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: 7.0 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}.
