Squid by SNMP

Overview

This template is designed for the effortless deployment of Squid monitoring by Zabbix via SNMP and doesn't require any external scripts.

Requirements

Zabbix version: 7.4 and higher.

Tested versions

This template has been tested on:

Squid 3.5.12

Configuration

Zabbix should be configured according to the instructions in the Templates out of the box section.

Setup

Setup Squid

Enable SNMP support following official documentation. Required parameters in squid.conf:

snmp_port <port_number>
acl <zbx_acl_name> snmp_community <community_name>
snmp_access allow <zbx_acl_name> <zabbix_server_ip>

Setup Zabbix

1. Import the template template_app_squid_snmp.yaml into Zabbix.

2. Set values for {$SQUID.SNMP.COMMUNITY}, {$SQUID.SNMP.PORT} and {$SQUID.HTTP.PORT} as configured in squid.conf.

3. Link the imported template to a host with Squid.

4. Add SNMPv2 interface to Squid host. Set Port as {$SQUID.SNMP.PORT} and SNMP community as {$SQUID.SNMP.COMMUNITY}.

Squid SNMP

Overview

For Zabbix version: 5.4 and higher

This template was tested on:

Squid, version 3.5.12

Setup

See Zabbix template operation for basic instructions.

Setup Squid

Enable SNMP support following official documentation. Required parameters in squid.conf:

snmp_port <port_number>
acl <zbx_acl_name> snmp_community <community_name>
snmp_access allow <zbx_acl_name> <zabbix_server_ip>

Setup Zabbix

1. Import the template template_app_squid_snmp.yaml into Zabbix.

2. Set values for {$SQUID.SNMP.COMMUNITY}, {$SQUID.SNMP.PORT} and {$SQUID.HTTP.PORT} as configured in squid.conf.

3. Link the imported template to a host with Squid.

4. Add SNMPv2 interface to Squid host. Set Port as {$SQUID.SNMP.PORT} and SNMP community as {$SQUID.SNMP.COMMUNITY}.

Zabbix configuration

No specific Zabbix configuration is required.
