　　The Host tab contains general host attributes:

ParameterDescriptionHost nameEnter a unique host name. Alphanumerics, spaces, dots, dashes and underscores are allowed.　　Note: With Zabbix agent running on the host you are configuring, the agent configuration file parameter Hostname must have the same value as the host name entered here. The name in the parameter is needed in the processing of active checks.
Visible nameIf you set this name, it will be the one visible in lists, maps, etc. This attribute has UTF-8 support.GroupsSelect host groups the host belongs to. A host must belong to at least one host group.New host groupA new group can be created and linked to the host. Ignored, if empty.InterfacesSeveral host interface types are supported for a host: Agent, SNMP, JMX and IPMI.　　To add a new interface, click on Add in the Interfaces block and enter IP/DNS, Connect to and Port info.
　　Note: Interfaces that are used in any items cannot be removed and link Remove is greyed out for them.
　　Use bulk requests option for SNMP interfaces allows to enable/disable bulk processing of SNMP requests per interface.
IP addressHost IP address (optional).DNS nameHost DNS name (optional).Connect toClicking the respective button will tell Zabbix server what to use to retrieve data from agents:　　IP - Connect to the host IP address (recommended)
　　DNS - Connect to the host DNS name
PortTCP/UDP port number. Default values are: 10050 for Zabbix agent, 161 for SNMP agent, 12345 for JMX and 623 for IPMI.DefaultCheck the radio button to set the default interface.DescriptionEnter the host description.Monitored by proxyThe host can be monitored either by Zabbix server or one of Zabbix proxies:　　(no proxy) - host is monitored by Zabbix server
　　Proxy name - host is monitored by Zabbix proxy “Proxy name”
EnabledMark the checkbox to make the host active, ready to be monitored. If unchecked, the host is not active, thus not monitored.　　The Templates tab allows you to link templates to the host. All entities (items, triggers, graphs and applications) will be inherited from the template.
　　To link a new template, start typing in the Link new templates field until a list of matching templates appear. Scroll down to select. When all templates to be linked are selected, click on Add.
　　To unlink a template, use one of the two options in the Linked templates block:

• Unlink - unlink the template, but preserve its items, triggers and graphs
  
• Unlink and clear - unlink the template and remove all its items, triggers and graphs
  

　　Listed template names are clickable links leading to the template configuration form.
　　See also known issues about template linkage.
　　The IPMI tab contains IPMI management attributes.
ParameterDescriptionAuthentication algorithmSelect the authentication algorithm.Privilege levelSelect the privilege level.UsernameUser name for authentication.PasswordPassword for authentication.　　The Macros tab allows you to define host-level user macros. You may also view here template-level and global macros if you select the Inherited and host macros option. That is where all defined user macros for the host are displayed with the value they resolve to as well as their origin.

　　For convenience, links to respective templates and global macro configuration are provided. It is also possible to edit a template/global macro on the host level, effectively creating a copy of the macro on the host.
　　The Host inventory tab allows you to manually enter inventory information for the host. You can also select to enable Automatic inventory population, or disable inventory population for this host.
　　The Encryption tab allows you to require encrypted connections with the host.
ParameterDescriptionConnections to hostHow Zabbix server or proxy connects to Zabbix agent on a host: no encryption (default), using PSK (pre-shared key) or certificate.Connections from hostSelect what type of connections are allowed from the host (i.e. from Zabbix agent and Zabbix sender). Several connection types can be selected at the same time (useful for testing and switching to other connection type). Default is “No encryption”.IssuerAllowed issuer of certificate. Certificate is first validated with CA (certificate authority). If it is valid, signed by the CA, then the Issuer field can be used to further restrict allowed CA. This field is intended to be used if your Zabbix installation uses certificates from multiple CAs. If this field is empty then any CA is accepted.SubjectAllowed subject of certificate. Certificate is first validated with CA. If it is valid, signed by the CA, then the Subject field can be used to allow only one value of Subject string. If this field is empty then any valid certificate signed by the configured CA is accepted.PSK>Pre-shared key>PSKPre-shared key (hex-string). Maximum length: 512 hex-digits (256-byte PSK) if Zabbix uses GnuTLS or OpenSSL library, 64 hex-digits (32-byte PSK) if Zabbix uses mbed TLS (PolarSSL) library.
