Setup SNMP Trap monitoring for vCenter Server Appliance with Zabbix

Environment

• VCSA 6.0
• Zabbix 3.0
  • on Ubuntu 14.04

Zabbix Server side

• Install snmpd and snmptt

  apt-get install snmpd snmp snmp-mibs-downloader snmptt libnet-snmp-perl
  

• Edit /etc/snmp/snmptrapd.conf

  cat <<EOF >> /etc/snmp/snmptrapd.conf
  authCommunity log,execute,net public
  perl do "/usr/lib/snmptt/snmptthandler-embedded";
  EOF
  

• Edit /etc/default/snmpd

  sed -i 's/TRAPDRUN=no/TRAPDRUN=yes/' /etc/default/snmpd
  sed -i "s/TRAPDOPTS='-Lsd/TRAPDOPTS='-On -Lsd/" /etc/default/snmpd
  

• Start snmpd

  service snmpd start
  

• Edit /etc/snmp/snmptt.ini

  sed -i 's;#date_format = %a %b %e %Y;date_format = %H:%M:%S %Y/%m/%d;' /etc/snmp/snmptt.ini
  sed -i 's/syslog_enable = 1/syslog_enable = 0/' /etc/snmp/snmptt.ini
  sed -i 's/net_snmp_perl_enable = 0/net_snmp_perl_enable = 1/' /etc/snmp/snmptt.ini
  sed -i 's/net_snmp_perl_cache_enable = 0/net_snmp_perl_cache_enable = 1/' /etc/snmp/snmptt.ini
  

• Download MIB file from SNMP MIB module file download (1013445)

• Import MIB files

  unzip 1013445_VMware-mibs-6.0.0-2906283.zip
  mkdir -p /usr/share/mibs/site/
  cp -p vmw/*.mib /usr/share/mibs/site/
  

• Convert MIB files to SNMPTT config

  mkdir -p snmpttconf/vmw
  for i in `ls vmw/*.mib`; do snmpttconvertmib --in=$i --out=snmpttconf/$i.conf; done
  cat snmpttconf/vmw/*.conf > snmptt.vmw.conf
  sed -i 's/FORMAT/FORMAT ZBXTRAP $aA/g' snmptt.vmw.conf
  cp -pb snmptt.vmw.conf /etc/snmp/snmptt.conf
  

• Restart snmptt

  service snmptt restart
  

• Edit /etc/zabbix/zabbix_server.conf

  cat <<EOF >> /etc/zabbix/zabbix_server.conf 
  StartSNMPTrapper=1
  SNMPTrapperFile=/var/log/snmptt/snmptt.log
  EOF
  

• Restart Zabbix Server

  service zabbix-server restart
  

• Create SNMP Trap item. And set the key like snmptrap["Events"].

vCenter side

• Set snmp trap target

  snmp.set --targets {Zabbix Server Address}@162/public
  

• Enable snmp service

  snmp.enable
  

Test

• Send a test trap from VCSA.

  snmp.test
