collectd is a daemon that collects statistics in a round-robin database, for subsequent performance analysis. I'm deploying it as a replacement for munin.
When I deploy collectd nodes in containers, many of the basic plugins are not useful, because (as at 2.6.32) queries like "how much memory is free?" return the dom0's state, rather than the container's. In collectd 4.9 someone solved this for OpenVZ by running collectd on the HN (i.e. dom0) and having it emit statistics for all containers. I think it can be translated to LXC by having it read files in /path/to/cgroup/<container name>/. Has anyone already written an LXC collectd plugin? ------------------------------------------------------------------------------ The ultimate all-in-one performance toolkit: Intel(R) Parallel Studio XE: Pinpoint memory and threading errors before they happen.
