Overview
This template is designed for network availability monitoring by Zabbix via ping and doesn't require any external scripts.
Requirements
- Zabbix version: 6.0 and higher.
Define user parameters.
Tested versions
This template has been tested on:
Macros used
| Name | Description | Default |
|---|---|---|
| {$ADDRESS1} | address to check availability | 1.1.1.1 |
| {$ADDRESS2} | address to check availability | 8.8.8.8 |
| {$ADDRESS3} | address to check availability | 9.9.9.9 |
Items
| Name | Description | Type | Key and additional info |
|---|---|---|---|
| Network address 1 available | Availability of address 1 by ping | Zabbix agent | 'network.address1[{$ADDRESS1}]' |
| Network address 2 available | Availability of address 2 by ping | Zabbix agent | 'network.address2[{$ADDRESS2}]' |
| Network address 3 available | Availability of address 3 by ping | Zabbix agent | 'network.address3[{$ADDRESS3}]' |
| Network default gateway | Network default gateway | Zabbix agent | 'network.gateway' |
Triggers
| Name | Description | Expression | Severity | Dependencies and additional info |
|---|---|---|---|---|
| Network via {ITEM.VALUE4} not available | last(/Network availability by Zabbix agent/network.address1[{$ADDRESS1}],#1)=0 and last(/Network availability by Zabbix agent/network.address2[{$ADDRESS2}],#1)=0 and last(/Network availability by Zabbix agent/network.address3[{$ADDRESS3}],#1)=0 and length(last(/Network availability by Zabbix agent/network.gateway))>0)<7 | High | Manual close: No | |
| Default gateway has changed (new gateway: {ITEM.VALUE}) | last(/Network availability by Zabbix agent/network.gateway,#1)<>last(/Network availability by Zabbix agent/network.gateway,#2) and length(last(/Network availability by Zabbix agent/network.gateway))>0 | Average | Manual close: Yes |
