# Network availability by Zabbix agent
## 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.`](https://git.hmp.today/pavel.muhortov/zabbix/templates/components/network-availability/6.0#define-user-parameters)
## Tested versions
This template has been tested on:
- [Debian GNU/Linux 11](http://ftp.debian.org/debian/dists/bullseye/)
- [Windows 11](https://www.microsoft.com/en-us/windows/windows-11)
### 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|
### Discovery rules
There are no discovery rules in this template.
### Item prototypes for Clients discovery
There are no item prototypes in this template.
### Define user parameters
for Linux:
```bash
tee -a /etc/zabbix/zabbix_agentd.conf > /dev/null <<'EOF'
Timeout=30
UserParameter=network.gateway, ip ro | grep -e default | awk '{print $3}'
UserParameter=network.address1[*], ping -q -w 3 -c 1 $1 > /dev/null && echo 1 || echo 0
UserParameter=network.address2[*], ping -q -w 3 -c 1 $1 > /dev/null && echo 1 || echo 0
UserParameter=network.address3[*], ping -q -w 3 -c 1 $1 > /dev/null && echo 1 || echo 0
EOF
systemctl restart zabbix-agent
```
for Windows:
```batch
powershell.exe
$text = @"
Timeout=30
UserParameter=network.gateway, powershell.exe -Command "Get-NetRoute -DestinationPrefix '0.0.0.0/0' | Select-Object -ExpandProperty 'NextHop'"
UserParameter=network.address1[*], ping -w 3000 -n 1 $1 > NUL && echo 1 || echo 0
UserParameter=network.address2[*], ping -w 3000 -n 1 $1 > NUL && echo 1 || echo 0
UserParameter=network.address3[*], ping -w 3000 -n 1 $1 > NUL && echo 1 || echo 0
"@
$text | Out-File -Append "$env:ProgramFiles\Zabbix Agent\zabbix_agentd.conf" -Encoding "UTF8"
exit
sc stop "Zabbix Agent" && sc start "Zabbix Agent"
```
