I would like to know in CF, how to integrate with 3rd party app logging and monitoring like Graphite, Nagios, etc, what is the recommended approach. I found few articles where its mentioned firehose is the better option. Whereas I remember having collector (stats_z1/z2) job pointing to such monitoring server works well. So what steps I need to follow if I have to integrate such application monitoring tool using firehose? Do I need to write Nozzles for my monitoring tool like CloudCredo did for Graphite? https://github.com/CloudCredo/graphite-nozzle http://www.cloudcredo.com/how-to-integrate-graphite-with-cloud-foundry/
So if I have to integrate with Nagios, Wily, Splunk etc I would need nozzle for all of them? If not what changes I need to do in my configuration and in buildpack(not sure)?

I also found NOAA client https://github.com/cloudfoundry/noaa which I think consumes all logs from doppler and show them on console? How this Noaa client is using firehose, is not very clear in the document?

what is your logging and metrics tool? does it have an api?

the loggregator nozzle's are the go-forward approach to tapping into logs
and metrics in the entire cf system and sending them somewhere.
