Hi,

You can take a look at the nginx-lua module (on the logby branch) :
https://github.com/chaoslawful/lua-nginx-module/tree/logby

There is an example in the README :
https://github.com/chaoslawful/lua-nginx-module/blob/logby/README
Look for log_by_lua, and log_by_lua_file.

You can use it to aggregate values, and use another location to report
aggregated data (using content_by_lua) and feed it in your own system.

We use OpenTSDB (http://opentsdb.net/) to keep aggregating data in time series.

Hope that helps,

Matthieu.
