Graphite 'backend'. Twisted-based server accepts graphite source metrics and forward them to blueflood.
Server accepts only pickle protocols metrics (as it's the only protocol used by graphite carbon-relay.)
It does very primitive 'caching': aggregates all metrics and flushes them in regular intervals.

| Switch | Description | default |
|---|---|---|
| -e | Endpoint to listen on for pickle protocol metrics | tcp:2004 |
| -i | Metrics send interval, sec | 30.0 |
| -b | Blueflood address | http://localhost:19000 |
| -t | Tenant ID | tenant |
| -p | Prefix to be prepended to metrics name | metric_prefix |
| --ttl | TimeToLive value for metrics, sec | 86400 |
| -u | Keystone user | |
| -k | Keystone key | |
| --auth-url | Keystone token URL |
In case you need no authentication leave -u/--user command line argument empty (default value).
To send a test metric to the twistd server you started above, you can run the following:
python tests/scripts/sendPickle.py
Modify the script accordingly for your local testing
Configuration is done with command line arguments passed to twistd daemon when running:
twistd -n -l - blueflood-forward --help
#Logging
Logging can be controlled using LogObserver provided along or you can use your own LogObserver
twistd --logger carbonforwarderlogging.forwarder_log_observer.get_log_observer blueflood-forward
