Q. Can I configure zabbix so that I do or do not get multiple notifications each time a poll event occurs?
A. Yes, This is configuration is found in the Configuration/Actions section documentation and is defined under Enable Escalations.
Q. I would like to monitor hardware characteristics such as temperature, fans, power etc.. What do I need to do to set this up in Zabbix?
A. Zabbix supports IPMI which is supported by most computer server vendors like HP, Sun and Dell. You will need to set up IPMI management in the server's BIOS generally on the Lights Out Management card and then test it with impitools. IPMI configuration in Zabbix is found under Configuration / Hosts and you will need the IP address of the LOM on your server and authentication/authoriztion information that you set up on your server.
