Memory used on Linux 2.6?

[jsosic]

Hi.

I would like to create a graph of memory usage that is similar to HTOP's progress bar, and that's pretty much stacked graph with 3 items:
- Memory total
- Buffers
- Memory used

Now, problem is I don't know how to get memory used from zabbix agent. Is it possible to get it from agent without using external command like free?

1.8 doesn't support used on linux. You need to use a calculated item to generate it, total - free.

2.0 does support used.

Personally I created these extra userparameters years ago, calculated is another way - or waiting for 2.0 indeed

# Extra mem stats
UserParameter=vm.memory.inuse,free -ok | grep ^Mem: | awk '{ print $ 2 - $ 4 - $ 6 - $ 7 }'
UserParameter=vm.memory.diskcache,free -ok | grep ^Mem: | awk '{ print $ 6 + $ 7 }'
