Application Container
Mount Directory: /boot, /home, /opt, /dev/shm, /data, and /app, etc.
Replace slash (/) with dot (.) in the mount directory for metrics below
Example: If the original mount directory is /dev/shm, then the mount directory in metrics shall be dev.shm
Physical Disk: sda, sdb, and sdc, etc.

OpenTSDB Storage Metric
The container data are stored in OpenTSDB in the metric format of ‘hostState.metricName’, wherein for metrics whose names are prefixed with os.io.disk.*, the metric format shall be hostState.os.io.disk. Query tags to add ptag. The value shall be the name of specific metric (such as os.io.disk.home.useRate).
Value of instid and pgid in tags shall be container IP, e.g. 10.10.37.44
Tips: Values of all tags are required to be escaped into the valid characters of OpenTSDB. For instance, ':’ should be escaped into ' \u003a '
