I have an LXC container that has 4GB of swap, most of which is free:
# swapon -s Filename Type Size Used Priority none virtual 4096000 97004 0
However, Zabbix (2.2.5, zabbix-agentd 2.2.7) reports total swap space (and hence free swap space) as zero, and thus reports a problem.
How can I configure Zabbix to recognize the available swap space? Alternatively: is there a newer version of zabbix-agent that does have this problem?
