We were having problems with telegraf talking to
carbon-relay-ng using the graphite output. When
the carbon-relay-ng server restarted the connection
the telegraf side would go into CLOSE_WAIT but telegraf
would continue to send statistics through the connection.
Reading around it seems you need to a read from the connection
and see a EOF error. We've implemented this and added a test
that replicates roughly the error we were having.
Pair: @whpearson @joshmyers
main reasons behind this:
- make adding/removing tags cheap
- make adding/removing fields cheap
- make parsing cheaper
- make parse -> decorate -> write out bytes metric flow much faster
Refactor serializer to use byte buffer
This constitutes a large change in how we will parse different data
formats going forward (for the plugins that support it)
This is working off @henrypfhu's changes.
