Is there any alternative to etsy's [statsd](https://github.com/etsy/statsd/ "statsd")? Maybe even a complete dashboard-like solution? My research only found proprietary SaaS solutions. 

For those who do not know: statsd is a deamon which collects app and system metrics via UDP and sends them to Graphite to generate more or less beautiful plots. There is an API for all important languages available. 

I need:

* must run on my servers without a third party collecting the data
* should be able to collect data both from the system, Java and Perl
* should be lightweight and flexible
* FOSS
* may require additional programming, may be only a framework
