FnordMetric: setting user picture/name and unique gauges

gistfile1.rb

# i hope this helps...

# to set the username and picture send these events to fm
# -> you don't need to define any event handlers
# -> the session token (_session) could be your unique session id 
#    or the unique user id (it's hashed)

# set the user name
{ "_type": "_set_name", "name": "Tingle Tangle Bob", "_session": "mysessiontoken" }

# set the user picture
{ "_type": "_set_picture", "url": "http://myhost/123.jpg", "_session": "mysessiontoken" }

# track a pageview
{ "_type": "_pageview", "url": "http://myhost/mypath", "_session": "mysessiontoken" }



# if you want to count action/events unique per session you can 
# set up an event handler like this:

gauge :myaction_uniqe, 
  :tick => 1.day.to_i, 
  :unique => true

event :myaction do
  incr :myaction_uniqe
end

# and send events like this one:
{ "_type": "myaction", "_session": "mysesstiontoken" }

# the gauge will only be incremented once per session token (and tick/interval)
# so this gauge would show "daily unique myactions"



# if you want e.g. the average body size of all users on a given day:

gauge :average_body_size, 
  :tick => 1.day.to_i, 
  :unique => true,
  :average => true

event :user_body_info do
  incr :average_body_size, data[:body_size]
end

# events:
{ "_type": "user_body_info", "body_size": 186, "_session": "userid_1" }
{ "_type": "user_body_info", "body_size": 162, "_session": "userid_2" }
{ "_type": "user_body_info", "body_size": 173, "_session": "userid_3" }
