Hi,
Many thanks for this tool.
Total number of CPU cores on my system is 16, so I expect a max cpu user time of 1600% but I am getting higher values than this.
I am using zabbix 3.2
Kindly help.

Ubuntu 16.04.1 LTS

Just to note, I have seen the following after running "make", yet, the module was created.

On Debian jessie (8.6) performs the commands "./configure --enable-agent" to:

Hi, I'm running LXD 4.7 on Ubuntu 20.04
Since directories hierarchy of LXD stats has been changed from /sys/fs/cgroup/cpuset/lxc to something like
/sys/fs/cgroup/cpuset/lxc.monitor.containername
/sys/fs/cgroup/cpuset/lxc.payload.containername
we are have some errors :)
