==Discovery rule==
 
 
 
You can create a new Discovery rule using the "''create discovery rule''" button. Create a '''Local network''' rule:
 
 
 
[[File:Zabbix discovery rule.png|1024px|caption|Zabbix discovery rule]]
 
 
 
→ Configuration >> Discovery
 
 
 
 
 
Then you should have the following settings:
 
 
 
[[File:Zabbix discovery rule 02.png|none|Zabbix discovery rule 02]]
 
 
 
 
 
IP range: ''your network''
 
 
 
 
 
Checks:
 
* ICMP ping
 
* SNMP v2
 
* SSH
 
* Zabbix agent
 
 
 
 
 
Uniqueness: ''Zabbix agent''
 
 
 
 
 
==Discovery default group==
 
 
 
You can set a '''configuration property''' for the default group of discovered hosts in:
 
 
 
[[File:Zabbix discovery default group.png|1024px|caption|Zabbix discovery default group]]
 
 
 
→ Administration >> General >> Other
 
 
 
 
 
 
 
==Discovery default template==
 
 
 
You can set a ''' discovery action''' to register all Zabbix discovered hosts in a specific template.
 
 
 
[[File:Zabbix discovery default template.png|1024px|caption|Zabbix discovery default template]]
 
 
 
→ Configuration >> Actions >> Discovery
 
 
 
 
 
Then you can either create a new one or edit an existing one.

This explains how to manage hosts.

Hosts overview

Hosts overview

Add host

You have to had a host (= machine with a zabbix agent) on the server side in order to monitor it.


1. Go to the Configuration > Hosts > "Create host"

Zabbix add host


2. Now fill the following details of remote host

Zabbix add host - step 02
  • Hostname: Hostname of Remote system
  • Visible name: Name to be display in zabbix
  • Group: Select the desired group for you host
    • You should use Linux at least
    • You can create your own groups and classification as well
  • Agent interface: Fill the info of Zabbix agent running on host
    • Select the IP option instead of DNS. That will avoid some conflicts between FQDN and simple name.
  • Status: Select initial status


IMPORTANT !!

The name of the hostname must match the real hostname - as return by the `hostname` command !!


3. Set some monitoring templates to apply

Click on the "Templates" tab

Zabbix add host - step 03

To get the list of templates, just type template in the search area.

Don't forget to click the "ADD" button!

  • My custom vehco-smartcards includes the Zabbix agent template
  • The Linux OS includes the Zabbix agent template. :)


4. Automatic host inventory

  • Click on the "host inventory" tab
  • Enable the Automatic option.


5. Click "save" at the bottom of the page.
