Global register for various types of counters
class typ : string -> ?attr:attributes -> string -> object ... endnew typ type ?attr key registers new type of counters with designated attributes and key name
val cc :
('a -> string) ->
string ->
?attr:attributes ->
string ->
'a Cache.Count.tcc pp type ?attr key new set of counters with designated type, attributes and key name
Logstash events will have attributes as follows : * all of attr key value pairs (if given) * class=type * key=X where X is value inserted into CC
Guidelines for picking names : keep number of different key names low (makes ES happy), uniqueness of events is primarily provided by class.
Bad example : let pages = new Var.cc "tool.pages" "pages" let index = new Var.cc "tool.index" "index" let count = new Var.cc "tool.count" "count"
Better : let pages = new Var.cc "tool.pages" "kind" let pages = new Var.cc "tool.index" "kind" let pages = new Var.cc "tool.count" "kind"
val cc_ms :
('a -> string) ->
string ->
?attr:attributes ->
string ->
'a Cache.Count.tcc pp type ?attr key new set of counters with designated type, attributes and key name, treated as milliseconds
val iter : (attributes -> t -> unit) -> unitcallback takes attributes and value
