Some Agent plugins generate metrics that may not be desirable on some
installations where resources are severely limited. This change adds
the ability to limit potentially non-essential metrics from some
plugins using the following boolean parameters:
* system: cpu_idle_only (reduces total CPU metrics by 3)
* system: net_bytes_only (reduces network metrics by 6 per device)
* libvirt: ping_only (reduces per-VM metrics by 20+)
These changes are described in more detail in the documentation
accompanying this patch.
monasca-setup now has the ability to configure these parameters
from the command line. For example, to limit all non-essential
system metrics:
monasca-setup -d system -a 'cpu_idle_only=true
net_bytes_only=true
send_io_stats=false'
To limit libvirt per-VM metrics to host_alive_status only:
monasca-setup -d libvirt -a 'ping_only=true' --overwrite
