Доброго времени суток дорогие друзья.
Столкнулся с проблемой, возможно кто-то из вас, уважаемые друзья, знает как это поправить.
триггер в забиксе посылает ложные предупреждения, что SSH упал, но на самом деле все норм, sshd на месте и прекрасно работает.
[root@hostXX log]# cat /etc/issue
CentOS release 6.3 (Final)
Kernel \r on an \m
[root@hostXX log]# zabbix_agent --version
Zabbix agent v2.0.5 (revision 33558) (12 February 2013)
Compilation time: Feb 13 2013 20:29:50
Вот собственно и ошибка:
[root@hostXX log]# grep Did secure

Кофигурация триггера:
{hostXX.domain.com:net.tcp.service[ssh].last(0)}=0
По сути если триггер отключить то и ошибки в логах не появляются, т.е. проблема скорее всего в самом забиксе, но хотелось бы использовать мониторинг на все 100%.
Может кто сталкивался, подскажите пути решения проблемы?
Спасибо друзья!
