Dear LXD colleagues,
What is a recommended way of tracking per-container resource usage?
I am hosting a bunch of servers as LXC containers on a single host, and am noticing that over the course of a few days of starting the containers, CPU usage is growing until it hits a ceiling of around 95%.
With the classic Linux system tools like top, htop, etc, I can see that /sbin/init processes, the root process of every container, consume CPU, but cannot tell which containers or which tasks within these containers are the source, and therefore am struggling to decide where to invest into optimizations.
Can anybody here recommend any monitoring tools supporting cgroups, or ways to query LXD?
