Question about concurrency with custom appender [ InfluxDB Use Case ]

31 Mar 2015

      Hello,

I am new on this mailing list. I am a french java developper working in
Aix-en-Provence, France around Java and Docker. At the moment I am trying
to develop a bridge between InfluxDB (metrics database) and Logback. My
Proof of concept is here : https://github.com/zepouet/influxdb-logback

It is not final. Documentation will come each day. It is a young project.
Therefore I have a big question for global appender architecture.

I would like to create two loggers with one appender to reference two
differents series.
Is my solution right or may i fear threading problem with collision ?

Logback is wonderful with MDC and pattern rule for naming series.
So could you tell me if i am wrong since the beginning of my project or can
I go on ?
There is a lot of features from Logback to add in order to have a first
class citizen logger for InfluxDB.

Thanks you very much. Best regards
Nicolas
