Get RAM with zabbix agent

[vanessa]

Is there simply a key to get the free RAM in Zabbix via the zabbix agent2 on linux? I'm fidning none. Seems like you have to make your own?

The items and triggers that comes with the standard template force you to include swap and other caches in the calculation of used memory.

Linux host: available memory item (in linux agent template)
Windows host, make template item,calculated item: Total memory - Used memory (in the windows Agent template)

MY mistake. I don't think it does include the SWAP. I assumed that "cache" included swap. Rather, cache and buffers is still the same RAM with special purposes.

swap is all different... It does not have to be present at all
