Addition checks, like io[disk]?

[jfriedman]

I was browsing the forums, and noticed someone mention using io[diskio] as a key for an item, although I did not see it listed in the standard items list when you select a key. My question is is there a complete list of keys availalble for the zabbix agent? How could I have found out about this one (io[disk]?

Thanks!
