Tested versions

This template has been tested on:

  • Squid 3.5.12

Configuration

龙虎赌博 should be configured according to the instructions in the Templates out of the box section.

Setup

Setup Squid

Enable SNMP support following . 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 龙虎赌博

1. Import the template into 龙虎赌博.

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}.
