1 Zabbix definitions

Overview
In this section you can learn the meaning of some terms commonly used in Zabbix.

Definitions
host

• a networked device that you want to monitor, with IP/DNS
  .
  host group
• a logical grouping of hosts; it may contain hosts and templates. Hosts and templates within a host group are not in any way linked to each other. Host groups are used when assigning access rights to hosts for different user groups.
  item
• a particular piece of data that you want to receive off of a host, a metric of data.
  trigger
• a logical expression that defines a problem threshold and is used to “evaluate” data received in items
  When received data are above the threshold, triggers go from 'Ok' into a 'Problem' state. When received data are below the threshold, triggers stay in/return to an 'Ok' state.
  event
• a single occurrence of something that deserves attention such as a trigger changing state or a discovery/agent auto-registration taking place
  problem
• a trigger that is in “Problem” state
  action
• a predefined means of reacting to an event.
  An action consists of operations (e.g. sending a notification) and conditions (when the operation is carried out)
  escalation
• a custom scenario for executing operations within an action; a sequence of sending notifications/executing remote commands
  media
• a means of delivering notifications; delivery channel
  notification
• a message about some event sent to a user via the chosen media channel
  remote command
• a pre-defined command that is automatically executed on a monitored host upon some condition
  template
• a set of entities (items, triggers, graphs, screens, applications, low-level discovery rules, web scenarios) ready to be applied to one or several hosts
  The job of templates is to speed up the deployment of monitoring tasks on a host; also to make it easier to apply mass changes to monitoring tasks. Templates are linked directly to individual hosts.
  application
• a grouping of items in a logical group
  web scenario
• one or several HTTP requests to check the availability of a web site
  frontend
• the web interface provided with Zabbix
  Zabbix API
• Zabbix API
  allows you to use the JSON RPC protocol to create, update and fetch Zabbix objects (like hosts, items, graphs and others) or perform any other custom tasks
  Zabbix server
• a central process of Zabbix software that performs monitoring, interacts with Zabbix proxies and agents, calculates triggers, sends notifications; a central repository of data
  Zabbix agent
• a process deployed on monitoring targets to actively monitor local resources and applications
  Zabbix proxy
• a process that may collect data on behalf of Zabbix server, taking some processing load off of the server
