So far, we can monitor Network Devices, like Routers and Switches, by using SNMP OID which we have to find for all resource we want to monitor.
Example: Each interface should have at least two Items incoming and outgoing traffic. So, for a 48-ports switch we have to create 48×2=96 Items. What should we do for a large enterprise with 500 switches? 96×500=48000 Items should be inserted, manually!!!!!!

Templates
A template is a set of entities that can be conveniently applied to multiple hosts. Entities like Items, Triggers, Graphs

You can use the default and pre-installed Templates or you can download some Templates from http://www.zabbix.org/wiki/Zabbix_Templates

 Also you can create new Templates

There are several types of Templates, but we will use Templates which have been prepared for SNMP Using Templates

Example: R1 should use some Templates which uses SNMP. So add Template SNMP Device and then Add {$SNMP_COMMUNITY}=𝐜𝐛𝐭𝟒𝐚𝐥𝐥 in macro tab.
It means use the given string (here cbt4all) as SNMP Community String for all items

You can also edit the Templates if you need more Templates. For example SNMP Device dose not have CPU and Memory Load and Template SNMP Processors have no Item by default

 Install SNMP for Linux Server

• sudo apt-get update
• sudo apt-get install snmpd snmp 
• Edit configuration file: sudo vi /etc/snmp/snmpd.conf and Comment : #agentAddress udp:127.0.0.1:161 and then Uncomment: agentAddress udp:161,udp6:[::1]:161 
• Add Community String: rocommunity cbt4all 
• Restart the SNMP service: sudo service snmpd restart

• https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-an-snmp-daemon-and-client-on-ubuntu-14-04 Install 

Now install SNMP for Windows Server and add it to Zabbix. In this video I use Windows 2012 Server, but you can do it in any edition of the Windows

Now we can monitor Network Devices, like Routers and Switches and Servers like Linux Servers and Windows Servers by using SNMP and Templates, but what if we don’t want to use SNMP? In next video I will show you how you can use the Zabbix Agent in Zabbix to monitor servers easy!
