10 Telnet checks

2.6.8 Overview

Telnet checks are performed as agent-less monitoring. Zabbix agent is not needed for Telnet checks.

2.6.9 Configurable fields

Actual command(s) to be executed must be placed in the Executed script field in the item configuration.
Multiple commands can be executed one after another by placing them on a new line. In this case returned value also will be formated as multi lined.

Supported characters that the shell prompt can end with:

  • $
  • #
  • >
  • %
A telnet prompt line which ended with one of these characters will be removed from the returned value, but only for the first command in the commands list, i.e. only at a start of the telnet session.
