hmcXY 1.3.6.1.4.1.40540.1.2 s serverXY 1.3.6.1.4.1.40540.1.3 s lparXY 1.3.6.1.4.1.40540.1.4 s 'CPU' 1.3.6.1.4.1.40540.1.5 s 9.9
