Can I have the list of default metrics in Ganglia?
Example: CPU and memory are two of the default metrics collected by Ganglia. Is there a complete list of all the default metrics supported by Ganglia?
I could not get any documentation on the same.

Ganglia provides the following group of default system metrics stored in rrd files per cluster directories:

  1. CPU statistics - Report processors related statistics. Example: cpu user, cpu nice, cpu system, cpu io wait etc.

  2. Disk statistics - Report mount points information. Example: mount points disk size, disk size available etc.

  3. Memory statistics - Reports a large amount of valuable information about the Linux system’s memory. Read about linux meminfo here

  4. Network statistics - Reports network information and data is available in the /proc/net/ directory. Read about linux /proc/net directory

  5. NFS statistics - Reports nfs server and client statistics.

  6. Network interface traffic - Reports interface statistics from /proc/net/dev.

All the above statistics exposes run time system information which exist in /proc virtual file system.Read about proc here

NOTE: Default python metrics files are located under /usr/lib64/ganglia/python_modules directory in python extension.
