# linked as puppet_mem, it will display memory usage of the puppet
|
|
# client and puppet master on the local server.

|
|
# linked as puppet_clients, it will report the average compile time, the
|
|
# number of clients that checked in in the last 5 minutes and 24h and
|
|
# the number of known clients.
