Wrong free swap space from centos server

[syco]

Hi,
One of the servers I monitor is reporting the wrong swap size, both server and agent are version 4.2
The client server is a container hosted on LXC.

Attached a screenshot with the values from zabbix interface, I get the same values using zabbix_get and system.swap.size[,pfree]


and this is what I get from the client server command line:

$ free -h
              total        used        free      shared  buff/cache   available
Mem:           4.0G        1.4G        2.3G         96M        320M        2.6G
Swap:          8.0G        168M        7.8G

As you can see the total swap space is correct, but the free swap space and the total memory are not.

Does someone know what could cause it?
Thanks

You are probably looking on wrong host or collecting data from wrong host.

Hi all
I'm having similar problems with windows environments.
The amount of swap used is not the same as you can see in permon.msc.
Both server and client are 4.4.8
Here some pics

Windows says

but Zabbix says


Any ideas?
