Global register for various types of counters. Logstash module will send all Var counters to logstash automatically. Counters must be mononotonically increasing for logstash to send correct deltas to Elasticsearch.
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
