Hi,
I am working on support for stats with dynamic-name. This comes handy
in situations where metric-name is dependent upon value of a certain
attribute of the message.
Say, for a central log-aggregation service, its valuable to know what
is inbound message-count distribution across application-clusters that
send logs to it, or for a shared-server, its valuable to know what is
the log-volume generation across users etc.
Im thinking of using functions-like interface to support this. It may
look similar to this:
====================
dyn_stats("user_msg_count")
...
ruleset(...) {
...
dyn_inc("user_msg_count", $.user)
...
}
====================
dyn_stats signature looks like:
dyn_stats(<name_space>, <resettable: default=true>, <max_cardinality:
default=10k>, <recycle_metric_names_after: default=1hr>)
dyn_inc signature looks like:
dyn_inc(<name_space>, <metric_name>)
Reporting would work similar to static-metric via impstats. Mapping:
statsobj_s.name = name_space
statsobj_s.origin = "dyn"
ctr_s.name = "foo" (say $.user had value foo)
Thoughts / suggestions?
