Hi, I'm running dockerized version of dockbix-agent-xxl. Zabbix can discovery the items, but only items working is the one do not use memory.stat.

Docker info:

How did you start container?

20:20181018:104825.643 Metric source file: /rootfs/sys/fs/cgroup/memory/docker/1f837d5ec19b48ce8743623aa91b214783674d877be37afd8fa79db171ee0a83/memory.stat 20:20181018:104825.643 Looking metric total_swap in memory.stat file 20:20181018:104825.643 Sending back [ZBX_NOTSUPPORTED: Cannot find a line with requested metric in memory.stat file]

Probably you don't have enabled memory metrics, see https://github.com/monitoringartist/zabbix-docker-monitoring:

Note: if you have a problem with memory metrics, be sure that memory cgroup subsystem is enabled - kernel parameter: cgroup_enable=memory
