In this section you can learn the meaning of some terms commonly used in Zabbix.
- a networked device that you want to monitor, with IP/DNS.
- a logical grouping of hosts. Host groups are used when assigning access rights to hosts for different user groups.
- a particular piece of data that you want to receive off of a host, a metric of data.
- a transformation of received metric value before saving it to the database.
- 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.
- a single occurrence of something that deserves attention such as a trigger changing state or a discovery/agent autoregistration taking place.
- a pre-defined marker for the event. It may be used in event correlation, permission granulation, etc.
- a method of correlating problems to their resolution flexibly and precisely.
For example, you may define that a problem reported by one trigger may be resolved by another trigger, which may even use a different data collection method.
- a trigger that is in "Problem" state.
- problem management options provided by Zabbix, such as adding comment, acknowledging, changing severity or closing manually.
- 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)
- a custom scenario for executing operations within an action; a sequence of sending notifications/executing remote commands.
- a means of delivering notifications; delivery channel.
- a message about some event sent to a user via the chosen media channel.
- a pre-defined command that is automatically executed on a monitored host upon some condition.
- a set of entities (items, triggers, graphs, 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.
- a logical grouping of templates. Template groups are used when assigning access rights to templates for different user groups.
- one or several HTTP requests to check the availability of a web site.
- the web interface provided with Zabbix.
- customizable section of the web interface displaying summaries and visualizations of important information in visual units called widgets.
- visual unit displaying information of a certain kind and source (a summary, a map, a graph, the clock, etc.), used in the dashboard.
- 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.
- a central process of Zabbix software that performs monitoring, interacts with Zabbix proxies and agents, calculates triggers, sends notifications; a central repository of data.
- a process that may collect data on behalf of Zabbix server, taking some processing load off of the server.
- a process deployed on monitoring targets to actively monitor local resources and applications.
- a new generation of Zabbix agent to actively monitor local resources and applications, allowing to use custom plugins for monitoring.
Because Zabbix agent 2 shares much functionality with Zabbix agent, the term "Zabbix agent" in documentation stands for both - Zabbix agent and Zabbix agent 2, if the functional behavior is the same. Zabbix agent 2 is only specifically named where its functionality differs.
- support of encrypted communications between Zabbix components (server, proxy, agent, zabbix_sender and zabbix_get utilities) using Transport Layer Security (TLS) protocol.
- automated discovery of network devices.
- automated discovery of low-level entities on a particular device (e.g. file systems, network interfaces, etc).
- set of definitions for automated discovery of low-level entities on a device.
- a metric with certain parameters as variables, ready for low-level discovery. After low-level discovery the variables are automatically substituted with the real discovered parameters and the metric automatically starts gathering data.
- a trigger with certain parameters as variables, ready for low-level discovery. After low-level discovery the variables are automatically substituted with the real discovered parameters and the trigger automatically starts evaluating data.
Prototypes of some other Zabbix entities are also in use in low-level discovery - graph prototypes, host prototypes, host group prototypes.
- automated process whereby a Zabbix agent itself is registered as a host and started to monitor.
