I am following the clusterlabs documentation that is for RedHat and making
adjustments to Ubuntu.
node01= 10.10.10.100 (zabbix core)
node02= 10.10.10.200 (zabbix core)
VIP= 10.10.10.250
zabbixweb= 10.10.10.2
zabbixbd= 10.10.10.1
I am having problem in zabbix core connection (node01 and node02) with
zabbixbd is coming duplicate data in the database server because the two
core is sending the same information to the database.
As the cluster is active / active wanted a way to information originated by
them also be unique and not each generate the same information and try to
add to the database because it is generating me the errors below.
2016-10-08 12:40:19 BRT [23651-1] zabbix at zabbix ERROR: duplicate key value
violates unique constraint "events_pkey"
2016-10-08 12:40:19 BRT [23651-2] zabbix at zabbix DETAIL: Key (eventid)=(83)
already exists.
And zabbix Server that runs on the node (01 and 02) is giving me these
errors below.
