      Description

      :~# zabbix_server -V
      Zabbix server v2.2.3 (revision 44105) (7 April 2014)
      Compilation time: May 12 2014 11:40:37

      when using simple tcp checks (which runs from zabbix server) with Timeout for processing items set to 3 (which is default), we can not check if remote service is running (e.g. ssh). This is because when service is down (no process listening on specific tcp port) simple tcp check processing time is above the Timeout configured in Zabbix configuration.

      Running this command from cli:

      ~# zabbix_agentd -t net.tcp.service[tcp,<someip>,<sometcpport>]
      Alarm clock

      Is there any possibility to fix this issue without changing Timeout configuration parameter? Of course, we can even create our own, custom item based on netcat.
